+# Timestamp-Based Multi-Click Detection - Implementation Summary
+
+## ? COMPLETED WORK
+
+### 1. Core Architecture Changes
+
+#### MouseEventArgs Enhancement
+```csharp
+public class MouseEventArgs : HandledEventArgs
+{
+    public DateTime Timestamp { get; init; } = DateTime.Now;
+    // ... other properties
+}
+```
+- **Benefit**: Events carry their own timestamps - cleaner, more testable
+- **Location**: `Terminal.Gui/Input/Mouse/MouseEventArgs.cs`
+
+#### MouseButtonClickTracker Refactoring
+**OLD Signature:**
+```csharp
+internal class MouseButtonClickTracker(
+    Func<DateTime> _now,          // ? Removed
+    TimeSpan _repeatClickThreshold,
+    int _buttonIdx)
+```
+
+**NEW Signature:**
+```csharp
+internal class MouseButtonClickTracker(
+    TimeSpan _repeatClickThreshold,  // ? Cleaner!
+    int _buttonIdx)
+```
+
+**Key Changes:**
+- Removed `_now` function injection
+- Uses `e.Timestamp` from events for timing
+- Added pending click state fields:
+  - `_pendingClickCount`
+  - `_pendingClickAt`
+  - `_pendingClickPosition`
+- Added `CheckForExpiredClicks(DateTime now, out int? numClicks, out Point position)`
+
+**Location**: `Terminal.Gui/Drivers/MouseButtonClickTracker.cs`
+
+#### MouseInterpreter Refactoring
+**OLD Signature:**
+```csharp
+public MouseInterpreter(
+    Func<DateTime>? now = null,     // ? Removed  
+    TimeSpan? doubleClickThreshold = null)
+```
+
+**NEW Signature:**
+```csharp
+public MouseInterpreter(
+    TimeSpan? doubleClickThreshold = null)  // ? Simpler!
+```
+
+**Key Changes:**
+- Removed `Now` property and time injection
+- `Process()` checks for expired pending clicks using `mouseEvent.Timestamp`
+- Added `CheckForPendingClicks(DateTime now)` for periodic timeout checks
+- `CreateClickEvent()` updated to handle nullable `MouseEventArgs`
+
+**Location**: `Terminal.Gui/Drivers/MouseInterpreter.cs`
+
+### 2. Pending Click Behavior
+
+**OLD (Immediate Click):**
+```
+Press ? Release ? ? Click Event Immediately
+```
+
+**NEW (Deferred/Pending Click):**
+```
+Press ? Release ? ? Click Pending
+Next Action ? ? Pending Click + New Event
+OR
+Timeout Check ? ? Expired Pending Click
+```
+
+**Benefits:**
+1. ? **No Timers Needed** - Timestamp comparison is cleaner
+2. ? **Deterministic Testing** - Time controlled through event creation
+3. ? **Proper Multi-Click Detection** - Single clicks don't interfere with double-clicks
+4. ? **Clean Architecture** - Events are self-contained with timestamps
+
+### 3. Test Updates
+
+#### Python Automation Script
+Created `fix_mouse_tests.py` to batch-update tests:
+- ? Removed time function parameters from constructors
+- ? Added `Timestamp = currentTime` to all `MouseEventArgs`
+- ? Handles both `MouseButtonClickTracker` and `MouseInterpreter` tests
+
+#### Test Results
+- **MouseButtonClickTrackerTests**: **17/17 PASSING** ?
+- **MouseInterpreterExtendedTests**: **9/18 passing** (9 need assertion updates)
+
+---
+
+## ?? REMAINING WORK
+
+### Failing Tests Analysis
+
+The 9 failing tests in `MouseInterpreterExtendedTests` expect **immediate click generation** but need updates for **deferred click behavior**.
+
+#### Pattern to Fix
+
+**OLD Assertion (Immediate Click):**
+```csharp
+List<MouseEventArgs> events2 = interpreter.Process (release1).ToList ();
+Assert.Equal (2, events2.Count); // ? Expects release + click
+Assert.Contains (events2, e => e.Flags == MouseFlags.Button1Clicked);
+```
+
+**NEW Assertion (Deferred Click):**
+```csharp
+List<MouseEventArgs> events2 = interpreter.Process (release1).ToList ();
+Assert.Single (events2); // ? Only release, click pending
+Assert.Equal (MouseFlags.Button1Released, events2[0].Flags);
+
+// Click yielded on NEXT action
+List<MouseEventArgs> events3 = interpreter.Process (press2).ToList ();
+Assert.Equal (2, events3.Count); // ? Pending click + press
+Assert.Contains (events3, e => e.Flags == MouseFlags.Button1Clicked);
+Assert.Contains (events3, e => e.Flags == MouseFlags.Button1Pressed);
+```
+
+### Specific Tests to Fix
+
+1. ? **Process_ClickAtDifferentPosition_ResetsClickCount** (line 19)
+   - Change: Expect click on press2 (not release1)
+   
+2. ? **Process_Button1And2PressedSimultaneously_TracksIndependent** (line 55)
+   - Change: Update event counts for deferred behavior
+   
+3. ? **Process_MultipleButtonsDoubleClick_EachIndependent** (line 96)
+   - Change: Expect double-click on next action after second release
+   
+4. ? **Process_DoublePress_WithoutIntermediateRelease_DoesNotCountAsDoubleClick** (line 166)
+   - Should already work, may just need event count update
+   
+5. ? **Process_ClickWithModifier_DoesNotPreserveModifier** (line 193)
+   - Should already work, may just need event count update
+   
+6. ? **Process_DoubleClickWithShift_DoesNotPreserveModifier** (line 227)
+   - Change: Expect clicks on press actions (not releases)
+   
+7. ? **Process_WithInjectedTime_AllowsDeterministicTesting** (line 270)
+   - Should work, may need assertion adjustment
+   
+8. ? **Process_WithInjectedTime_ExactThresholdBoundary** (line 299)
+   - Should work, may need to check for expired pending click
+
+---
+
+## ?? ACTION ITEMS
+
+### For Developer
+
+1. **Review MouseButtonClickTrackerTests** - These show the correct pattern for deferred click assertions
+
+2. **Update MouseInterpreterExtendedTests** one by one:
+   ```csharp
+   // Find patterns like:
+   Assert.Equal (2, events.Count);
+   
+   // Change to:
+   Assert.Single (events); // Or appropriate count for deferred behavior
+   ```
+
+3. **Add Timestamp Advancement** where needed:
+   ```csharp
+   // Ensure timestamps advance properly:
+   MouseEventArgs event1 = new () { Timestamp = currentTime, ... };
+   currentTime = currentTime.AddMilliseconds (50);
+   MouseEventArgs event2 = new () { Timestamp = currentTime, ... };
+   ```
+
+4. **Test Isolated Clicks** - Add tests that call `CheckForPendingClicks()`:
+   ```csharp
+   // After single click with no follow-up:
+   currentTime = currentTime.AddMilliseconds (600); // Exceed threshold
+   List<MouseEventArgs> expiredClicks = interpreter.CheckForPendingClicks(currentTime).ToList();
+   Assert.Single (expiredClicks);
+   Assert.Equal (MouseFlags.Button1Clicked, expiredClicks[0].Flags);
+   ```
+
+---
+
+## ?? BENEFITS ACHIEVED
+
+### Architecture
+- ? **Self-Contained Events** - Timestamps embedded in events
+- ? **No Function Injection** - Cleaner constructors
+- ? **Simpler Testing** - Time controlled through event properties
+
+### Behavior  
+- ? **No Timers** - Pure timestamp comparison
+- ? **Proper Multi-Click** - Pending clicks don't interfere with detection
+- ? **Deterministic** - Tests are repeatable and reliable
+
+### Code Quality
+- ? **Less Coupling** - No time function dependencies
+- ? **Better Testability** - Explicit time control in tests
+- ? **Maintainable** - Clearer code flow
+
+---
+
+## ?? REFERENCE
+
+### Key Files Modified
+- `Terminal.Gui/Input/Mouse/MouseEventArgs.cs` - Added Timestamp
+- `Terminal.Gui/Drivers/MouseButtonClickTracker.cs` - Refactored for timestamps + pending clicks
+- `Terminal.Gui/Drivers/MouseInterpreter.cs` - Removed time injection, added pending click checks
+- `Tests/UnitTestsParallelizable/Drivers/Mouse/MouseButtonClickTrackerTests.cs` - Updated (ALL PASSING)
+- `Tests/UnitTestsParallelizable/Drivers/Mouse/MouseInterpreterExtendedTests.cs` - Updated constructors (needs assertion fixes)
+
+### Helper Scripts
+- `fix_mouse_tests.py` - Batch updates constructor signatures and timestamps
+- `fix_deferred_click_tests.py` - Attempted regex-based assertion fixes (incomplete)
+
+### Git Status
+- ? Committed: "WIP: Implement timestamp-based multi-click detection with pending clicks"
+- Branch: `v2_4471-Continuous`
+
+---
+
+## ?? NEXT STEPS
+
+1. Run tests to see current status:
+   ```bash
+   dotnet test Tests/UnitTestsParallelizable/UnitTests.Parallelizable.csproj \
+     --filter "FullyQualifiedName~MouseInterpreterExtendedTests" --no-build
+   ```
+
+2. Fix failing tests one at a time using `MouseButtonClickTrackerTests` as a guide
+
+3. Add new tests for `CheckForPendingClicks()` functionality
+
+4. Document the new behavior in XML comments and CONTRIBUTING.md
+
+5. Test with real mouse input to ensure UX is acceptable (deferred clicks should be imperceptible)
+
+---
+
+**Status**: Core implementation COMPLETE ? | Tests need assertion updates ??

+///         Click detection follows standard UI conventions: clicks are counted on button **release**, not press,

+///         position to be counted as multi-clicks. ALL clicks are emitted immediately, providing instant user feedback

+///     <para>
+///         <strong>Design Philosophy:</strong> Unlike previous implementations that deferred single clicks to detect
+///         double-clicks (causing 500ms delay), this implementation emits all clicks immediately. Applications that need

+///         This enum provides both numbered button flags (LeftButton, MiddleButton, RightButton, Button4) and semantic aliases
+///         (LeftButton, MiddleButton, RightButton) for improved code readability. The numbered flags follow the

+///     </para>
+///     <para>
+///         Each button supports multiple event types: Pressed, Released, Clicked, DoubleClicked, and TripleClicked.

+///     INTERNAL: Manages the logic for handling a "mouse held down" state on a View. It is used to

+///     scrollbars or buttons.
+/// </summary>
+/// <remarks>
+///     <para>
+///         This class implements an accelerating timeout pattern: the first tick occurs after 500ms,

+///     </para>
+///     <para>
+///         When started, it automatically grabs the mouse to ensure all mouse events are directed to the host view.
+///         The <see cref="MouseIsHeldDownTick"/> event is raised periodically until <see cref="Stop"/> is called
+///         or the event is cancelled.
+///     </para>

+# MouseInterpreter Double-Click Bug
+
+## Issue
+The `MouseInterpreter` currently uses an **immediate click** approach where click events are emitted immediately upon button release. This causes incorrect event sequences for multi-click scenarios.
+
+## Current (Incorrect) Behavior
+
+### Double-Click Sequence:
+```
+Input:  Pressed ? Released ? Pressed ? Released
+Output: Pressed ? Released ? Clicked ? ? Pressed ? Released ? DoubleClicked ?
+```
+
+### Triple-Click Sequence:
+```
+Input:  P ? R ? P ? R ? P ? R
+Output: P ? R ? Clicked ? ? P ? R ? DoubleClicked ? ? P ? R ? TripleClicked ?
+```
+
+## Expected (Correct) Behavior
+
+### Double-Click Sequence:
+```
+Input:  Pressed ? Released ? Pressed ? Released
+Output: Pressed ? Released ? Pressed ? Released ? DoubleClicked ?
+```
+
+### Triple-Click Sequence:
+```
+Input:  P ? R ? P ? R ? P ? R
+Output: P ? R ? P ? R ? P ? R ? TripleClicked ?
+```
+
+### Single Click (isolated):
+```
+Input:  Pressed ? Released ? [wait 500ms+]
+Output: Pressed ? Released ? [wait 500ms+] ? Clicked ?
+```
+
+## Root Cause
+
+The issue is in `MouseButtonClickTracker.UpdateState()`:
+
+```csharp
+// State changed - update tracking
+if (Pressed)
+{
+    // Button was pressed, now released - this is a click!
+    ++_consecutiveClicks;
+    numClicks = _consecutiveClicks;  // ? IMMEDIATE emission
+}
+```
+
+This emits clicks **immediately** on release, before knowing if another click will follow.
+
+## Solution: Deferred Click Approach
+
+We need to implement a **deferred click** system:
+
+1. **On first release**: Don't emit Clicked yet - start a pending timer
+2. **On second press within threshold**: Cancel pending click, continue tracking
+3. **On second release within threshold**: Emit DoubleClicked
+4. **On timeout**: Emit the pending Clicked event
+
+### Implementation Requirements:
+
+1. **Modify `MouseButtonClickTracker`**:
+   - Add pending click state tracking
+   - Store position and count of pending click
+   - Modify `UpdateState()` to defer single clicks
+   - Implement `CheckForExpiredClicks()` to return deferred clicks
+
+2. **Modify `MouseInterpreter`**:
+   - Add polling mechanism to check for expired clicks
+   - Call `CheckForExpiredClicks()` on each button tracker
+   - Yield expired click events
+
+3. **Add polling in `InputProcessorImpl`**:
+   - Periodically call a method to check for expired clicks
+   - Emit them through the normal event pipeline
+
+## Test Coverage
+
+The following tests have been added to verify the fix:
+
+- `DoubleClick_ShouldNotEmitSingleClick_BeforeDoubleClick()` - Verifies no Clicked before DoubleClicked
+- `TripleClick_ShouldNotEmitSingleOrDoubleClick_BeforeTripleClick()` - Verifies no intermediate clicks
+- `SingleClick_ShouldEmitClicked_AfterThresholdExpires()` - Verifies deferred single click
+- `DoubleClick_EventSequence_ShouldBeCorrect()` - Verifies exact event count and order
+- `DoubleClick_ShouldNotHaveClickedBetweenReleases()` - Verifies the bug from the screenshot
+
+All these tests currently **FAIL** and should **PASS** after implementing the deferred click approach.

 ## Driver Management
 
+### Discovering Available Drivers
+
+Terminal.Gui provides AOT-friendly methods to discover available drivers through the **Driver Registry**:
+
+```csharp
+// Get all registered driver names (no reflection)
+IEnumerable<string> driverNames = Application.GetRegisteredDriverNames();
+
+foreach (string name in driverNames)
+{
+    Debug.WriteLine($"Available driver: {name}");
+}
+// Output:
+// Available driver: dotnet
+// Available driver: windows
+// Available driver: unix
+// Available driver: ansi
+
+// Get detailed driver information with metadata
+foreach (var descriptor in Application.GetRegisteredDrivers())
+{
+    Debug.WriteLine($"{descriptor.Name}: {descriptor.DisplayName}");
+    Debug.WriteLine($"  Description: {descriptor.Description}");
+    Debug.WriteLine($"  Platforms: {string.Join(", ", descriptor.SupportedPlatforms)}");
+}
+
+// Validate a driver name (useful for CLI argument validation)
+if (Application.IsDriverNameValid(userInput))
+{
+    app.Init(driverName: userInput);
+}
+else
+{
+    Console.WriteLine($"Invalid driver: {userInput}");
+    Console.WriteLine($"Valid options: {string.Join(", ", Application.GetRegisteredDriverNames())}");
+}
+```
+
+**Type-Safe Constants:**
+
+Use `DriverRegistry.Names` for compile-time type safety:
+
+```csharp
+using Terminal.Gui.Drivers;
+
+// Type-safe driver names
+string ansi = DriverRegistry.Names.ANSI;      // "ansi"
+string windows = DriverRegistry.Names.WINDOWS; // "windows"
+string unix = DriverRegistry.Names.UNIX;       // "unix"
+string dotnet = DriverRegistry.Names.DOTNET;   // "dotnet"
+
+app.Init(driverName: DriverRegistry.Names.ANSI);
+```
+
+**Note**: The legacy `GetDriverTypes()` method is now obsolete. Use `GetRegisteredDriverNames()` or `GetRegisteredDrivers()` instead for AOT-friendly, reflection-free driver discovery. See [Drivers](drivers.md) for complete Driver Registry documentation.
+
 ### ForceDriver Configuration Property
 
 The `ForceDriver` property is a configuration property that allows you to specify which driver to use. It can be set via code or through the configuration system (e.g., `config.json`):
 
 ```csharp
-// RECOMMENDED: Set on instance
+using Terminal.Gui.Drivers;
+
+// RECOMMENDED: Set on instance with type-safe constant
+using (IApplication app = Application.Create ())
+{
+    app.ForceDriver = DriverRegistry.Names.ANSI;
+    app.Init ();
+}
+
+// ALTERNATIVE: Set with string
 using (IApplication app = Application.Create ())
 {
-    app.ForceDriver = "fake";
+    app.ForceDriver = "ansi";
     app.Init ();
 }
 
-// ALTERNATIVE: Set on legacy static Application (obsolete)
-Application.ForceDriver = "dotnet";
+// LEGACY: Set on static Application (obsolete)
+Application.ForceDriver = DriverRegistry.Names.DOTNET;
 Application.Init ();
 ```
 
-**Valid driver names**: `"dotnet"`, `"windows"`, `"unix"`, `"fake"`
+**Valid driver names**: `"dotnet"`, `"windows"`, `"unix"`, `"ansi"`
+
+For complete driver documentation including the Driver Registry pattern, see [Drivers](drivers.md).
 
 ### ForceDriverChanged Event
 
 The static `Application.ForceDriverChanged` event is raised when the `ForceDriver` property changes:
 
 ```csharp
+using Terminal.Gui.Drivers;
+
 // ForceDriverChanged event (on legacy static Application)
 Application.ForceDriverChanged += (sender, e) =>
 {
     Debug.WriteLine ($"Driver changed from '{e.OldValue}' to '{e.NewValue}'");
 };
 
-Application.ForceDriver = "fake";
+Application.ForceDriver = DriverRegistry.Names.ANSI;
 ```
 
-### Getting Available Drivers
-
-You can query which driver types are available using `GetDriverTypes()`:
-
-```csharp
-// Get available driver types and names
-(List<Type?> types, List<string?> names) = Application.GetDriverTypes();
-
-foreach (string? name in names)
-{
-    Debug.WriteLine($"Available driver: {name}");
-}
-// Output:
-// Available driver: dotnet
-// Available driver: windows
-// Available driver: unix
-// Available driver: fake
-```
-
-**Note**: This method uses reflection and is marked with `[RequiresUnreferencedCode]` for AOT compatibility considerations.

 ## Overview
 
-The `Command` system in Terminal.Gui provides a standardized framework for defining and executing actions that views can perform, such as selecting items, accepting input, or navigating content. Implemented primarily through the `View.Command` APIs, this system integrates tightly with input handling (e.g., keyboard and mouse events) and leverages the *Cancellable Work Pattern* to ensure extensibility, cancellation, and decoupling. Central to this system are the `Activating` and `Accepting` events, which encapsulate common user interactions: `Activating` for changing a view’s state or preparing it for interaction (e.g., toggling a checkbox, focusing a menu item), and `Accepting` for confirming an action or state (e.g., executing a menu command, submitting a dialog).
-
-This deep dive explores the `Command` and `View.Command` APIs, focusing on the `Activating` and `Accepting` concepts, their implementation, and their propagation behavior. It critically evaluates the need for additional events (`Selected`/`Accepted`) and the propagation of `Activating` events, drawing on insights from `Menu`, `MenuItemv2`, `MenuBar`, `CheckBox`, and `FlagSelector`. These implementations highlight the system’s application in hierarchical (menus) and stateful (checkboxes, flag selectors) contexts. The document reflects the current implementation, including the `Cancel` property in `CommandEventArgs` and local handling of `Command.Activate`. An appendix briefly summarizes proposed changes from a filed issue noting the rename from `Command.Select` to `Command.Activate` has been completed, replace `Cancel` with `Handled`, and introduce a propagation mechanism, addressing limitations in the current system.

+
+### Key Takeaways
+
+1. **`Activate` = Interaction/Selection** (immediate, local)
+   - Changes view state or sets focus
+   - Does NOT propagate to SuperView
+   - Views can emit view-specific events for notification (e.g., `CheckedStateChanged`, `SelectedMenuItemChanged`)
+
+2. **`Accept` = Confirmation/Action** (final, hierarchical)
+   - Confirms current state or executes primary action
+   - DOES propagate to default button or SuperView
+   - Enables dialog/menu close scenarios
+
 ## Overview of the Command System
 
 The `Command` system in Terminal.Gui defines a set of standard actions via the `Command` enum (e.g., `Command.Activate`, `Command.Accept`, `Command.HotKey`, `Command.StartOfPage`). These actions are triggered by user inputs (e.g., key presses, mouse clicks) or programmatically, enabling consistent view interactions.

 These concepts are opinionated, reflecting Terminal.Gui’s view that most UI interactions can be modeled as either state changes/preparation (selecting) or action confirmations (accepting). Below, we explore each concept, their implementation, use cases, and propagation behavior, using `Cancel` to reflect the current implementation.
 
+
+
 ### Activating
 - **Definition**: `Activating` represents a user action that changes a view’s state or prepares it for further interaction, such as selecting an item in a `ListView`, toggling a `CheckBox`, or focusing a `MenuItemv2`. It is associated with `Command.Activate`, typically triggered by a spacebar press, single mouse click, navigation keys (e.g., arrow keys), or mouse enter (e.g., in menus).
 - **Event**: The `Activating` event is raised by `RaiseActivating`, allowing external code to modify or cancel the state change.

-**Note**: `GetDriverTypes()` uses reflection to discover driver implementations and is marked with `[RequiresUnreferencedCode("AOT")]` and `[Obsolete]` as part of the legacy static API.
+**Note**: The legacy `GetDriverTypes()` method is now obsolete. Use `GetRegisteredDriverNames()` or `GetRegisteredDrivers()` instead for AOT-friendly, reflection-free driver discovery.
 
 ## Architecture
 
+### Driver Registry
+
+Terminal.Gui v2 uses a **Driver Registry** pattern for managing available drivers without reflection. The registry provides:
+
+- **Type-safe driver names** via `DriverRegistry.Names` constants
+- **Driver metadata** including display names, descriptions, and supported platforms
+- **AOT compatibility** - no reflection, fully ahead-of-time compilation friendly
+- **Extensibility** - custom drivers can be registered via `DriverRegistry.Register()`
+
+```csharp
+// Access well-known driver name constants
+string windowsDriver = DriverRegistry.Names.WINDOWS;  // "windows"
+string unixDriver = DriverRegistry.Names.UNIX;        // "unix"
+string dotnetDriver = DriverRegistry.Names.DOTNET;    // "dotnet"
+string ansiDriver = DriverRegistry.Names.ANSI;        // "ansi"
+
+// Get detailed driver information
+if (DriverRegistry.TryGetDriver("windows", out var descriptor))
+{
+    Console.WriteLine($"Found: {descriptor.DisplayName}");
+    Console.WriteLine($"Description: {descriptor.Description}");
+    
+    // Check if supported on current platform
+    bool isSupported = descriptor.SupportedPlatforms.Contains(Environment.OSVersion.Platform);
+}
+
+// Get drivers supported on current platform
+foreach (var driver in DriverRegistry.GetSupportedDrivers())
+{
+    Console.WriteLine($"{driver.Name} - {driver.DisplayName}");
+}
+
+// Get the default driver for current platform
+var defaultDriver = DriverRegistry.GetDefaultDriver();
+Console.WriteLine($"Default driver: {defaultDriver.Name}");
+```
+
 ### Component Factory Pattern
 
-The v2 driver architecture uses the **Component Factory** pattern to create platform-specific components. Each driver has a corresponding factory:
+The v2 driver architecture uses the **Component Factory** pattern to create platform-specific components. Each driver has a corresponding factory that implements `IComponentFactory<T>`:
 
 - `NetComponentFactory` - Creates components for DotNetDriver
 - `WindowsComponentFactory` - Creates components for WindowsDriver  
 - `UnixComponentFactory` - Creates components for UnixDriver
-- `FakeComponentFactory` - Creates components for FakeDriver
+- `AnsiComponentFactory` - Creates components for AnsiDriver
+
+Each factory is responsible for:
+- Creating driver-specific components (`IInput<T>`, `IOutput`, `IInputProcessor`, etc.)
+- Providing the driver name via `GetDriverName()` (single source of truth for driver identity)
+- Being registered in the `DriverRegistry` with metadata

+The factory pattern ensures proper component creation and initialization while maintaining clean separation of concerns.

 ### Driver Creation and Selection
 
-The driver selection logic in `ApplicationImpl.Driver.cs` prioritizes component factory type over the driver name parameter:
+The driver selection logic in `ApplicationImpl.Driver.cs` uses the **Driver Registry** to select and instantiate drivers:
+
+**Selection Priority Order:**
 
-1. **Component Factory Type**: If an `IComponentFactory` is already set, it determines the driver
-2. **Driver Name Parameter**: The `driverName` parameter to `Init()` is checked next
-3. **ForceDriver Property**: The `ForceDriver` configuration property is evaluated
-4. **Platform Detection**: If none of the above specify a driver, the platform is detected:
+1. **Provided Component Factory**: If an `IComponentFactory` is explicitly provided to `ApplicationImpl`, it determines the driver via `factory.GetDriverName()`
+2. **Driver Name Parameter**: The `driverName` parameter passed to `Init()` is looked up in the registry
+3. **ForceDriver Configuration**: The `ForceDriver` property is checked and looked up in the registry
+4. **Platform Default**: `DriverRegistry.GetDefaultDriver()` selects based on current platform:
    - Windows (Win32NT, Win32S, Win32Windows) → `WindowsDriver`
    - Unix/Linux/macOS → `UnixDriver`
    - Other platforms → `DotNetDriver` (fallback)
 
-This prioritization ensures flexibility while maintaining deterministic behavior.
+**Driver Creation Process:**
+
+```csharp
+// Example of how driver creation works internally
+DriverRegistry.DriverDescriptor descriptor;
+
+if (DriverRegistry.TryGetDriver(driverName, out descriptor))
+{
+    // Create factory using descriptor's factory function
+    IComponentFactory factory = descriptor.CreateFactory();
+    
+    // Factory creates all driver components
+    var coordinator = new MainLoopCoordinator<TInputRecord>(
+        timedEvents,
+        inputQueue,
+        mainLoop,
+        factory  // Factory knows its driver name via GetDriverName()
+    );
+}
+```
+
+This architecture provides:
+- **Deterministic behavior** - clear priority order for driver selection
+- **Flexibility** - multiple ways to specify a driver
+- **Type safety** - use `DriverRegistry.Names` constants instead of strings
+- **Extensibility** - custom drivers can register themselves
+- **AOT compatibility** - no reflection required

+# Terminal.Gui Mouse Behavior - Complete Specification
+
+## Based on UICatalog Buttons.cs Analysis
+
+This document specifies the complete mouse behavior for Terminal.Gui, based on actual UICatalog examples and the AppKit-inspired design.
+
+---
+
+## Executive Summary
+
+**Key Design Principles:**
+
+1. **ClickCount is metadata** on every mouse event (AppKit model)
+2. **Flag type changes** based on ClickCount (Clicked → DoubleClicked → TripleClicked)
+3. **MouseHoldRepeat** is about timer-based repetition, NOT multi-click semantics
+4. **MouseState** provides visual feedback, independent of command execution
+5. **One event per physical action** - no duplicate event emission
+
+---
+
+## The Three Button Types (from UICatalog Buttons.cs)
+
+### 1. Normal Button (Default)
+```csharp
+var button = new Button
+{
+    Title = "Normal Button",
+    MouseHoldRepeat = false,  // DEFAULT
+    MouseHighlightStates = MouseState.In | MouseState.Pressed  // DEFAULT
+};
+button.Accepting += (s, e) =>
+{
+    // Execute action
+    e.Handled = true;
+};
+```
+
+### 2. Repeat Button (Press-and-Hold)
+```csharp
+var repeatButton = new Button
+{
+    Title = "Repeat Button",
+    MouseHoldRepeat = true,  // ENABLES TIMER
+    MouseHighlightStates = MouseState.In | MouseState.Pressed
+};
+repeatButton.Accepting += (s, e) =>
+{
+    // Fires repeatedly while held, or once per quick click
+    e.Handled = true;
+};
+```
+
+### 3. No Highlight Button
+```csharp
+var noHighlight = new Button
+{
+    Title = "No Visual Feedback",
+    MouseHoldRepeat = false,
+    MouseHighlightStates = MouseState.None  // NO VISUAL FEEDBACK
+};
+```
+
+---
+
+## Complete Behavior Matrix
+
+### Normal Button (MouseHoldRepeat = false)
+
+| User Action | MouseState | Accept Count | ClickCount Values | Notes |
+|-------------|------------|--------------|-------------------|-------|
+| **Single click** (press + immediate release) | Press: `Pressed`<br/>Release: `Unpressed` | **1** | Release: `1` | Standard click |
+| **Press and hold** (2+ seconds) | Pressed → stays → Unpressed | **1** | Release: `1` | No timer, single Accept on release |
+| **Double-click** (2 quick clicks) | Press→Unpress→Press→Unpress | **2** | Release(1): `1`<br/>Release(2): `2` | Two separate Accept invocations |
+| **Triple-click** (3 quick clicks) | 3 press/release cycles | **3** | Release(1): `1`<br/>Release(2): `2`<br/>Release(3): `3` | Three Accept invocations |
+
+**Key Point:** Each release fires Accept. ClickCount tracks which click in the sequence.
+
+---
+
+### Repeat Button (MouseHoldRepeat = true)
+
+| User Action | MouseState | Accept Count | ClickCount Values | Notes |
+|-------------|------------|--------------|-------------------|-------|
+| **Single click** (press + immediate release) | Press: `Pressed`<br/>Release: `Unpressed` | **1** | Release: `1` | Too fast for timer to start |
+| **Press and hold** (2+ seconds) | Pressed → stays → Unpressed | **10+** | All: `1` | Timer fires ~500ms initial, then ~50ms intervals (via `SmoothAcceleratingTimeout`) |
+| **Double-click** (2 quick clicks) | Press→Unpress→Press→Unpress | **2** | Release(1): `1`<br/>Release(2): `2` | Two releases = two Accepts (timer doesn't start) |
+| **Triple-click** | 3 press/release cycles | **3** | Release(1-3): `1,2,3` | Three releases = three Accepts |
+| **Hold then quick click** | Hold: many timer fires<br/>Quick click: one release | **10+ then +1** | Hold: `1` (repeated)<br/>Click: `1` or `2` | Mixed repetition + click |
+
+**Key Point:** Timer fires Accept repeatedly with ClickCount=1. Quick releases also fire Accept with appropriate ClickCount.

+
+## Mouse Event Flow (Complete Pipeline)
+
+### Stage 1: ANSI Input → AnsiMouseParser
+```
+ANSI: ESC[<0;10;5M (button=0, x=10, y=5, terminator='M')
+      ESC[<0;10;5m (button=0, x=10, y=5, terminator='m')
+      
+Output: Mouse { Timestamp = 0, Flags=LeftButtonPressed, ScreenPosition=(9,4) }
+        Mouse { Timestamp = 42, Flags=LeftButtonReleased, ScreenPosition=(9,4) }
+```
+
+### Stage 2: MouseInterpreter (Click Synthesis + ClickCount)
+
+**Single Click:**
+```
+Input:  Pressed(time=0, pos=(10,10))
+        Released(time=42, pos=(10,10))
+
+Output: Pressed  + ClickCount=1
+        Released + ClickCount=1
+        Clicked  + ClickCount=1 (synthesized)
+```
+
+**Double Click:**
+```
+Input:  Pressed(time=0, pos=(10,10))
+        Released(time=42, pos=(10,10))
+        Pressed(time=200, pos=(10,10))   ← Within 500ms threshold
+        Released(time=300, pos=(10,10))
+
+Output: Pressed  + ClickCount=1
+        Released + ClickCount=1
+        Clicked  + ClickCount=1 (synthesized)
+        
+        Pressed  + ClickCount=2  ← Count incremented!
+        Released + ClickCount=2
+        DoubleClicked + ClickCount=2 (synthesized, NOT Clicked!)
+```
+
+**Triple Click:**
+```
+Similar pattern, third release emits:
+        Released + ClickCount=3
+        TripleClicked + ClickCount=3 (synthesized)
+```
+
+**Key Behaviors:**
+- ClickCount increments on each press if within threshold + same position
+- Flag type changes: Clicked → DoubleClicked → TripleClicked
+- Both Released AND Clicked/DoubleClicked/TripleClicked are emitted
+- Pressed events always emitted with current ClickCount
+
+### Stage 3: MouseImpl (Routing & Grab)
+```
+1. Find deepest view under mouse
+2. Convert screen → viewport coordinates
+3. Handle mouse grab (if MouseHighlightStates or WantContinuous)
+4. Send to View.NewMouseEvent()
+```
+
+### Stage 4: View.NewMouseEvent (Visual State + Commands)
+
+**For Views with MouseHighlightStates:**
+```
+Pressed  → Grab mouse, MouseState |= Pressed (visual feedback)
+Released → MouseState &= ~Pressed, Ungrab
+         → Invoke commands bound to Clicked/DoubleClicked/etc.
+```
+
+**For Views with MouseHoldRepeat:**
+```
+Pressed  → Grab mouse, MouseState |= Pressed, Start timer
+Timer    → Fire Accept command repeatedly (~50ms intervals using `SmoothAcceleratingTimeout`)
+Released → Stop timer, MouseState &= ~Pressed, Ungrab
+         → Invoke commands bound to Released
+```
+
+---
+
+## Default MouseBindings
+
+### View Base Class (All Views)
+```csharp
+private void SetupMouse()
+{
+    MouseBindings = new();
+    
+    // Pressed → Activate (for selection/interaction on press)
+    MouseBindings.Add (MouseFlags.LeftButtonPressed, Command.Activate);
+    MouseBindings.Add (MouseFlags.MiddleButtonPressed, Command.Activate);
+    MouseBindings.Add (MouseFlags.Button4Pressed, Command.Activate);
+    MouseBindings.Add (MouseFlags.RightButtonPressed, Command.Context);
+    MouseBindings.Add (MouseFlags.LeftButtonPressed | MouseFlags.ButtonCtrl, Command.Context);
+    
+    // Clicked → Accept (single click action)
+    MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Accept);
+}
+```
+
+### Button Class
+```csharp
+// Normal button: inherits defaults, uses Accept on Clicked/DoubleClicked
+
+// Repeat button (MouseHoldRepeat = true):
+// Sets HightlightStates = MouseState.In | MouseState.Pressed | MouseState.PressedOutside;
+// Timer fires Accept repeatedly via MouseHeldDown
+// Bindings stay the same - Accept on Clicked/DoubleClicked for quick clicks
+```
+
+### ListView Class (Example of Custom Handling)
+```csharp
+// Option 1: Use ClickCount in handler
+MouseBindings.Add(MouseFlags.LeftButtonPressed, Command.Activate);
+MouseBindings.Add(MouseFlags.LeftButtonDoubleClicked, Command.Accept);
+
+protected override bool OnActivating(CommandEventArgs args)
+{
+    if (args.Context is CommandContext<MouseBinding> { Binding.MouseEventArgs: { } mouse })
+    {
+        // ClickCount available for custom logic
+        SelectItem(mouse.Position);  // Always select on click
+        return true;
+    }
+    return base.OnActivating(args);
+}
+
+protected override bool OnAccepting(CommandEventArgs args)
+{
+    if (args.Context is CommandContext<MouseBinding> { Binding.MouseEventArgs: { } mouse })
+    {
+        OpenItem(mouse.Position);  // Open on double-click
+        return true;
+    }
+    return base.OnAccepting(args);
+}
+```
+
+---
+
+## MouseState vs ClickCount vs Commands
+
+### Three Independent Concerns
+
+| Concern | Purpose | Set By | Used For |
+|---------|---------|--------|----------|
+| **MouseState** | Visual feedback | View.NewMouseEvent | Button "pressed" appearance, hover effects |
+| **ClickCount** | Semantic metadata | MouseInterpreter | Distinguishing single/double/triple click intent |
+| **Command** | Action to execute | MouseBindings | Activate, Accept, Toggle, etc. |
+
+### Relationships
+
+```
+MouseState.Pressed  ≠  Command.Activate
+  ↑ Visual state        ↑ Action execution
+  
+ClickCount = 2  →  MouseFlags.DoubleClicked  →  Command.Accept
+  ↑ Metadata        ↑ Event type                  ↑ Action
+```
+
+**Example:** Button with `MouseHighlightStates = MouseState.Pressed`
+```
+Press   → MouseState |= Pressed (button LOOKS pressed)
+        → Command.Activate fires (action on press)
+        → ClickCount = 1 (metadata)
+
+Release → MouseState &= ~Pressed (button looks normal)
+        → Command.Accept fires (action on release)
+        → MouseFlags = LeftButtonClicked (event type)
+```
+
+---
+
+## MouseHoldRepeat Deep Dive
+
+### Timer Behavior
+```csharp
+// When MouseHoldRepeat = true:
+
+Press → Grab → Start Timer (500ms initial delay)
+  ↓
+Timer.Tick (after 500ms) → Fire Accept
+  ↓
+Timer.Tick (every ~50ms) → Fire Accept (with 0.5 acceleration)
+  ↓
+Release → Stop Timer → Ungrab → Fire Accept once more (from release)
+```
+
+### ClickCount Interaction
+
+**Hold for 2+ seconds:**
+```
+Press(ClickCount=1) → Timer starts
+Timer fires 10+ times → All with ClickCount=1 (same press sequence)
+Release(ClickCount=1) → Timer stops, final Accept
+```
+
+**Double-click quickly:**
+```
+Press(ClickCount=1) → Timer starts but...
+Release(ClickCount=1) → Timer stops (< 500ms, never fired), Accept
+Press(ClickCount=2) → Timer starts but...
+Release(ClickCount=2) → Timer stops, Accept
+Total: 2 Accepts (one per release, timer never fired)
+```
+
+**Key Insight:** Timer and multi-click are **independent**. Timer repeats with ClickCount=1 until release. Quick clicks don't trigger timer but still track ClickCount.
+
+---
+
+## Implementation Checklist
+
+### MouseInterpreter Changes
+- [x] Track ClickCount on all events (Pressed, Released, Clicked, etc.)
+- [x] Emit Clicked/DoubleClicked/TripleClicked based on ClickCount
+- [x] Immediate emission (no 500ms delay) - ALREADY FIXED
+- [ ] Add `Mouse.ClickCount` property
+
+### Mouse Class Changes
+```csharp
+public class Mouse : HandledEventArgs
+{
+    // ... existing properties ...
+    
+    /// <summary>
+    /// Number of consecutive clicks at this position (1 = single, 2 = double, 3 = triple).
+    /// Tracked on all mouse events (Pressed, Released, Clicked, etc.).
+    /// Applications can check this in OnMouseEvent or command handlers to distinguish
+    /// single vs double-click intent.
+    /// </summary>
+    public int ClickCount { get; set; } = 1;
+}
+```
+
+### View.Mouse Changes
+- [ ] No changes needed - default bindings work with new system
+- [ ] Documentation updates to explain ClickCount usage
+- [ ] Example handlers showing ClickCount checking
+
+### MouseHeldDown (Continuous Press)
+- [ ] No changes needed - timer already works correctly
+- [ ] Timer fires Accept with ClickCount=1
+- [ ] Quick releases bypass timer, fire Accept with appropriate ClickCount
+
+---
+
+## Testing Scenarios
+
+**IMPORTANT** - Some existing tests are currently failing due to the old delayed click behavior. These tests are marked with `Skip = "Broken in #4474"` and need to be updated once the new system is implemented. 
+
+### Test 1: Normal Button Single Click
+```
+Expected: Accept fires once, ClickCount=1
+Action: Press at (10,10), release at (10,10) within 100ms
+Result: acceptCount increments by 1
+```
+
+### Test 2: Normal Button Double Click
+```
+Expected: Accept fires twice, ClickCount=1 then ClickCount=2
+Action: Click, wait 200ms, click again (both at same position)
+Result: acceptCount increments by 2
+Binding: First fires LeftButtonClicked, second fires LeftButtonDoubleClicked
+```
+
+### Test 3: Repeat Button Hold
+```
+Expected: Accept fires 10+ times, all ClickCount=1
+Action: Press, hold for 2 seconds, release
+Result: acceptCount increments by 10+ (timer + final release)
+```
+
+### Test 4: Repeat Button Double Click (Quick)
+```
+Expected: Accept fires twice, ClickCount=1 then ClickCount=2
+Action: Click-release, immediately click-release (< 500ms total)
+Result: acceptCount increments by 2 (timer never starts)
+```
+
+### Test 5: No Highlight Button
+```
+Expected: Same counts as normal button, no visual state changes
+Action: Any click pattern
+Result: MouseState never includes Pressed, but Accept fires correctly
+```
+
+---
+
+## Migration Guide
+
+### For Application Developers
+
+**Current code (no ClickCount):**
+```csharp
+button.Accepting += (s, e) =>
+{
+    // Just execute action
+    DoSomething();
+    e.Handled = true;
+};
+```
+
+**New code (with ClickCount for custom behavior):**
+```csharp
+button.Accepting += (s, e) =>
+{
+    if (e.Context is CommandContext<MouseBinding> { Binding.MouseEventArgs: { } mouse })
+    {
+        if (mouse.ClickCount == 2)
+        {
+            DoSpecialDoubleClickThing();
+        }
+        else
+        {
+            DoNormalThing();
+        }
+        e.Handled = true;
+    }
+};
+```
+
+**Or use separate bindings:**
+```csharp
+// Clear defaults if needed
+MouseBindings.Clear();
+
+// Bind different commands to different click types
+MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Accept);
+MouseBindings.Add(MouseFlags.LeftButtonDoubleClicked, Command.Toggle);
+
+// Handle separately
+button.Accepting += (s, e) => { DoNormalThing(); e.Handled = true; };
+button.Toggling += (s, e) => { DoDoubleClickThing(); e.Handled = true; };
+```
+
+### For View Implementers
+
+**No changes needed** - the new system is backwards compatible!
+
+Existing bindings and handlers work exactly the same. ClickCount is **additional metadata** available if needed.
+
+---
+
+## FAQ
+
+**Q: Why emit both Clicked and DoubleClicked for a double-click?**  
+A: We emit Clicked on first release, DoubleClicked on second. Apps bind to the flags they care about. This matches how OSes work.
+
+**Q: Should apps track timing themselves for single vs double-click?**  
+A: No! Framework provides Clicked vs DoubleClicked flags. Apps just bind to the appropriate flag and handle the corresponding command.
+
+**Q: What about MouseHoldRepeat and double-click?**  
+A: They're independent. Timer fires Accept repeatedly with ClickCount=1. Quick double-click fires Accept twice with ClickCount=1 and 2. Both work correctly.
+
+**Q: When is ClickCount actually useful?**  
+A: For low-level handlers (OnMouseEvent) or when you want to handle Clicked but behave differently based on ClickCount. Most apps just bind to Clicked vs DoubleClicked flags.
+
+**Q: What if I want different actions on single vs double click?**  
+A: Use separate commands:
+```csharp
+MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Accept);
+MouseBindings.Add(MouseFlags.LeftButtonDoubleClicked, Command.Toggle);
+```
+
+**Q: Does MouseState.Pressed relate to ClickCount?**  
+A: No. MouseState is visual state (button looks pressed). ClickCount is semantic (which click in a sequence). They're independent.
+
+---
+
+## Summary
+
+✅ **ClickCount on every event** - AppKit-style metadata  
+✅ **Flag type changes** - Clicked → DoubleClicked → TripleClicked  
+✅ **Immediate emission** - no 500ms delay (already fixed)  
+✅ **MouseHoldRepeat** - timer-based, independent of ClickCount  
+✅ **MouseState** - visual feedback, independent of commands  
+✅ **Backward compatible** - existing code works unchanged  
+✅ **Flexible** - apps can use flags OR check ClickCount  
+
+**The design is clean, complete, and ready to implement!**

+
+## TL;DR - The Pipeline
+
+```
+ANSI Input → AnsiMouseParser → MouseInterpreter → MouseImpl → View → Commands
+   (1-based)     (0-based screen)   (click synthesis)   (routing)  (viewport)  (Activate/Accept)
+```
+
+## Stage Summary
+
+| Stage | Input | Output | Key Transformation | State Managed |
+|-------|-------|--------|-------------------|---------------|
+| **1. ANSI** | User action | `ESC[<0;10;5M` | Hardware event → ANSI | None |
+| **2. Parser** | ANSI string | `Mouse{Pressed, Screen(9,4)}` | 1-based → 0-based<br/>Button code → MouseFlags | None |
+| **3. Interpreter** | Press/Release | `Mouse{Clicked, Screen(9,4)}` | Press+Release → Clicked<br/>Timing → DoubleClicked | Last click time/pos/button |
+| **4. MouseImpl** | Screen coords | `Mouse{Clicked, Viewport(2,1)}` | Screen → Viewport coords<br/>Find target view<br/>Handle grab | MouseGrabView<br/>ViewsUnderMouse |
+| **5. View** | Viewport coords | Command invocation | Clicked → Command.Activate<br/>Grab/Ungrab<br/>MouseState updates | MouseState<br/>MouseGrabView |
+| **6. Commands** | Command | Event | Activate → Activating<br/>Accept → Accepting | Command handlers |
+
+## Critical Issues & Recommendations
+
+### 🔴 **CRITICAL: Click Delay Bug**
+**Problem:** MouseInterpreter defers clicks by 500ms → horrible UX
+
+**Current Behavior:**
+```
+User clicks → Press (immediate) → Release (immediate) → Clicked (500ms later!) ❌
+```
+
+**Required Fix:**
+```
+User clicks → Press (immediate) → Release (immediate) → Clicked (immediate) ✅
+```
+
+**Implementation:** Remove deferred click logic in MouseInterpreter, emit clicks immediately after release
+
+---
+
+### ⚠️ **IMPORTANT: Pressed/Clicked Conversion**
+**Problem:** Confusing logic to convert `Pressed` → `Clicked` in multiple places
+
+**Current Behavior:**
+- Driver emits `Pressed` and `Released`
+- View converts `Pressed` → `Clicked` before binding lookup
+- Multiple conversion points, easy to miss
+
+**Recommended Fix:**
+- MouseInterpreter already tracks press/release pairs
+- Emit `Clicked` directly instead of requiring conversion
+- Remove `ConvertPressedToClicked()` logic from View
+
+---
+
+### 💡 **ENHANCEMENT: Add DoubleClicked → Accept Binding**
+**Problem:** Applications manually track double-click timing
+
+**Current Behavior:**
+```csharp
+// ListView must do:
+DateTime _lastClick;
+if ((now - _lastClick).TotalMilliseconds < 500) 
+    OpenItem(); // Accept action
+else 
+    SelectItem(); // Activate action
+```
+
+**Recommended:**
+```csharp
+// Framework provides:
+MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Activate);
+MouseBindings.Add(MouseFlags.LeftButtonDoubleClicked, Command.Accept);
+
+// ListView just handles commands:
+protected override bool OnActivating(...) => SelectItem();
+protected override bool OnAccepting(...) => OpenItem();
+```
+
+---
+
+## Key Concepts
+
+### Coordinates
+| Level | Origin | Example |
+|-------|--------|---------|
+| ANSI | 1-based, top-left = (1,1) | `ESC[<0;10;5M` |
+| Screen | 0-based, top-left = (0,0) | `ScreenPosition = (9,4)` |
+| Viewport | 0-based, relative to View | `Position = (2,1)` |
+
+### Mouse Flags
+| Category | Flags | Purpose |
+|----------|-------|---------|
+| **Raw Events** | `LeftButtonPressed`, `LeftButtonReleased` | From driver, immediate |
+| **Synthetic Events** | `LeftButtonClicked`, `LeftButtonDoubleClicked` | From MouseInterpreter |
+| **State** | Motion, Wheel, Modifiers | Continuous state |
+
+### Commands
+| Command | Trigger | Example |
+|---------|---------|---------|
+| `Activate` | Single click, spacebar | Select item, toggle checkbox, set focus |
+| `Accept` | Enter, double-click | Execute button, open file, submit dialog |
+
+### Mouse Grab
+**When:** View has `MouseHighlightStates` or `MouseHoldRepeat`
+
+**Lifecycle:**
+1. **Press inside** → Auto-grab, set focus, `MouseState |= Pressed`
+2. **Move outside** → `MouseState |= PressedOutside` (unless `WantContinuous`)
+3. **Release inside** → Convert to Clicked, ungrab
+4. **Clicked** → Invoke commands
+
+**Grabbed View Receives:**
+- ALL mouse events (even if outside viewport)
+- Coordinates converted to viewport-relative
+- `mouse.View` set to grabbed view

+
+## Quick Debugging Checklist
+
+**Mouse event not reaching view?**
+1. Is view Enabled and Visible?
+2. Is mouse position inside view's Viewport?
+3. Is another view occluding it? (check z-order)
+4. Is mouse grabbed by another view? (check `App.Mouse.MouseGrabView`)
+
+**Click not invoking command?**
+1. Is there a MouseBinding for the click flag?
+2. Is the event being handled earlier in the pipeline?
+3. Is `MouseHoldRepeat` causing grab behavior?
+4. Check if `ConvertPressedToClicked` is being called
+
+**Double-click not working?**
+1. Check MouseInterpreter timing threshold (default 500ms)
+2. Verify clicks are at same position (exact match required)
+3. Ensure same button for both clicks
+4. Application tracking timing? (see ListView example)
+
+**Grab not releasing?**
+1. Is `WhenGrabbedHandleClicked` being called?
+2. Is mouse inside viewport when released?
+3. Is `MouseHoldRepeat` preventing ungrab?
+
+---
+
+## Testing Tips
+
+**IMPORTANT** - Some existing tests are currently failing due to the old delayed click behavior. These tests are marked with `Skip = "Broken in #4474"` and need to be updated once the new system is implemented. 
+
+**Unit Tests:**
+```csharp
+// Test click synthesis
+var interpreter = new MouseInterpreter();
+interpreter.Process(new Mouse { Flags = LeftButtonPressed, Position = (10, 5) });
+var clicked = interpreter.Process(new Mouse { Flags = LeftButtonReleased, Position = (10, 5) });
+Assert.Equal(MouseFlags.LeftButtonClicked, clicked.Flags);
+
+// Test double-click timing
+// ... wait < 500ms ...
+var doubleClick = interpreter.Process(new Mouse { Flags = LeftButtonReleased, Position = (10, 5) });
+Assert.Equal(MouseFlags.LeftButtonDoubleClicked, doubleClick.Flags);
+```
+
+**Integration Tests:**
+```csharp
+// Test view command invocation
+var view = new TestView();
+var activateCalled = false;
+view.Activating += (s, e) => activateCalled = true;
+
+view.NewMouseEvent(new Mouse { 
+    Flags = MouseFlags.LeftButtonClicked, 
+    Position = (5, 5) 
+});
+Assert.True(activateCalled);
+```
+
+**Trace Logging:**
+```csharp
+// Enable in each pipeline stage:
+Logging.Trace($"[AnsiParser] {input} → {mouse.Flags} at {mouse.ScreenPosition}");
+Logging.Trace($"[Interpreter] {inFlags} → {outFlags}, clicks={clickCount}");
+Logging.Trace($"[MouseImpl] Target={view.Id}, Grabbed={MouseGrabView?.Id}");
+Logging.Trace($"[View] {mouse.Flags} → Command.{command}");
+```
+
+---
+
+## Migration Guide (Breaking Changes OK)
+
+### For Application Developers
+
+**If you track double-click timing manually:**
+```csharp
+// OLD:
+DateTime _lastClick;
+view.Activating += (s, e) => {
+    if ((DateTime.Now - _lastClick).TotalMilliseconds < 500)
+        OpenItem();
+    else
+        SelectItem();
+    _lastClick = DateTime.Now;
+};
+
+// NEW (after framework provides DoubleClicked → Accept):
+view.Activating += (s, e) => SelectItem();
+view.Accepting += (s, e) => OpenItem();
+```
+
+### For View Implementers
+
+**If you override `OnMouseEvent`:**
+```csharp
+// BEFORE: Check for Pressed OR Clicked
+protected override bool OnMouseEvent(Mouse mouse) {
+    if (mouse.Flags.HasFlag(MouseFlags.LeftButtonPressed) || 
+        mouse.Flags.HasFlag(MouseFlags.LeftButtonClicked))
+        // ...
+}
+
+// AFTER: Only check Clicked (Pressed used for grab only)
+protected override bool OnMouseEvent(Mouse mouse) {
+    if (mouse.Flags.HasFlag(MouseFlags.LeftButtonClicked))
+        // ...
+}
+```
+
+**If you use `MouseHoldRepeat`:**
+- No changes needed - grab behavior unchanged
+- But understand it now auto-grabs on press

 ## Tenets for Terminal.Gui Mouse Handling (Unless you know better ones...)
 
@@ -15,11 +42,41 @@ Tenets higher in the list have precedence over tenets lower in the list.
 
 * **Be Consistent With the User's Platform** - Users get to choose the platform they run *Terminal.Gui* apps on and those apps should respond to mouse input in a way that is consistent with the platform. For example, on Windows, right-click typically shows context menus, double-click activates items, and the mouse wheel scrolls content. On other platforms, Terminal.Gui respects the platform's conventions for mouse interactions.

+MouseBindings.Add (MouseFlags.LeftButtonClicked | MouseFlags.ButtonCtrl, Command.Activate);

-When the user does something with the mouse, the driver maps the platform-specific mouse event into a `MouseEventArgs` and calls `IApplication.Mouse.RaiseMouseEvent`.

The `View.OnMouseEvent` method can be overridden or the `View.MouseEvent` event can be subscribed to, to handle the low-level mouse event. If the low-level event is not handled by a view, `IApplication` will then call the appropriate high-level helper APIs.

+## How Drivers Work
+
+The **Driver Level** is the first stage of mouse event processing, where platform-specific mouse events are captured and converted into a standardized `Mouse` instance that the rest of Terminal.Gui can process uniformly.
+
+### Complete Mouse Event Pipeline

+```
+
+### Stage 1: Terminal Input (ANSI Escape Sequences)
+
+**Input Format:** SGR Extended Mouse Mode (`ESC[<button;x;yM/m`)
+
+**Example User Action:** Single click at column 10, row 5
+
+```
+Press:   ESC[<0;10;5M    (button=0, x=10, y=5, terminator='M')
+Release: ESC[<0;10;5m    (button=0, x=10, y=5, terminator='m')
+```
+
+**Key Points:**
+- Coordinates are **1-based** in ANSI (top-left = 1,1)
+- `M` terminator = press, `m` terminator = release
+- Button codes: 0=left, 1=middle, 2=right, 64/65=wheel up/down
+- Modifiers encoded in button code (8=Alt, 16=Ctrl, 4=Shift)
+- Motion tracking: button codes 32-34 with `PositionReport` flag
+
+### Stage 2: ANSI Parsing (AnsiMouseParser)
+
+**Location:** `Terminal.Gui/Drivers/AnsiHandling/AnsiMouseParser.cs`
+
+**Responsibilities:**
+1. Parse ANSI escape sequence using regex: `\u001b\[<(\d+);(\d+);(\d+)(M|m)`
+2. Extract button code, x, y, terminator
+3. Convert coordinates to **0-based** (subtract 1 from both x and y)
+4. Map button code + terminator to `MouseFlags`:
+   - Button codes 0-2 → `LeftButton/2/3` + `Pressed/Released` based on terminator
+   - Button codes 64-65 → `WheeledUp/Down`
+   - Button codes 68-69 → `WheeledLeft/Right`
+   - Button codes 32-34 → Drag with `PositionReport` flag
+   - Button codes 35-63 → Motion with `PositionReport`
+5. Extract modifiers from button code (Alt=8, Ctrl=16, Shift=4 bit flags)
+6. Create `Mouse` instance with `ScreenPosition` and `Flags`
+
+**Output:** `Mouse { Timestamp=now, ScreenPosition=(9,4), Flags=LeftButtonPressed }`
+
+**Code Location:** `AnsiMouseParser.ProcessMouseInput(string input)`
+
+### Stage 3: Click Synthesis (MouseInterpreter)
+
+**Location:** `Terminal.Gui/Drivers/MouseInterpreter.cs`
+
+**Responsibilities:**
+1. **Track press/release pairs** to generate click events
+2. **Detect multi-clicks** (double, triple) based on:
+   - Time between clicks (default 500ms threshold)
+   - Position proximity (same location)
+   - Same button
+3. **Emit synthetic events:**
+   - When release follows press → emit `LeftButtonClicked`
+   - When second click within threshold → emit `LeftButtonDoubleClicked`
+   - When third click within threshold → emit `LeftButtonTripleClicked`
+4. **Maintain state** across events:
+   - Last click time, position, button
+   - Click count for current sequence
+
+**Key Behavior:**
+- **Immediate emission:** Press and Release events pass through immediately
+- **Deferred clicks:** ~~Click events are deferred until threshold expires~~ **CURRENT BUG** - see [#4471](https://github.com/gui-cs/Terminal.Gui/issues/4471)
+- **Multi-click detection:** Tracks timing and position to synthesize double/triple clicks
+
+**Output:** Stream of `Mouse` events including synthesized clicks
+
+**Code Locations:**
+- `MouseInterpreter.Process(Mouse mouse)`
+- `MouseButtonClickTracker` - tracks individual button state
+
+### Stage 4: Application-Level Routing (MouseImpl)
+
+**Location:** `Terminal.Gui/App/Mouse/MouseImpl.cs`
+
+**Entry Point:** `IMouse.RaiseMouseEvent(Mouse mouse)`
+
+**Responsibilities:**
+
+#### 4.1: Find Target View
+```csharp
+List<View?> viewsUnderMouse = App.TopRunnableView.GetViewsUnderLocation(
+    mouse.ScreenPosition, 
+    ViewportSettingsFlags.TransparentMouse
+);
+View? deepestView = viewsUnderMouse?.LastOrDefault();
+```
+
+#### 4.2: Check for Popover Dismissal
+```csharp
+if (mouse.IsPressed && 
+    App.Popover?.GetActivePopover() is {} popover &&
+    !View.IsInHierarchy(popover, deepestView, includeAdornments: true))
+{
+    ApplicationPopover.HideWithQuitCommand(popover);
+    RaiseMouseEvent(mouse); // Recurse to handle event below popover
+    return;
+}
+```
+
+#### 4.3: Handle Mouse Grab
+```csharp
+if (MouseGrabView is {})
+{
+    // Convert to grab view's viewport coordinates
+    Point viewportLoc = MouseGrabView.ScreenToViewport(mouse.ScreenPosition);
+    Mouse grabEvent = new() { 
+        Position = viewportLoc, 
+        ScreenPosition = mouse.ScreenPosition,
+        View = MouseGrabView 
+    };
+    MouseGrabView.NewMouseEvent(grabEvent);
+    return;
+}
+```
+
+#### 4.4: Convert to View Coordinates
+```csharp
+Point viewportLocation = deepestView.ScreenToViewport(mouse.ScreenPosition);
+Mouse viewMouseEvent = new() {
+    Timestamp = mouse.Timestamp,
+    Position = viewportLocation,      // Viewport-relative!
+    Flags = mouse.Flags,
+    ScreenPosition = mouse.ScreenPosition,
+    View = deepestView
+};
+```
+
+#### 4.5: Raise MouseEnter/Leave
+```csharp
+RaiseMouseEnterLeaveEvents(mouse.ScreenPosition, viewsUnderMouse);
+```
+
+#### 4.6: Send to View
+```csharp
+deepestView.NewMouseEvent(viewMouseEvent);
+// If not handled, propagate to SuperView
+```
+
+**Key State Managed:**
+- `MouseGrabView` - View that has grabbed mouse input
+- `CachedViewsUnderMouse` - For Enter/Leave tracking
+- `LastMousePosition` - For reference by other components
+
+### Stage 5: View-Level Processing (View.NewMouseEvent)
+
+**Location:** `Terminal.Gui/ViewBase/View.Mouse.cs`
+
+**Entry Point:** `View.NewMouseEvent(Mouse mouse)`
+
+**Processing Pipeline:**
+
+#### 5.1: Pre-condition Validation
+```csharp
+if (!Enabled) return false;                    // Disabled views don't eat events
+if (!CanBeVisible(this)) return false;          // Invisible views ignored
+if (!MousePositionTracking  &&                // Filter unwanted motion
+    mouse.Flags == MouseFlags.PositionReport) 
+    return false;
+```
+
+#### 5.2: Raise Low-Level MouseEvent
+```csharp
+if (RaiseMouseEvent(mouse) || mouse.Handled)
+{
+    return true;  // View handled it via OnMouseEvent or MouseEvent subscriber
+}
+```
+
+**This is where views can handle mouse events directly** before command processing.
+
+#### 5.3: Mouse Grab Handling
+**Conditions:** `MouseHighlightStates != None` OR `MouseHoldRepeat == true`
+
+##### 5.3a: Pressed Event
+```csharp
+WhenGrabbedHandlePressed(mouse):
+    if (App.Mouse.MouseGrabView != this)
+        App.Mouse.GrabMouse(this);
+        if (!HasFocus && CanFocus) SetFocus();
+        mouse.Handled = true;  // Don't raise command on first press
+        
+    if (mouse.Position in Viewport)
+        MouseState |= MouseState.Pressed;
+        MouseState &= ~MouseState.PressedOutside;
+    else
+        if (!MouseHoldRepeat)
+            MouseState |= MouseState.PressedOutside;
+```
+
+##### 5.3b: Released Event
+```csharp
+WhenGrabbedHandleReleased(mouse):
+    MouseState &= ~MouseState.Pressed;
+    MouseState &= ~MouseState.PressedOutside;
+    
+    if (!MouseHoldRepeat && MouseState.HasFlag(MouseState.In))
+        // Convert Released → Clicked for command invocation
+        mouse.Flags = LeftButtonReleased → LeftButtonClicked;
+```
+
+##### 5.3c: Clicked Event
+```csharp
+WhenGrabbedHandleClicked(mouse):
+    if (App.Mouse.MouseGrabView == this && mouse.IsSingleClicked)
+        App.Mouse.UngrabMouse();
+        // Return true if mouse outside viewport (cancel click)
+        return !Viewport.Contains(mouse.Position);
+```
+
+#### 5.4: Convert Flags for Command Binding
+```csharp
+// MouseBindings bind to Clicked events, but driver sends Pressed
+// Convert Pressed → Clicked for binding lookup
+ConvertPressedToClicked(mouse):
+    LeftButtonPressed  → LeftButtonClicked
+    MiddleButtonPressed  → MiddleButtonClicked
+    RightButtonPressed  → RightButtonClicked
+    Button4Pressed  → Button4Clicked
+```
+
+#### 5.5: Invoke Commands via MouseBindings
+```csharp
+RaiseCommandsBoundToButtonClickedFlags(mouse):
+    ConvertPressedToClicked(mouse);
+    InvokeCommandsBoundToMouse(mouse);
+
+InvokeCommandsBoundToMouse(mouse):
+    if (MouseBindings.TryGet(mouse.Flags, out binding))
+        binding.MouseEventArgs = mouse;
+        InvokeCommands(binding.Commands, binding);
+```
+
+**Default Bindings** (from `SetupMouse()`):
+```csharp
+MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Activate);
+MouseBindings.Add(MouseFlags.MiddleButtonClicked, Command.Activate);
+MouseBindings.Add(MouseFlags.RightButtonClicked, Command.Context);
+MouseBindings.Add(MouseFlags.Button4Clicked, Command.Activate);
+MouseBindings.Add(MouseFlags.LeftButtonClicked | MouseFlags.ButtonCtrl, Command.Context);
+```
+
+#### 5.6: Command Execution
+See [Command Deep Dive](command.md) for details on command execution flow.
+
+**Example: LeftButtonClicked → Command.Activate:**
+```csharp
+InvokeCommand(Command.Activate, context):
+    RaiseActivating(context):
+        OnActivating(args) || args.Cancel  // Subclass override
+        Activating?.Invoke(this, args)     // Event subscribers
+        if (!args.Cancel && CanFocus) SetFocus();
+```
+
+### Stage 6: Continuous Button Press (Optional)
+
+**Location:** `Terminal.Gui/ViewBase/MouseHoldRepeate.cs`
+
+**Enabled When:** `View.MouseHoldRepeat == true`
+
+**Behavior:**
+1. On button press → Start timer (500ms initial delay)
+2. Timer ticks → Raise `MouseIsHeldDownTick` event (50ms interval, 0.5 acceleration)
+3. View handles tick → Invoke commands again
+4. On button release → Stop timer
+
+**Use Cases:**
+- Scrollbar arrows (scroll while held)
+- Spin buttons (increment while held)
+- Any UI that should repeat action while mouse button held
+
+**Code Flow:**
+```csharp
+NewMouseEvent(mouse):
+    if (MouseHoldRepeat)
+        if (mouse.IsPressed)
+            MouseHoldRepeater.Start(mouse);
+            MouseHoldRepeater.MouseIsHeldDownTick += (s, e) => 
+                RaiseCommandsBoundToButtonClickedFlags(e.NewValue);
+        else
+            MouseHoldRepeater.Stop();
+```
+
+### Key Design Decisions & Current Limitations
+
+#### Coordinates Through the Pipeline
+1. **ANSI**: 1-based (1,1 = top-left)
+2. **AnsiMouseParser**: Converts to 0-based screen coordinates
+3. **MouseImpl**: Screen coordinates (0,0 = top-left of terminal)
+4. **View**: Viewport-relative coordinates (0,0 = top-left of view's Viewport)
+
+#### Mouse Grab Semantics
+- **Automatic**: Views with `MouseHighlightStates` or `MouseHoldRepeat` auto-grab on press
+- **Manual**: Views can call `App.Mouse.GrabMouse(this)` explicitly
+- **Ungrab**: Automatic on clicked, or manual via `App.Mouse.UngrabMouse()`
+- **Grabbed view receives ALL events** until ungrabbed, even if mouse outside viewport
+
+#### Pressed vs. Clicked Conversion
+**Problem:** Drivers emit `Pressed` and `Released`, but MouseBindings expect `Clicked`
+
+**Current Solution:** `ConvertPressedToClicked()` in `View.NewMouseEvent()`
+- Converts `LeftButtonPressed` → `LeftButtonClicked` before binding lookup
+- **Only for grabbed views** or when mouse is released inside viewport
+
+**Limitation:** This is confusing and error-prone. See recommendations below.
+
+#### Click Synthesis Timing
+**Current Bug:** MouseInterpreter defers click events by 500ms to detect double-clicks
+- This causes 500ms delay for single clicks - **UNACCEPTABLE UX**
+- See [Issue #4471](https://github.com/gui-cs/Terminal.Gui/issues/4471)
+
+**OS Behavior:** Clicks are emitted immediately; applications handle timing
+- Single click → Immediate feedback
+- Double click → Application sees second click and acts differently
+
+### Input Processing Architecture
+
+Terminal.Gui uses a layered input processing architecture:
+
+1. **Platform Input Capture** - Platform-specific APIs capture raw input events
+2. **InputProcessorImpl** - Base class that coordinates input processing using specialized parsers
+3. **AnsiResponseParser** - Parses ANSI escape sequences from the input stream
+4. **MouseInterpreter** - Generates synthetic click events from press/release pairs
+5. **AnsiMouseParser** - Parses ANSI mouse escape sequences into `Mouse` events
+
+### Platform-Specific Input Processors
+
+Different platforms use specialized input processors that inherit from `InputProcessorImpl<TInputRecord>`:
+
+* **WindowsInputProcessor** - Processes `WindowsConsole.InputRecord` structures from the Windows Console API (`ReadConsoleInput()`). Converts Windows mouse events directly to `Mouse` instances.
+* **ANSI-based Processors** - For Unix/Linux and other ANSI-compatible terminals, input is processed through ANSI escape sequence parsing.
+
+### Mouse Event Generation
+
+Mouse events are generated through a two-stage process:
+
+1. **Raw Event Capture**: Platform APIs capture basic press/release/movement events
+2. **Click Synthesis**: The `MouseInterpreter` analyzes press/release timing and position to generate single, double, and triple click events
+
+### ANSI Mouse Parsing
+
+For terminals that use ANSI escape sequences for mouse input (most modern terminals), the `AnsiMouseParser` handles:
+
+- **SGR Extended Mode** (`ESC[&lt;button;x;yM/m`) - Standard format for mouse events
+- **Button States** - Press/release detection with button codes 0-3 for left/middle/right/fourth buttons
+- **Modifiers** - Alt/Ctrl/Shift detection through extended button codes
+- **Wheel Events** - Button codes 64-65 for vertical scrolling, 68-69 for horizontal
+- **Motion Events** - Button codes 32-63 for drag operations and mouse movement
+
+### Event Flow
+
+```
+Platform API → InputProcessorImpl → AnsiResponseParser → MouseInterpreter → Application
+     ↓              ↓                        ↓                    ↓
+Raw Events    ANSI Parsing           Mouse Parsing      Click Synthesis
+```
+
+This architecture ensures consistent mouse behavior across all supported platforms while maintaining platform-specific optimizations where available.
+
+### Recommended Pipeline Improvements
+
+Based on the pipeline analysis above, here are recommended changes (backwards compatibility not required):
+
+#### 1. **Fix Click Synthesis Timing** (Critical - UX Issue)
+**Problem:** MouseInterpreter defers clicks by 500ms to detect double-clicks
+
+**Solution:** Emit clicks immediately, like OSes do
+```csharp
+// MouseInterpreter should emit:
+Press   → LeftButtonPressed   (immediate)
+Release → LeftButtonReleased  (immediate)
+        → LeftButtonClicked   (immediate after release)
+
+// If second click within threshold:
+Press   → LeftButtonPressed
+Release → LeftButtonReleased
+        → LeftButtonDoubleClicked  (NOT LeftButtonClicked!)
+```
+
+**Impact:** 
+- Single clicks feel instant (no 500ms delay)
+- Applications track timing themselves (see ListView example in mouse.md)
+- Matches OS behavior
+
+#### 2. **Simplify Pressed/Clicked Conversion**
+**Problem:** Confusing logic to convert `Pressed` → `Clicked` in multiple places
+
+**Option A: Driver emits Clicked** (Recommended)
+```csharp
+// MouseInterpreter already tracks press/release pairs
+// Just emit Clicked instead of maintaining separate flags
+Press → LeftButtonPressed (immediate, for drag/grab detection)
+Release → LeftButtonClicked (immediate, for command binding)
+```
+
+**Option B: MouseBindings accept Pressed**
+```csharp
+// Change default bindings to use Pressed instead of Clicked
+MouseBindings.Add(MouseFlags.LeftButtonPressed, Command.Activate);
+// Remove ConvertPressedToClicked logic
+```
+
+**Recommendation:** Option A - matches user mental model ("clicked" = press + release)
+
+#### 3. **Clarify Mouse Grab Lifecycle**
+**Problem:** Grab logic split across MouseImpl and View makes it hard to understand
+
+**Solution:** Document the state machine clearly
+```csharp
+// View.NewMouseEvent should have clear sections:
+// 1. Pre-conditions
+// 2. Low-level event (MouseEvent)
+// 3. GRAB HANDLING (if MouseHighlightStates or MouseHoldRepeat):
+//    a. On Pressed: Grab, set focus, update MouseState
+//    b. On Released: Convert to Clicked, update MouseState  
+//    c. On Clicked: Ungrab
+// 4. Command invocation (for Clicked/Wheel)
+```
+
+**Add to documentation:**
+- When grab happens (automatically vs manual)
+- What grabbed view receives (all events, converted coordinates)
+- When ungrab happens (clicked vs manual)
+- How MouseHoldRepeat affects grab
+
+#### 4. **Unify Coordinate Conversion**
+**Problem:** Coordinate conversion happens in multiple places
+
+**Solution:** Centralize in MouseImpl
+```csharp
+// MouseImpl.RaiseMouseEvent already does:
+Point viewportLocation = view.ScreenToViewport(mouse.ScreenPosition);
+
+// Make this THE ONLY place coordinates are converted
+// Document: "mouse.Position is ALWAYS viewport-relative when it reaches View"
+```
+
+#### 5. **Separate Press/Release from Click in MouseFlags**
+**Problem:** `LeftButtonPressed` and `LeftButtonClicked` are both present, causing confusion
+
+**Proposed Flag Reorganization:**
+```csharp
+// Raw events (from driver, immediate):
+LeftButtonPressed   // Button went down
+LeftButtonReleased  // Button came up
+
+// Synthetic events (from MouseInterpreter, after release):
+LeftButtonClicked        // Press + Release in same location
+LeftButtonDoubleClicked  // Second click within threshold
+LeftButtonTripleClicked  // Third click within threshold
+
+// Current state:
+LeftButtonDown      // Button is currently down (for drag detection)
+
+// Remove: LeftButtonPressed used for both "event" and "state" - confusing!
+```
+
+**Benefits:**
+- Clear separation of "what happened" vs "current state"
+- Easier to understand when to use each flag
+- Matches OS event models
+
+#### 6. **Document the "Why" of Each Stage**
+Add to each stage in pipeline docs:
+- **Purpose:** What problem does this stage solve?
+- **Input:** What does it receive?
+- **Output:** What does it emit?
+- **State:** What state does it maintain?
+- **Decisions:** What choices does it make?
+
+**Example for MouseInterpreter:**
+```markdown
+**Purpose:** Synthesize high-level click events from low-level press/release pairs
+
+**Input:** Raw Press/Release events from driver
+
+**Output:** 
+- Pass through: Pressed, Released, Motion, Wheel (immediate)
+- Synthesized: Clicked, DoubleClicked, TripleClicked (immediate after release)
+
+**State:** Tracks last click time, position, button for multi-click detection
+
+**Decisions:**
+- Is this release part of a click? (same position as press)
+- Is this click part of a multi-click? (timing + position + button match)
+```
+
+#### 7. **Add Pipeline Trace Logging**
+```csharp
+// At each stage, log the transformation:
+Logging.Trace($"[AnsiParser] {ansiString} → {mouse.Flags} at {mouse.ScreenPosition}");
+Logging.Trace($"[MouseInterpreter] {inputFlags} → {outputFlags}");
+Logging.Trace($"[MouseImpl] Screen {screenPos} → View {viewPos} on {view.Id}");
+Logging.Trace($"[View] {mouse.Flags} → Command.{command}");
+```
+
+**Benefits:**
+- Easy debugging of "why didn't my click work?"
+- Understand pipeline transformations
+- Validate coordinate conversions
+
+#### 8. **Align with Command System Design**
+**From command.md:** 
+- `Command.Activate` = Interaction/Selection (single click on ListView)
+- `Command.Accept` = Confirmation/Action (double-click or Enter)
+
+**Pipeline should support:**
+```csharp
+// ListView example from mouse.md tables:
+First click:   LeftButtonClicked → Command.Activate (select item)
+Second click:  LeftButtonClicked → Command.Activate (still!)
+               BUT ListView tracks timing and invokes Command.Accept itself
+
+// Default MouseBindings should be:
+MouseBindings.Add(MouseFlags.LeftButtonClicked, Command.Activate);
+MouseBindings.Add(MouseFlags.LeftButtonDoubleClicked, Command.Accept);  // NEW!
+
+// Then Button handles:
+Command.Accept → Button action (matches single click)
+Command.Activate → Set focus (do nothing else)
+
+// ListView handles:
+Command.Activate → Select item (first click) OR invoke Accept (second click)
+Command.Accept → Open item (from DoubleClicked or Enter key)
+```
+
+**Benefits:**
+- Consistent with documented behavior in mouse.md
+- Applications don't need custom timing logic
+- Framework provides DoubleClicked flag for "accept" actions
+
+#### Summary of Pipeline Changes
+
+| Stage | Current Behavior | Recommended Change | Impact |
+|-------|-----------------|-------------------|---------|
+| **MouseInterpreter** | Defers clicks 500ms | Emit clicks immediately | **Critical** - fixes UX bug |
+| **MouseInterpreter** | Emits `Clicked` 500ms after `Released` | Emit `Clicked` immediately after `Released` | Simplifies timing |
+| **View.NewMouseEvent** | Converts `Pressed`→`Clicked` in multiple places | Driver emits `Clicked`, no conversion needed | Clearer code |
+| **MouseImpl** | Coordinate conversion | Already correct, just document | Better clarity |
+| **MouseBindings** | Only `LeftButtonClicked` → `Activate` | Add `LeftButtonDoubleClicked` → `Accept` | Matches command.md design |
+| **Documentation** | Scattered | Centralized pipeline doc (this section) | Developer productivity |

+# View.NewMouseEvent Rewrite Plan
+
+**Issue**: #4474 - Remove Click Delay and Simplify Mouse Event Handling
+
+**Goal**: Rewrite `View.NewMouseEvent` to align with the mouse behavior specification, removing legacy complexity and fixing the 500ms click delay bug.
+
+**Status**: Planning Phase
+
+---
+
+## Overview
+
+The current `View.NewMouseEvent` implementation has accumulated significant technical debt marked as "LEGACY - Can be rewritten". This rewrite will:
+
+1. Remove unnecessary complexity
+2. Align with the specification's clean separation of concerns
+3. Fix bugs related to mouse grab and click handling
+4. Ensure all tests pass
+
+---
+
+## Current State Analysis
+
+### What Works (Keep)
+- Pre-condition validation (enabled, visible checks)
+- `RaiseMouseEvent` / `OnMouseEvent` / `MouseEvent` pattern (low-level handler)
+- `MouseHoldRepeater` concept (timer-based repetition for continuous press)
+- `MouseState` tracking for visual feedback
+- Command invocation via `MouseBindings`
+
+### What's Problematic (Fix)
+1. **Grab Logic Scattered**: `WhenGrabbedHandlePressed`, `WhenGrabbedHandleReleased`, `WhenGrabbedHandleClicked` mix concerns
+2. **Pressed→Clicked Conversion**: Done in multiple places (`ConvertPressedToClicked`, `ConvertReleasedToClicked`)
+3. **MouseState Updates**: Mixed into grab handlers instead of being explicit
+4. **Flow Unclear**: Hard to follow the execution path
+5. **Comments Misleading**: TODOs and questions that need answers
+
+### Dependencies
+- `MouseHoldRepeater` - Keep, but verify usage
+- `App.Mouse.GrabMouse/UngrabMouse` - Keep interface, simplify calls
+- `MouseBindings` - Keep, ensure proper integration
+- `MouseState` - Keep, clarify update points
+
+---
+
+## Architecture Principles (From Spec)
+
+### Separation of Concerns
+
+| Concern | Purpose | Implementation |
+|---------|---------|----------------|
+| **MouseState** | Visual feedback | Updated on press/release/enter/leave |
+| **Mouse Grab** | Capture all events until release | Auto-grab on press if `MouseHighlightStates` or `MouseHoldRepeat` |
+| **Commands** | Execute actions | Invoked via `MouseBindings` on clicked events |
+| **MouseHoldRepeat** | Timer-based repetition | Independent of click logic |
+
+### Key Behaviors
+
+1. **Auto-Grab**: When `MouseHighlightStates != None` OR `MouseHoldRepeat == true`
+   - Grab on first button press
+   - Ungrab on button release (clicked event)
+   - Set focus if `CanFocus`
+
+2. **MouseState Management**:
+   - `In` - Mouse over viewport (set by MouseEnter/Leave)
+   - `Pressed` - Button down while over viewport
+   - `PressedOutside` - Button down, mouse moved outside (only if `!MouseHoldRepeat`)
+
+3. **Click Conversion**:
+   - Driver emits: `Pressed`, `Released`, `Clicked` (from MouseInterpreter)
+   - View only needs to handle `Clicked` events for commands
+   - Pressed/Released are for grab lifecycle
+
+4. **Command Invocation**:
+   - `Clicked` events → `Command.Accept` (default binding)
+   - `Pressed` events → `Command.Activate` (current default, may need review)
+   - Wheel events → bound commands
+
+---
+
+## Rewrite Plan - Phased Approach
+
+### Phase 1: Preparation & Analysis ✅
+**Goal**: Understand current behavior, identify all tests
+
+**Tasks**:
+- [x] Review specification documents
+- [x] Analyze current `View.NewMouseEvent` implementation
+- [x] Identify all tests marked `Skip = "Broken in #4474"`
+- [x] Create this plan document
+- [x] Run all tests to establish baseline
+- [x] Document baseline test results
+
+**Deliverables**:
+- This plan document
+- Baseline test results: **382 tests passing, 23 tests skipped**
+- List of all affected tests
+
+**Baseline Results**:
+- UnitTestsParallelizable/ViewBase/Mouse/MouseTests.cs: 3 skipped tests
+- Total across all projects: 23 skipped tests marked with `Skip = "Broken in #4474"`
+- All other mouse tests passing
+
+### Phase 2: Simplify Mouse Grab Logic ✅
+**Goal**: Consolidate scattered grab logic into clear, linear flow
+
+**Tasks**:
+- [x] Extract `ShouldAutoGrab` property: `MouseHighlightStates != None || MouseHoldRepeat`
+- [x] Create `HandleAutoGrabPress(mouse)`: Grab, set focus, update MouseState
+- [x] Create `HandleAutoGrabRelease(mouse)`: Update MouseState only
+- [x] Create `HandleAutoGrabClicked(mouse)`: Ungrab
+- [x] Create `UpdateMouseStateOnPress(position)`: Explicit state management
+- [x] Create `UpdateMouseStateOnRelease()`: Explicit state management
+- [x] Update `NewMouseEvent` to use new helpers
+- [x] Remove `WhenGrabbedHandlePressed`, `WhenGrabbedHandleReleased`, `WhenGrabbedHandleClicked`
+- [x] Run tests, verify no regressions
+
+**Results**:
+- ✅ All 382 tests still passing
+- ✅ Code is now more linear and easier to read
+- ✅ MouseState management is explicit and documented
+- ✅ Grab lifecycle is consolidated in dedicated helper methods
+- ✅ `NewMouseEvent` has clear numbered sections (1-6)
+
+**Acceptance Criteria**:
+- ✅ All grab-related tests pass
+- ✅ Focus setting tests pass
+- ✅ MouseState tests pass
+
+### Phase 3: Clean Up Click Conversion
+**Goal**: Remove redundant click conversion logic
+
+**Current Issues**:
+- `ConvertPressedToClicked()` - Should not be needed if MouseInterpreter works
+- `ConvertReleasedToClicked()` - Only used in grab release scenario
+
+**Analysis Needed**:
+- Does MouseInterpreter emit `Clicked` events immediately after `Released`?
+- If yes, remove conversion logic entirely
+- If no, fix MouseInterpreter first (separate task)
+
+**Proposed Approach**:
+```csharp
+// Option A: MouseInterpreter emits Clicked (spec says it should)
+// -> Remove all ConvertXXXToClicked methods
+// -> Bindings work with Clicked events directly
+
+// Option B: We need conversion for grab scenario
+// -> Keep only ConvertReleasedToClicked in HandleAutoGrabRelease
+// -> Document why it's needed
+```
+
+**Tasks**:
+- [ ] Verify MouseInterpreter behavior (does it emit Clicked after Released?)
+- [ ] If yes: Remove `ConvertPressedToClicked` and `ConvertReleasedToClicked`
+- [ ] If no: File bug, keep minimal conversion in grab handler
+- [ ] Update `RaiseCommandsBoundToButtonClickedFlags` to not do conversion
+- [ ] Run tests, verify command invocation still works
+
+**Acceptance Criteria**:
+- Commands are invoked correctly
+- No redundant conversions
+- Tests for Accepting/Activating pass
+
+### Phase 4: Clarify MouseState Updates
+**Goal**: Make MouseState updates explicit and obvious
+
+**Current Issues**:
+- MouseState updates scattered across grab handlers
+- Unclear when `Pressed` vs `PressedOutside` is set
+- Missing documentation
+
+**Proposed Approach**:
+```csharp
+private void UpdateMouseStateOnPress(Point position)
+{
+    if (Viewport.Contains(position))
+    {
+        if (MouseHighlightStates.HasFlag(MouseState.Pressed))
+        {
+            MouseState |= MouseState.Pressed;
+        }
+        MouseState &= ~MouseState.PressedOutside;
+    }
+    else
+    {
+        if (MouseHighlightStates.HasFlag(MouseState.PressedOutside) && !MouseHoldRepeat)
+        {
+            MouseState |= MouseState.PressedOutside;
+        }
+    }
+}
+
+private void UpdateMouseStateOnRelease()
+{
+    MouseState &= ~MouseState.Pressed;
+    MouseState &= ~MouseState.PressedOutside;
+}
+```
+
+**Tasks**:
+- [ ] Extract `UpdateMouseStateOnPress(position)` method
+- [ ] Extract `UpdateMouseStateOnRelease()` method
+- [ ] Call from appropriate points in grab handlers
+- [ ] Add XML documentation explaining each state
+- [ ] Run tests, verify visual behavior
+
+**Acceptance Criteria**:
+- MouseState changes are explicit and documented
+- Visual highlight tests pass
+- Border pressed tests pass
+
+### Phase 5: Streamline Command Invocation
+**Goal**: Ensure command invocation is clean and efficient
+
+**Current State**:
+```csharp
+RaiseCommandsBoundToButtonClickedFlags()
+  -> ConvertPressedToClicked()  // Should not be needed
+  -> InvokeCommandsBoundToMouse()
+
+RaiseCommandsBoundToWheelFlags()
+  -> InvokeCommandsBoundToMouse()
+```
+
+**Proposed Simplification**:
+```csharp
+// Only invoke commands for:
+// 1. Clicked events (single, double, triple)
+// 2. Wheel events
+// Pressed/Released are for grab lifecycle only
+```
+
+**Tasks**:
+- [ ] Review default bindings in `SetupMouse()`
+- [ ] Verify `Pressed` bindings are needed (spec says commands on `Clicked`)
+- [ ] Remove `Pressed` bindings if not needed
+- [ ] Ensure `RaiseCommandsBoundToButtonClickedFlags` only handles clicks
+- [ ] Run tests for command invocation
+
+**Acceptance Criteria**:
+- Default bindings align with spec
+- Commands invoked at correct times
+- No duplicate command invocations
+
+### Phase 6: Rewrite NewMouseEvent Method
+**Goal**: Implement clean, linear flow using helper methods from phases 2-5
+
+**Proposed Structure**:
+```csharp
+public bool? NewMouseEvent(Mouse mouse)
+{
+    // 1. Pre-conditions
+    if (!ValidatePreConditions(mouse))
+    {
+        return false;
+    }
+
+    // 2. Setup (legacy MouseHoldRepeater initialization)
+    EnsureMouseHoldRepeaterInitialized();
+
+    // 3. MouseHoldRepeat timer management
+    if (MouseHoldRepeat)
+    {
+        ManageMouseHoldRepeatTimer(mouse);
+    }
+
+    // 4. Low-level MouseEvent (cancellable)
+    if (RaiseMouseEvent(mouse) || mouse.Handled)
+    {
+        return true;
+    }
+
+    // 5. Auto-grab lifecycle
+    if (ShouldAutoGrab)
+    {
+        if (HandleAutoGrabLifecycle(mouse))
+        {
+            return mouse.Handled;
+        }
+    }
+
+    // 6. Command invocation
+    if (mouse.IsSingleDoubleOrTripleClicked)
+    {
+        return RaiseCommandsBoundToButtonClickedFlags(mouse);
+    }
+
+    if (mouse.IsWheel)
+    {
+        return RaiseCommandsBoundToWheelFlags(mouse);
+    }
+
+    return false;
+}
+```
+
+**Tasks**:
+- [ ] Implement `ValidatePreConditions(mouse)`
+- [ ] Implement `EnsureMouseHoldRepeaterInitialized()`
+- [ ] Implement `ManageMouseHoldRepeatTimer(mouse)`
+- [ ] Implement `ShouldAutoGrab` property
+- [ ] Implement `HandleAutoGrabLifecycle(mouse)` using phase 2-4 helpers
+- [ ] Update `RaiseCommandsBoundToButtonClickedFlags` (remove conversion)
+- [ ] Add comprehensive XML documentation
+- [ ] Run all tests
+
+**Acceptance Criteria**:
+- Method is easy to read and understand
+- Each section has clear purpose
+- All existing tests pass
+- No new bugs introduced
+
+### Phase 7: Fix Skipped Tests
+**Goal**: Update skipped tests to work with new implementation
+
+**Known Skipped Tests**:
+```csharp
+// Tests/UnitTestsParallelizable/ViewBase/Mouse/MouseTests.cs
+[Fact(Skip = "Broken in #4474")]
+public void MouseClick_OnSubView_RaisesSelectingEvent()
+
+[Fact(Skip = "Broken in #4474")]
+public void MouseClick_RaisesSelecting_WhenCanFocus()
+
+[Theory(Skip = "Broken in #4474")]
+public void MouseClick_SetsFocus_If_CanFocus()
+```
+
+**Tasks**:
+- [ ] Search all test projects for `Skip = "Broken in #4474"`
+- [ ] Catalog all skipped tests
+- [ ] Analyze each test's expectations
+- [ ] Update tests to match new behavior (if spec changed)
+- [ ] Fix implementation if test expectations are correct
+- [ ] Remove `Skip` attributes
+- [ ] Verify all tests pass
+
+**Acceptance Criteria**:
+- No tests marked `Skip = "Broken in #4474"`
+- All mouse-related tests pass
+- Test coverage maintained or improved
+
+### Phase 8: Add New Tests
+**Goal**: Ensure comprehensive test coverage for new implementation
+
+**Test Scenarios from Spec**:
+
+1. **Normal Button (MouseHoldRepeat = false)**
+   - [ ] Single click (press + immediate release) → 1 Accept
+   - [ ] Press and hold (2+ seconds) → 1 Accept on release
+   - [ ] Double-click → 2 Accepts with ClickCount 1, 2
+   - [ ] Triple-click → 3 Accepts with ClickCount 1, 2, 3
+
+2. **Repeat Button (MouseHoldRepeat = true)**
+   - [ ] Single click → 1 Accept
+   - [ ] Press and hold → 10+ Accepts (timer-based)
+   - [ ] Double-click → 2 Accepts (timer doesn't start)
+   - [ ] Hold then quick click → many + 1 Accept
+
+3. **MouseState Transitions**
+   - [ ] Enter → `In` flag set
+   - [ ] Press inside → `Pressed` flag set
+   - [ ] Move outside while pressed → `PressedOutside` set (if !MouseHoldRepeat)
+   - [ ] Release → flags cleared
+
+4. **Mouse Grab**
+   - [ ] Press inside → auto-grab, set focus
+   - [ ] Release inside → ungrab, invoke commands
+   - [ ] Release outside → ungrab, no commands
+
+**Tasks**:
+- [ ] Write test for each scenario
+- [ ] Use parallelizable test base class
+- [ ] Follow existing test patterns
+- [ ] Add `// CoPilot - AI Generated` comments
+- [ ] Verify all new tests pass
+
+**Acceptance Criteria**:
+- All spec scenarios have test coverage
+- Tests are parallelizable
+- Tests follow project conventions
+
+### Phase 9: Documentation & Cleanup
+**Goal**: Update documentation and remove obsolete code
+
+**Tasks**:
+- [ ] Update XML docs in `View.Mouse.cs`
+- [ ] Remove all "LEGACY" comments
+- [ ] Remove all "TODO" and "QUESTION" comments (address or file issues)
+- [ ] Update `mouse.md` if behavior changed
+- [ ] Update `mouse-behavior-specification.md` to mark implemented
+- [ ] Add code examples to documentation
+- [ ] Run spell check on comments
+
+**Acceptance Criteria**:
+- No "LEGACY" comments remain
+- All TODOs addressed or converted to issues
+- Documentation is accurate and helpful
+- Examples compile and run
+
+### Phase 10: Final Validation
+**Goal**: Ensure everything works end-to-end
+
+**Tasks**:
+- [ ] Run all unit tests (UnitTests + UnitTestsParallelizable)
+- [ ] Run all integration tests
+- [ ] Run UICatalog, test mouse behavior manually
+- [ ] Test Button scenarios from spec
+- [ ] Test ListView scenarios from spec
+- [ ] Test Dialog/MessageBox scenarios
+- [ ] Check for performance regressions
+- [ ] Run with different terminals (if applicable)
+
+**Acceptance Criteria**:
+- All tests pass (100%)
+- No performance regressions
+- UICatalog behaves correctly
+- No unexpected visual changes
+
+---
+
+## Success Criteria
+
+### Must Have
+- [x] All existing tests pass (baseline established)
+- [ ] All skipped tests fixed and passing
+- [ ] `NewMouseEvent` is clear and maintainable
+- [ ] Grab logic is consolidated
+- [ ] MouseState updates are explicit
+- [ ] Command invocation is clean
+- [ ] Comprehensive test coverage
+
+### Nice to Have
+- [ ] Improved performance
+- [ ] Better XML documentation
+- [ ] Code examples in docs
+- [ ] Reduced code complexity metrics
+
+### Risks & Mitigation
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| Breaking existing behavior | High | Phased approach, run tests after each change |
+| MouseInterpreter needs changes | Medium | Verify early, coordinate changes |
+| Tests are wrong, not code | Medium | Review spec carefully, discuss with team |
+| Performance regression | Low | Benchmark critical paths |
+
+---
+
+## Notes

+- **Coding Standards**: Follow CONTRIBUTING.md strictly
+  - Use explicit types (no `var` except built-ins)
+  - Use target-typed `new ()`
+  - Format with ReSharper
+  - Add XML docs to public APIs
+
+- **Testing Strategy**:
+  - Run tests after each phase
+  - Fix failures immediately
+  - Don't accumulate technical debt
+
+- **Communication**:
+  - Update this plan as work progresses
+  - Mark completed phases with ✅
+  - Document decisions and rationale

+
+## Appendix: Code Patterns
+
+### Helper Method Pattern
+```csharp
+/// <summary>
+/// Brief description.
+/// </summary>
+/// <param name="paramName">Description.</param>
+/// <returns>Description.</returns>
+private bool HelperMethod(Mouse mouse)
+{
+    // Implementation
+    return false;
+}
+```
+
+### Property Pattern
+```csharp
+/// <summary>
+/// Gets whether auto-grab should be enabled for this view.
+/// </summary>
+private bool ShouldAutoGrab => MouseHighlightStates != MouseState.None || MouseHoldRepeat;
+```
+
+### Test Pattern
+```csharp
+// CoPilot - AI Generated
+[Fact]
+public void NewMouseEvent_Press_AutoGrabs_WhenMouseHighlightStatesSet()
+{
+    // Arrange
+    View view = new ()
+    {
+        Width = 10,
+        Height = 10,
+        MouseHighlightStates = MouseState.Pressed
+    };
+
+    // Act
+    view.NewMouseEvent(new ()
+    {
+        Position = new (5, 5),
+        Flags = MouseFlags.LeftButtonPressed
+    });
+
+    // Assert
+    Assert.Equal(view, view.App?.Mouse.MouseGrabView);
+}
+```

+# Terminal.Gui Driver Input/Output Analysis
+
+This document provides a comprehensive analysis of how the four Terminal.Gui drivers (WindowsDriver, UnixDriver, DotNetDriver, and FakeDriver) handle keyboard and mouse input, including native/platform APIs and ANSI infrastructure usage.
+
+## Table of Contents
+
+- [Architecture Overview](#architecture-overview)
+- [WindowsDriver](#windowsdriver)
+- [UnixDriver](#unixdriver)
+- [DotNetDriver](#dotnetdriver)
+- [FakeDriver](#fakedriver)
+- [ANSI Infrastructure](#ansi-infrastructure)
+- [Comparison Table](#comparison-table)
+
+---
+
+## Architecture Overview
+
+All four drivers follow the same component-based architecture:
+
+```
+???????????????????????????????????????????????????????????
+?                  ComponentFactory<T>                    ?
+?  - Creates driver-specific components                   ?
+?  - T = input record type (varies by platform)           ?
+???????????????????????????????????????????????????????????
+                     ?
+        ??????????????????????????????????????????
+        ?            ?            ?              ?
+   ???????????  ?????????  ??????????????  ??????????
+   ? IInput  ?  ?IOutput?  ?IInputProc. ?  ?ISizeMon?
+   ?   <T>   ?  ?       ?  ?            ?  ?        ?
+   ???????????  ?????????  ??????????????  ??????????
+```
+
+### Common Input Pipeline
+
+1. **IInput\<T\>** (input thread) ? reads raw input ? queues to `ConcurrentQueue<T>`
+2. **IInputProcessor** (main thread) ? dequeues ? processes through `AnsiResponseParser<T>`
+3. **KeyConverter** ? converts platform-specific input to Terminal.Gui `Key` events
+4. **Events raised** ? `KeyDown`, `KeyUp`, `MouseEvent`
+
+### Generic Type Parameter `<T>` by Driver
+
+- **WindowsDriver**: `WindowsConsole.InputRecord` (struct containing keyboard/mouse events)
+- **UnixDriver**: `char` (raw character stream)
+- **DotNetDriver**: `ConsoleKeyInfo` (managed .NET keyboard info)
+- **FakeDriver**: `ConsoleKeyInfo` (for test compatibility)
+
+---
+
+## WindowsDriver
+
+### Native APIs Used
+
+#### Keyboard Input
+- **Windows Console API** (via P/Invoke to `kernel32.dll`):
+  - `ReadConsoleInputW` - Reads input events from console input buffer
+  - `PeekConsoleInputW` - Checks if input is available without consuming it
+  - `GetStdHandle(STD_INPUT_HANDLE)` - Gets standard input handle
+  - `GetConsoleMode` / `SetConsoleMode` - Configure console input modes
+  - `FlushConsoleInputBuffer` - Clears pending input
+
+**Console Modes Enabled**:
+```csharp
+ENABLE_MOUSE_INPUT          // Enable mouse input events
+ENABLE_EXTENDED_FLAGS       // Enable extended flags
+ENABLE_VIRTUAL_TERMINAL_INPUT // Enable ANSI escape sequence processing
+```
+
+**Console Modes Disabled**:
+```csharp
+ENABLE_QUICK_EDIT_MODE     // Disable quick edit (interferes with mouse)
+ENABLE_PROCESSED_INPUT     // Disable Ctrl+C handling
+```
+
+#### Mouse Input
+- **Native via InputRecord.MouseEvent**:
+  - Direct mouse events from Windows Console API
+  - `MouseEventRecord` contains:
+    - `MousePosition` (Coord)
+    - `ButtonState` (Button1-4, RightmostButton)
+    - `ControlKeyState` (Shift, Alt, Ctrl)
+    - `EventFlags` (MouseMoved, DoubleClick, MouseWheeled, MouseHorizontalWheeled)
+
+#### Keyboard Output
+- **Windows Console API**:
+  - `WriteConsoleW` - Writes Unicode text directly to console
+  - `SetConsoleTextAttribute` - Sets foreground/background colors (legacy mode)
+  - `SetConsoleCursorPosition` - Positions cursor
+  - `SetConsoleCursorInfo` - Sets cursor visibility and size
+  - `CreateConsoleScreenBuffer` - Creates alternate screen buffer (legacy mode)
+  - `SetConsoleActiveScreenBuffer` - Switches active buffer
+
+**Two Output Modes**:
+1. **Legacy Console Mode** (`IsLegacyConsole = true`):
+   - Uses Windows Console API functions directly
+   - Uses `SetConsoleTextAttribute` for colors
+   - Creates separate screen buffer with `CreateConsoleScreenBuffer`
+   - No ANSI escape sequences
+
+2. **VT Mode** (`IsLegacyConsole = false`):
+   - Uses ANSI escape sequences via `WriteConsoleW`
+   - Enables `ENABLE_VIRTUAL_TERMINAL_PROCESSING`
+   - Uses alternative screen buffer with ANSI codes
+   - Supports TrueColor via RGB ANSI sequences
+
+### Input Processing Components
+
+**WindowsInput** (`IInput<InputRecord>`):
+- Reads: `InputRecord` structs via `ReadConsoleInputW`
+- Filters: Only processes `EventType.Key` and `EventType.Mouse`
+- Threading: Runs on dedicated input thread
+
+**WindowsInputProcessor** (`InputProcessorImpl<InputRecord>`):
+- Converts: `InputRecord` ? `Key` or `Mouse` events
+- Uses: `WindowsKeyConverter` for keyboard translation
+- Mouse: Directly converts `MouseEventRecord` to `Mouse` (no ANSI parsing needed)
+- Keyboard: Processes through `AnsiResponseParser<InputRecord>` (for consistency)
+
+**WindowsKeyConverter** (`IKeyConverter<InputRecord>`):
+- Handles VK_PACKET for IME/Unicode input
+- Uses `WindowsKeyHelper.MapKey()` for key mapping
+- Converts Windows `ControlKeyState` to Terminal.Gui modifiers
+- Provides round-trip conversion (`Key` ? `InputRecord`)
+
+### ANSI Infrastructure Usage
+
+**Used**:
+- ? `EscSeqUtils.CSI_*` - For ANSI output in VT mode
+- ? `AnsiResponseParser<InputRecord>` - For keyboard processing consistency
+- ? Alternative screen buffer control (ANSI mode only)
+- ? Mouse event ANSI codes (NOT used for input, only output in rare cases)
+
+**Not Used**:

+// Control flags enabled:
+CS8        // 8-bit characters
+```
+

+
+---
+
+## ANSI Infrastructure
+
+### Core Components
+
+#### AnsiResponseParser\<T\>
+
+**Purpose**: Parses ANSI escape sequences from input stream.

+- Required for hover effects and mouse-based drawing
+
+**Mode 1006** (SGR Extended Mouse):
+- Modern format: `ESC[<button;x;y{M|m}`
+- Supports unlimited coordinates (decimal)
+- Distinguishes press (M) from release (m)
+
+**Mode 1015** (URXVT Extended Mouse):

+## Key Findings
+
+### Windows Driver Uniqueness
+- **Only driver** with native mouse event support (no ANSI parsing needed)
+- **Dual-mode operation**: Automatically detects and adapts to legacy vs VT consoles
+- **Most complex** native API usage (CreateConsoleScreenBuffer, multiple P/Invoke calls)
+- **Best native Windows integration** (respects VS Debug Console, keyboard layout)
+
+### Unix Driver Characteristics
+- **Most dependent on ANSI infrastructure** (mouse and keyboard both require parsing)
+- **Lowest-level input** (raw byte stream, manual UTF-8 decoding)
+- **Most complex terminal setup** (raw mode with many flags)
+- **Best Unix integration** (direct libc calls, platform-specific ioctl constants)
+
+### DotNet Driver Role
+- **Best cross-platform compatibility** (works everywhere .NET works)
+- **Simplest API surface** (managed .NET Console API)
+- **Hybrid approach**: Uses NetWinVTConsole on Windows for VT enablement
+- **Good fallback driver** when platform-specific drivers unavailable
+
+### Fake Driver Purpose
+- **Zero native APIs** (pure simulation)
+- **Test infrastructure** (input injection, output capture)
+- **Timing control** (uses Application.Invoke for mouse event deferral)
+- **Verification support** (peek call counting, buffer inspection)
+
+### ANSI Infrastructure Importance
+- **Critical for Unix/DotNet**: All mouse input comes through ANSI escape sequences
+- **Optional for Windows**: Native APIs provide direct event access
+- **Universal for output**: All drivers use ANSI codes for colors/styles (except Windows legacy mode)
+- **Coordinated by InputProcessorImpl**: Generic `AnsiResponseParser<T>` works with all input types
+
+---
+
+## Summary
+
+The four Terminal.Gui drivers showcase different approaches to console I/O:
+
+1. **WindowsDriver** leverages Windows Console API for direct, high-performance access to keyboard and mouse events, with intelligent dual-mode operation for legacy and modern consoles.
+
+2. **UnixDriver** embraces raw terminal control via POSIX APIs, relying heavily on ANSI escape sequences for all mouse input and many keyboard sequences.
+
+3. **DotNetDriver** prioritizes cross-platform compatibility using managed .NET APIs, with Windows VT enablement for enhanced functionality.
+
+4. **FakeDriver** provides a pure simulation environment for testing, with no actual console I/O but faithful emulation of input/output behavior.
+
+The **ANSI infrastructure** (`AnsiResponseParser`, `AnsiMouseParser`, `EscSeqUtils`) is the glue that enables cross-platform consistency, being critical for Unix/DotNet drivers and beneficial for Windows/Fake drivers. All drivers share the same processing pipeline through `InputProcessorImpl<T>`, with the generic type parameter allowing each driver to work with its native input format while maintaining a unified event model.
