name	avalonia-input-and-commands
description	Implement or debug Avalonia routed input, focus management, keyboard navigation, commands, gestures, drag/drop workflows, text editing behavior, and interaction routing. Use for `ICommand`, `KeyBinding`, routed events, focus bugs, drag/drop, scroll interaction, or text input edge cases.

Avalonia Input and Commands

Start with:

• ../../references/18-input-system-and-routed-events.md
• ../../references/19-focus-and-keyboard-navigation.md
• ../../references/24-commands-hotkeys-and-gestures.md

Load these when the interaction surface needs them:

• ../../references/34-dragdrop-workflows.md
• ../../references/57-scrollviewer-offset-anchoring-and-snap-points.md
• ../../references/58-textbox-editing-clipboard-undo-and-input-options.md
• ../../references/36-adorners-focus-and-overlay-layers.md

Workflow

1. Decide whether the interaction belongs in routed events, commands, or control state.
2. Keep focus order, key handling, and command routing explicit.
3. Model drag/drop and text-editing behavior as part of the interaction contract, not as incidental details.
4. Validate pointer, keyboard, and programmatic interaction paths separately.

Rules

• Prefer command and state dispatch over large event-handler trees.
• Keep access-key, focus, and keyboard-navigation rules testable.
• Treat text editing and drag/drop as behavior with edge cases, not cosmetic features.
