NodeFlowShortcutManager<T> class

Manages keyboard shortcuts and action execution.

The shortcut manager maintains:

• Registered actions that can be executed
• Keyboard shortcut mappings to action IDs
• Methods for handling keyboard events
• Action search and categorization

Built-in shortcuts follow platform conventions:

• Cmd/Ctrl for primary modifier
• Shift for variations
• Common key bindings (Cmd+A for select all, Delete for delete, etc.)

Example usage:

// Create manager and register actions
final manager = NodeFlowShortcutManager<MyData>();
manager.registerActions(DefaultNodeFlowActions.createDefaultActions());

// Handle keyboard events
KeyboardListener(
  onKeyEvent: (event) {
    manager.handleKeyEvent(event, controller, context);
  },
  child: ...,
);

// Custom shortcut
manager.setShortcut(
  LogicalKeySet(LogicalKeyboardKey.keyQ, LogicalKeyboardKey.meta),
  'my_custom_action',
);

// Search actions
final results = manager.searchActions('select');
