MENU_SHORTCUT_MASK

public static final int MENU_SHORTCUT_MASK

The platform-appropriate modifier mask for menu shortcuts.

• Windows/Linux: InputEvent.CTRL_DOWN_MASK (Control key)
• macOS: InputEvent.META_DOWN_MASK (Command key)

Use this constant instead of hardcoding InputEvent.CTRL_DOWN_MASK to provide native keyboard shortcuts on each platform. For example, shortcuts using this mask will appear as Ctrl+F on Windows/Linux and ⌘+F on macOS.
