NativeApplication.nativeApplication.addEventListener (KeyboardEvent.KEY_DOWN, nativeApplication_keyDown);
NativeApplication.nativeApplication.addEventListener (KeyboardEvent.KEY_UP, nativeApplication_keyUp);
private function nativeApplication_keyUp(e: KeyboardEvent): void
{
	switch (e.keyCode)
	{
		case Keyboard.BACK:
			e.preventDefault ();
			trace ("Keyboard", "back button");
			break;
		case Keyboard.MENU:
			e.preventDefault ();
			trace ("Keyboard", "menu button");
			break;
		case Keyboard.SEARCH:
			e.preventDefault ();
			trace ("Keyboard", "search button");
			break;
		default:
	}
}
 
private function nativeApplication_keyDown(e: KeyboardEvent): void
{
	switch (e.keyCode)
	{
		case Keyboard.BACK:
		case Keyboard.MENU:
		case Keyboard.SEARCH:
			e.preventDefault ();
					break;
		default:
	}
}
