 *	keyboard. Those constants with "ANSI" in the name are labeled
 *	according to the key position on an ANSI-standard US keyboard.
 *	For example, kVK_ANSI_A indicates the virtual keycode for the key
 *	with the letter 'A' in the US keyboard layout. Other keyboard
 *	layouts may have the 'A' key label on a different physical key;
 *	in this case, pressing 'A' will generate a different virtual
 *	keycode.
