62  *  Summary:
63  *    Virtual keycodes
64  *  
65  *  Discussion:
66  *    These constants are the virtual keycodes defined originally in
67  *    Inside Mac Volume V, pg. V-191. They identify physical keys on a
68  *    keyboard. Those constants with "ANSI" in the name are labeled
69  *    according to the key position on an ANSI-standard US keyboard.
70  *    For example, kVK_ANSI_A indicates the virtual keycode for the key
71  *    with the letter 'A' in the US keyboard layout. Other keyboard
72  *    layouts may have the 'A' key label on a different physical key;
73  *    in this case, pressing 'A' will generate a different virtual
74  *    keycode.
