On my Macintosh, at least, this stack does not do its stuff when I press
any of the modifier keys (Ctrl, Alt, Command).

The OS does not report to applications when only a modifier key is pressed. (It's a little better on Windows for a few keys I think.) The OS only sends a message after the accompanying alpha key is pressed. This also applies to "commandkeydown" and other similar system messages, they only trigger after the second key is pressed.

The alt key is "optionKeydown", but again, you'll only get the message after the second key is pressed. The OS doesn't send a message for shift at all, because that key instead causes a different numeric parameter to be sent.
