Is there any easy way to do keyboard short cuts with tkmenubar /
tkmenu, etc? (short cuts in the vein of Alt+F makes the file drop
down, and then alt+O would do open in the file menu).

I can do this I think if I could find out how to be notified when the
TkMenu item disappears (from a click or keystroke somewhere...)... but
also if there's an easier way, that would be nice.

Thanks for any help you can give
