I think what Richmond was after was a message that get's sent when he 
presses the shift key, not detecting when it's down.  The only way that 
comes to mind would be a front script that captured the keydown/keyup or 
rawkeys messages, check for the shift key state then fired a message to 
a handler of your choosing.

You'd have to pass on the original event in either case and make sure 
you didn't set up some sort of infinite loop though.
