[plt-scheme] Fwd: Key strokes in BigBang

Hi all,

A student sent me the message below.  My reply was that I'm confident there
isn't a way to handle Alt- and Ctrl-modified keystrokes in universe, but that
Shift can be detected since it affects the character returned as the
key-event.

I'm sending this to you all just in case I'm mistaken.  If there's a way to
detect Ctrl/Alt, please let me know.

Best,
jmj

Is there a way for big bang key-events to be more than one key? For example,
having "control-a" do something different in big bang, then say just "a". I
was wondering whether I could do this for in my game, for lighting up the
maze with something less obvious then "l".
