calling handlers with keys

[Yennie at aol.com]

I'm not sure this is the simplest way, but it should work if you have to look 
for keydowns inside of a long-running loop:

(note: I've never used the "with messages" syntax, but I believe this is how 
it works)

on keyDown theKey
  global lastKey
  put theKey into lastKey
end keyDown

on mainLoop
  global lastKey
  repeat
    presentSomeObjects 
    wait 1 with messages -- this should let your keyDowns get through once 
per loop
    switch (lastKey)
      -- process the key
    end switch
    put empty into lastKey
  end repeat
end mainLoop
