On KeyDown Bug

Hmmm, I guess I am not sure why you would use 'switch' without a
switchExpression (according to the docs).  Seems to me that you are tempting
fate and the switch structure to decipher what you want.

You could try
on keyUp theKey
  local theModifier
  put "" into theModifier
  put "Opt Cmd Shft Ctrl" into keyStr
  put (the optionKey is down) && (the CommandKey is down) && \
      (the shiftKey is down)&& (the controlKey is down) into mods
  repeat with x = 1 to the number of words in mods
    if (word x of mods) then put word x of keyStr & "-" after theModifier
  end repeat
  delete last char of theModifier
  put theModifier && theKey
  pass keyUp
end keyUp
--this work, sort of, but not in all cases.  Please read the following:

The keydown message is not the only one you need to consider.
Suggestion: turn on the Message Watcher (in the Development menu)
and note the messages passed with different key presses, especially the
keyUp+optionKeyDown+controlKeyDown+rawKeyDown

Hope this helps.
