Pierre, et al:

While my example will work for the specific key, "T", the preferred form
for generalized control would probably be some variation on a switch.   I
have yet to use this structure, so forgive me (and let me know) if my
syntax is not correct:

	on controKeyDown zaKey
		switch zaKey
			case "T"
				doSomething
			case "U"
				deSomethingElse
				pass controlKeyDown
			case "V"
				beep  -- block ctrl-V with audio warning
			case "W"
				doYetSomethingElse
			default
				pass controlKeyDown
		end switch
	end controlKeyDown

Note: The second line in case U assumes a handler higher in the message
hierarchy must also act on the same keystroke
