How about something like this (untested):

local sKeyPressed

on keyDown pKey
  if sKeyPressed <> true then
    put true into sKeyPressed
    pass keyDown
  end if
end keyDown

on keyUp
  put false into sKeyPressed
end keyUp

When a key is pressed, it checks the flag. If it is not true, then the
keyDown message gets passed so the key will be typed. Then the flag is
set to true. Any more keyDowns will be ignored until the flag is reset
which happens on keyUp.
