Sigh, really glad to hear that!

The problem with the keyDown messages is that I need the rest of the script 
inside the repeat loop to be executed constantly (to present a stream of 
objects on the screen). Like this:

repeat
     presentSomeObjects -- this has to be performed constantly
                                    -- sometimes there is a key pressed; in 
this case I need:
   "keyX"-->handler1
   "keyY"-->handler2
   "keyZ"-->handler3
end repeat

I have the strong feeling, that I´m missing something here. Of course "on 
keyDown" won´t work, but how else can I achieve this behavior?

Thank you,
