You can use keyDown as long as you get rid of the repeat loop, and you can do that using send...in. Basically your code will look something like:

on presentSomeObjects
 -- do something here
 send presentSomeObjects to me in 1 second -- or whatever time
 put the result into gPresentMessage -- allows you to cancel if needed
end presentSomeObjects

on keyDown pWhichKey
 -- do something based on the key
end keyDown
