OK, so we were not on the right track...

Well, I finally found the problem. I made a mistake when I wrote that 
code off the top of my head without testing it. The onkeydown handler 
needs to return false (or nothing) if it handled the keypress itself, 
and true if it has to be passed on to the global handler, not the other 
way around. Like so:

onkeydown (
   function(key)
     if key == string.byte(" ") then
       pipmak.saveequirect(360, 180) --width, height
       return false --keypress was handled
     else
       return true --keypress needs to be passed along to the global key 
handler
     end
   end
)

My bad! Seeing that it confused myself, I could maybe change that. 
Since it's not documented  yet, I figure it could be changed without 
breaking too many existing projects. What do you think, is it more 
intuitive to have the keydown handler return whether the keydown needs 
to be passed on (as it is now), or whether it has handled the keypress 
(as I was assuming when I wrote the faulty code)?

By the way, I'm not sure (without testing) where pipmak.saveequirect() 
saves its image file in the current version. It might be next to the 
application, or it might be somewhere inside the application (use "Show 
package contents" in the contextual menu in the Finder to find out).
