If you want my program when I am done, email me at mamiller93@gmail.com :) hey, thanks a bunch, I have been creating (TRYING) a program, unfortunately, I am a noob so it takes me a while to make it but your tut was very helpful; about NSSteppers.

I'll be playing more with that if I ever find time to play in Cocoa instead of the devilish C++ that I'm using for all my classes... Awesomeness, thanks for the code suggestions.

I'm sure you can figure out the rest of the down arrow case, and when that's done just return result. For bonus points check to make sure stepper is valid before using it.

Since the codes you're matching on are NS*FunctionKey types, I replaced the mask with NSFunctionKeyMask and that seems to work fine.
