Hi,
  I have a question about Mac keycodes. Is there a difference(in
keycode) between the shift key on the left side of the keyboard and
the one on the right? I know on windows computer there is. All of my
searchings have led me to belive that both shift keys produce the same
keycode. What about the command keys, etc?

Thanks,
