CS5 won't let me change a shortcut?

[LadyJemima]

I want to change the Curves shortcut. I go to the Keyboard Shortcut menu and sure enough, there it is. I click it and am able to delete the shortcut.

#1) How is one supposed to enter the "command" (mac) key? If I simply hit it, nothing happens.

#2) If I try to enter another key (say, "z") it gives me an error that says "Z is an invalid shortcut. Menu commands must include ⌘ or an F-key in their shortcuts".

I'm sure this is incredibly simple. I just don't seem to get it! :neutral:

I'm guessing you need to press and hold the command or option or shift key or some combination and another key.

Oh my gosh, DUH, I just figured it out. Photoshop puts in the command of whatever keys you press.
