a couple hurdles I had with Rev

[Jared Smith]

Thanks for the quick reply. I guess I did something wrong when I
search for "deleteKey."

By the way, why doesn't the Undo command under "Edit" in Rev work? I
accidently deleted most of my program and tried to undo it, but it
didn't work. So I decided to close the program without saving.
Annoyingly, it saved anyway and so I have to write everything over
again. I'm kind of frustrated right now.
