Well, I was afraid of that. Glad you sent over that code. I was thinking about testing the range of nKeyCode and wasn't thinking about ISALPHA (a command I don't find much use for), but it's a more sublime solution.

I wonder why the format code does not work? Is this considered a bug or by design or do you know?

Thanks to each of you.
