The only thing I didn't like about it was that it couldn't be bound to another key. I used to bind it to the spacebar in Diablo2 because I used to press the 'Windows' key all the time. Another reason for it is that while your fingers are above the F1-F4 keys, you have to dislocate your thumb in order to put it on the ALT key <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
My thumb would be thankful if this feature could be implemented in <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" />
