I have been using my Pronto for a few weeks now and I love it. I have the 2 bottom buttons set to pause (left button) and play (right button) my VCR. After using it for a while I think it could be more useful if I could have some sort of double click feature on these buttons. Something like left button pause but hit it twice in quick succesion (double click) and that would stop the tape. The right button could play the tape but double click it and the tape would fast forward. Is such a thing possible?

No, it's not possible with the Pronto. A button can only have one function. This has been requested in the past, in addition to similar features such as a rotating code (each time you press the button it changes the next function -- play/stop/play/stop).
