I have a Logitech y-sab59 keyboard and it comes with shortcut keys like play/pause volume up/down, mute, etc., but it doesn't have fast forward or rewind keys. I'm pretty sure its possible to change the preset values with the keyboard drivers but I lost the CD, and I looked everywhere for the drivers, including the Logitech site, and I can't find them. I know its possible to add values to the Function keys (F1,F2, etc.) but I don't know how. Any help on programming the function keys to fast forward/rewind buttons would be appreciated.
