What I was trying to tell you is that there is a MX-500 Q&A thread set up for everyone to ask their questions, not that the answer was there already. But anyway, each page of the LCD screen has editable text labels for the buttons adjacent to them. The LCD is not a touchscreen. Whatever function you assign to a button, the LCD label can be you revised to say "Pause" or whatever fits. I believe there currently is no plans for the remote to be PC configurable.
