Yes, it's part of the touch screen, but that's not a button that can be programmed or deleted. IMO, it should never have been included and I had a customer who repeatedly called to tell me the system didn't work and EVERY GD time, the remote was in Device mode. I created a very usable cheat sheet and included instructions about Device vs Activity mode, but he thought he had everything d!cked and had no idea. His daughter wanted to watch a DVD while I was programming their first remote and as I worked, she sat next to me, looked at the Harmony 1000, pressed one button, waited and pressed Play. I told her absolutely nothing about how to do that, yet there she was, operating the system when she was 3-1/2 years old.
