tengizk - are you talking about a "go back" like a rewind or a go back to a certain screen type jump?

After re-reading this, I get the idea you're looking for a rewind type go back.

All of my viewing activities use the 5 hard buttons at the bottom for these functions. I keep it consistent for my Tivo, VZ DVR, DVD & Media Center PC.

By keeping the 5 hard keys consistent, it has been quite easy for myself, my wife and kids to use the remote without having to look at it. Almost all of our TV viewing is from recorded content, so using the firm keys to skip commercials or jump back is used very frequently.

It's layed out like below:
[PAUSE] [BACK] [PLAY] [FORWARD] [SKIP]
