Yeah it's the skip button (just below Mute), and the button to jump back is a curved arrow button just underneath the skip button. It's totally counter-intuitive visually, but the feature is there and I use it all the time too. The only thing is that the jump forward is longre than the jump back, so if you jump too far forward, sometimes one jump back will get you closer to the end of the commercial break, but sometimes it will still be in the show.
