Channels DVR with Apple TV Remote

How do I use Channels DVR with the remote that comes with Apple TV? In particular, how do I skip commercials?

When the “Skip commercial” button appears in the lower right corner, click the touchpad to select. If you’re asking about skipping forward or back, I believe you do so by double clicking the right or left side of the touch pad. Not 100% sure on that.

Thank you!
