The skip-to-hash button becomes a 30 second skip button.

1. Bring up any recorded program. (I believe you have to
be watching a recorded program rather than "Live TV"
in order to enable the feature.)
2. On your TiVo remote, key in the following sequence:
SELECT PLAY SELECT 3 0 SELECT
3. If you've successfully entered the code, you should
hear three "bings" in succession to let you know that
you've successfully enabled the 30 second skip
feature.
4. The skip-to-hash button on your remote will now skip
forward 30 seconds during playback.
5. To undo this just re-enter it.
