Ripple trims the previous or next edit point to the Playhead. You do not need to select an edit point to perform a ripple trim to playhead edit. Like the Extract command, a ripple trim to playhead edit does not affect clips on other tracks that are locked or not sync-locked, but all other tracks will have the region ripple-deleted. Sequence In and Out points are not affected.
Note: A ripple trim to the playhead at the beginning or ending of a clip is sometimes called "Top and Tail" in editing terminology.
