Snapping to the Preceding or Next Clip on a Track
A clip—or an Edit selection including one or more clips on the same track or on multiple tracks—can snap to the end of the preceding clip or to the beginning of the following clip. This is useful for “butt splicing” adjacent clips on a track.
To snap to the preceding clip on a track:
1. Do one of the following:

With the Grabber tool, select a clip.

With the Selector, select an area in a track that contains whole clips. The clips do not need to be adjacent.
2. Do one of the following:

Choose
Edit > Snap To > Previous.

Right-click the clip or Edit selection and choose
Snap to Previous.
The selected clip snaps to the preceding clip on the track so that the two clips are “butt-spliced.”
To snap to the next clip on a track:
1. Do one of the following:

With the Grabber tool, select a clip.

With the Selector, select an area in a track that contains whole clips. The clips do not need to be adjacent.
2. Do one of the following:

Choose
Edit > Snap To > Next.

Right-click the clip or Edit selection and choose
Snap to Next.
The selected clip snaps to the following clip on the track so that the two clips are “butt-spliced.”
