Using Auto Select to Specify Tracks for Selections

Auto Select controls determine which tracks are affected by an operation. When sequence In and Out points are defined, operations such as the Copy and Lift commands are limited to the regions of tracks with Auto Select turned on between the Timeline In and Out points. You can intentionally turn off Auto Select controls for tracks that you don’t want to operate on.

As you can see in the picture below, tracks A1 and A2 are not highlighted because Auto Select is not turned on for those tracks.

The Auto Select controls provide precise control over which part of the Timeline you cut, copy, or delete from. For example, if you have a sequence with one video and two audio tracks, by turning off Auto Select on audio tracks A1 and A2, you can select items on track V1 by setting In and Out points in the Canvas or Timeline. Items in the audio tracks are not selected.

If you press the Delete key, only the items on track V1 are deleted.

To turn on Auto Select on one track while simultaneously turning off Auto Select on all other tracks
  • Option-click the Auto Select control on the track you want single out for Auto Select. (If Auto Select is off for all tracks, you need to Option-click the control twice.)

    If you Option-click the Auto Select control on a video track, Auto Select is turned off on all other video tracks in the sequence. If you Option-click the Auto Select control on an audio track, Auto Select is turned off on all other audio tracks in the sequence. Option-clicking allows you to quickly target a single track for editing operations.

To explicitly select a region between Timeline In and Out points
  1. Turn on the Auto Select controls for tracks you want to select from, and turn off the Auto Select controls for tracks you want to exclude from your selection.

  2. Set In and Out points in the Timeline.

  3. Choose Mark > In to Out (or press Option-A).

The region of clips between the In and Out points on tracks with Auto Select turned on is selected.

In some instances, the Auto Select controls are ignored:
