A sequence may contain several video and audio tracks.
When you add a clip to a sequence, you need to specify which track
or tracks it should occupy. You can target one or more tracks, of
both the audio and video varieties. The way you specify target tracks
depends on the editing method you use.
When you drag a clip to add it to a sequence, you target
the track by dropping the clip into the track. If you are inserting
the clip, pressing Ctrl (Windows) or Command (Mac OS) as you drag,
triangles show which tracks will have content shifted.
Targeting a track while dragging a clip to a sequence
When you add clips to a sequence using the Source Monitor
controls (or keyboard shortcuts), you must specify target tracks
in advance. You can target more than one video track or more than
one audio track at a time. Also, you can choose to target a video
track only or an audio track only. Click the track(s) you want to
target in the track header area of a Timeline panel. The track header
area for a targeted track appears highlighted.
You
can also assign keyboard shortcuts to some track targeting commands.

You can map the tracks of a clip in the Source Monitor to
one or more tracks of a sequence by dragging the source track indicator
representing each of the source clip’s tracks into one or more selected
tracks of the sequence. Audio source track indicators can be placed
only in audio tracks matching the source clip’s channel configuration.
For example, the audio track indicator for a stereo clip can be
placed only in a stereo track in a sequence.

If you overlay a clip, only the clips in targeted tracks are
affected, whether you drag the clip or use a Source Monitor’s Overlay
button.
If you insert a clip, the clip goes into the targeted tracks,
and clips in any unlocked tracks where the source clip lands shift
to accommodate the insertion. You can specify other tracks to also
shift by enabling Sync Lock on them.
To insert a clip and not shift clips in other
tracks, Ctrl-Alt-drag (Windows) or Command-Option-drag (Mac OS)
the clip into the track.
You can drag video clips to any video track; however, you can
drag audio clips only to a compatible audio track. Audio clips can’t
be added to the master audio track or submix tracks, and they can
be placed only on audio tracks of the matching channel type: mono,
stereo, or 5.1 (see About audio tracks in a sequence).
Clips with linked video and audio can be dragged to either a
video or an audio track, but the clip’s video and audio components
appear separately, in the appropriate corresponding tracks.
Note: You can drag a clip to any unlocked, compatible track in a
sequence, no matter which tracks are currently targeted. You can’t
target a locked track. Locking a target track deselects it as the
target.
