Using Multi-Track Gestures to Control Playback
If your portable computer has a Multi-Touch trackpad, you can use the rotate gesture to
play back audio in the Timeline. The speed of playback is determined by the speed of
the rotate gesture. For example, a very slow clockwise rotate gesture scrubs the audio
forward from the position of the playhead. For more information on scrubbing audio,
see
Scrubbing Audio Files .

µ
Use the rotate gesture clockwise.
To move the playhead to the left
µ

You set the height of tracks, busses, and submixes in the Timeline using the Track Height
control. The Track Height control has four settings. The smallest rectangle sets the track
height to a minimized setting, with each track (and track header) reduced to half-height,
allowing more tracks to be displayed in the Timeline.
