To trim a sequence audio clip item in the Viewer:
1 Disable linked selection by doing one of the following:
 If linked selection is on, click the Linked Selection button (or press Shift-L) to turn it off.
 Hold down the Option key and click the audio item.
2 Drag the audio item from the sequence to the Viewer.
The audio item opens in the Viewer by itself.
You can also double-click the audio clip item to open it in the Viewer, but you may
need to hold down the Option key to make sure that only the audio clip item is
selected when you double-click.
The link between the audio and video in your clip has not been broken, but you can
now trim the audio independently of the video to which it’s linked.
