You
            can scrub audio at any speed between -100% and +100% of real time
            (locked rate scrub) or do a free form scrub. You can scrub a single
            audio track or all audio tracks.
         
         To scrub audio in the timeline:
         
         
            - Enable
               the Scrub Audio button.
            
- Do one of the following:
               
                  - To scrub all audio tracks, place the
                     focus point on the video track.
                  
- To scrub a single track, place the focus
                     point of the positioner on that track. See 
                              Changing the Current Track.
                  
 
- Click in the scrub bar at the location
               in the timeline where you want to scrub the audio. Continue to hold
               down the mouse button.
            
- Do
               one of the following:
               
                  - For a locked rate scrub, press Ctrl+Shift and drag the positioner
                     left or right to scrub the audio. Dragging farther to the left or
                     right increases the playback speed. You cannot scrub faster than
                     real time.
                  
- For a free form scrub, press Ctrl and drag the positioner left
                     or right to scrub the audio.
                  
 Dragging farther to the
                  left or right increases the playback speed.
                You can toggle between
                  locked and unlocked scrub modes on the fly, by alternating between
                  the Ctrl and Ctrl+Shift hotkeys.
                TipYou can quickly scrub
                     a single track without moving the focus point by dragging the positioner
                     with the cursor positioned over that track.
                   
- To
               scrub one frame at a time, press Ctrl+Shift and
               click the Back One Frame button in the player controls to go back
               one frame, and Ctrl+Shift and
               click the Forward One Frame button in the player controls to go
               forward one frame.
