Use
            cue marks to mark frames of interest on a clip. You can then quickly
            go to the marked frames. Cue marks are for reference purposes only;
            they do not affect the clip and are not used in any editing operations.
         
         You can add a mark to
            all tracks (cue mark) or to a single track
            or layer (segment mark) on the timeline.
            Segment marks move on the timeline as you trim, slip, or slide a
            clip whereas cue marks stay at the same position on the timeline.
         
         You can also add cue marks and cue mark comments
            using the cueing controls in the Player, shown in the following
            example.
         
         To insert marks:
         
         
            - Go to the frame where you want to insert
               the cue mark.
            
- Add a mark by doing one of the following:
               
                  - Enable Cue Mark in the Player to insert a cue mark on the clip.
                  
- Press Shift+Alt (right side of keyboard to insert a cue mark on the entire
                     timeline.
                  
- Press Shift+Ctrl (right side of keyboard to insert a segment mark
                     on the current track or layer.
                  
 Cue marks set on the
                  entire timeline appear on the timebar and on the timeline. Segment
                  marks set on a track or layer appear only on the timeline.
                NoteYou can add marks
                     while the clip is playing.

                  - Press Alt+S to move to the next cue mark
                     on the clip.

                     mark on the clip.

                     segment mark on the current track or layer.
