Understanding the Four-Frame Display
When you begin to drag the segments, the interface changes to the Segment mode four-frame display:
  The Source and Record monitors change to a four-frame monitor display. The two outer frames are updated while you drag the segment forward or backward in the Timeline, indicating the frames you pass as you drag the segment. The two outer frames in the four-frame display make it easy to view and analyze the frames between which you might want to drop the selected segment.
  When you enter Segment mode and you begin to drag the segments, the interface changes to a two-frame display. Only the outer two frames in the four-frame display appear in the Playback monitor.
When you drag the segments, the original highlighted segment remains in place, while a "ghost" segment enclosed in a dotted white box moves along with the pointer until you release it at a new edit point.
When you release the segment into its new position, the actual lift (Overwrite) or extract (Splice-in) occurs. Until then, the segment position is preserved in the Timeline, allowing you to maintain your perspective of the sequence while selecting the new edit point.
