Multi view is useful for viewing your sequence in a Storyboard format while developing continuity between shots. With Multi view, you see the entire image, and you can cycle through viewing 2, 4, 9, or 16 shots.
To view multiple shots simultaneously in the Player:
The first two shots displayed are the current frames on Playheads A and B. The rest of the shots displayed are the selected shots, displayed sequentially from left to right in the order of selection.
You can make a new selection of shots while you are in Multi view. After you have selected the new shots, press F6 to update the Multi view display with the new shots.
