Figure 29.1 shows the Sequence box realign itself against the time ruler after the new Start time of 2.05 seconds has been entered.
Some Sequence boxes have also been deleted since the previous diagram (Fig 28.1) by selecting them individually with the mouse and then choosing Edit >> Cut; you can also use a keyboard shortcut for this; for example, Ctrl-X on Windows. To delete all Sequence boxes in a time period for a particular track choose Edit >> Sequences >> Delete.
