In addition to allowing you to execute your cues from the Transport Window, you can also pause them and even seek forward and backwards.  The status bar can be dragged backwards and forwards to select the proper point in the cue to seek.  Cues that are connected together by Waits and Autofollows will appear as one entry in the Transport window.  Because of this, if you have an involved cue sequence containing many separate cues all separated by Waits and Autofollows and the director wants to start two minutes in, you can simply drag the status bar two minutes forward and all the cues will synchronize to their proper place, even Volume Changes!
