Arranging : Time, Tempo, Meter, Key, and Chords : Cut Time : Cut Time Options

Cut Time Options
Options for the Cut Time command include:
Start, End, and Length
Sets the start and end points for the selection, and the selection length.
Realign
The Realign controls let you choose which items shift when time is cut, as follows:
*   
If your Main Time Scale is set to Bars|Beats, you can choose to realign meter events only, or choose to realign a combination of Meter and Tempo rulers together, all tick-based markers and tracks, and your choice of sample-based tracks.
*   
If your Main Time Scale is set to an absolute timebase (such as Min:Secs), you can choose to independently realign conductor events, tick-based markers and tracks, and your choice of sample-based tracks.
Meter Ruler Only
If your Main Time Scale is Bars|Beats, you have the option to remove time from the Meter ruler only. Meter events within the selection are removed, and meter events that occur after the end point of the selection are shifted to the selection start point.
If your Main Time Scale is sample-based, Realign Meter Ruler Only is not available.
Meter, Tempo, Key, and Chord Rulers, Tick-Based Markers and Tracks, and Sample-Based Markers and Tracks
Cuts time and realigns the Meter, Tempo, Key, and Chord rulers, and all tick-based markers and tracks.
If the time selection includes any tick-based clips, the selected area of the clips is deleted, and clips following the selection are shifted forward.
Using the pop-up menu, you can also choose to cut time from All or No sample-based markers and tracks. If All is selected and the selection includes any audio clips on sample-based tracks, the selected area of the clips is deleted, and clips following the selection are shifted forward.
