Editing : Editing Clips and Selections : Creating New Clips : Separation Grabber Tool

Separation Grabber Tool
You can use the Separation Grabber tool to automatically separate an Edit selection and move it to another location or another track.
To separate a selection with the Separation Grabber tool:
1 With the Selector tool, make an Edit selection. The selection can reside within a single clip, across adjacent clips within the same track, or across multiple tracks.
2 From the Grabber tools pop-up menu, choose the Separation Grabber tool.
 
3 Drag the selection to the new location, or to another track.
 
A new clip (or clips) containing the previous selection is created, separate from the original selection. New clips are also created from the material outside the original selection.
To separate a selection without affecting the original clips:
1 With the Selector tool, make an Edit selection. The selection can reside within a single clip, across adjacent clips within the same track, or across multiple tracks.
2 From the Grabber tools pop-up menu, choose the Separation Grabber tool.
3 While pressing Alt (Windows) or Option (Mac), drag the selection to the new location, or to another track.
 
New clips containing the previous selection are created and placed at the new location. The original selection and clips remain intact.
