Cut, copy, and paste regions in the Tracks area
You can cut or copy regions in the Tracks area, and paste them at a different position. You can also paste a copied region at the same time position, to quickly double the region for use on another track.
Cut a region
Select the region, then choose Edit > Cut (or press Command-X).
Copy a region
Do one of the following:
Select the region in the Tracks area, then choose Edit > Copy (or press Command-C).
Option-drag the region.
When you copy an audio region, the new region retains the name of the original, with a sequential number added. For example, for a region named MyLoop, the first copy is MyLoop.1, the second copy is MyLoop.2, and so on.
Paste the region
Move the playhead to the point in the Tracks area where you want the region to start, then choose Edit > Paste (or press Command-V).
