Moving and Duplicating Selection Ranges
To move a selection range, click and drag it to a new position.
This will move the contents of the selection range to the new position. If the range intersected events or parts, these are split before moving, so that only the sections within the selection range are affected.
To duplicate a selection range, hold down Alt and drag.
You can also use the duplicate, repeat, and fill loop functions that are available for duplicating events.
