If you are needing to cut and split tracks for perspective, a quick method is as follow:
Group the tracks that you are wanting to split. (If you have many edits - it may be worth creating a region group first). Go through and place a cut to your region on the edit points. Then, using the "Grabber- object" tool, go through and "shift click" your regions which need to move down to a new set of split tracks (this could be every second region). Then drag these tracks down to the tracks used for the split. This is much faster then going through and dragging each region edit selection at a time!
