Here’s a trick that I use a lot in Ableton Live’s arrange view. Usually I want to extend multiple track loops forward in time. But instead of selecting each one and dragging them out in the timeline, I just position the loop point at the end. Then, important, select the loop point so it is hilighted. After this, if you drag one loop forward, all the other loops within the loop point will also be extended.
Very handy, saves me time.
