This quick Ableton Live tip shows how to duplicate or delete a whole section of your arrangement in one move, instead of dragging clips around track by track. Drop an Insert Marker to select a range across the timeline, whether it spans one track or your entire session.
Once the range is selected, head to the Edit menu and choose Duplicate Time to copy that section forward, or Delete Time to remove it and pull everything after it back together. Handy for repeating a chorus section, extending an intro, or cutting a section out of your arrangement without leaving gaps or manually shifting every track.
