This quick walkthrough from Ableton's Learn Live series shows how the Clip Overview helps you navigate a full arrangement without getting lost in the timeline. It sits above your tracks and gives a compressed, birds-eye view of every clip you've placed, which makes jumping around a busy project much faster than scrolling track by track.
Drag the pane downward to resize it for a bigger view when you need more detail. Click and drag horizontally to scroll through the arrangement, or drag vertically to zoom in and out, letting you move fluidly between a wide-angle view of the whole song and a close-up on a specific section.
