The timeline shows every lane of your edit: captions, graphics, effects, filter, video and audio. You can edit it by hand at any time.

## Editing by hand

- **Select** a clip by clicking it. Shift-click selects a range; Cmd/Ctrl-click adds or removes a clip.
- **Trim** by dragging a clip's edge. Hold **Shift** to ripple-trim and close the gap.
- **Move** clips, graphics, captions, music and effects by dragging them.
- **Cut** with **Cut at playhead** above the timeline.
- **Right-click** a clip for rotate, flip, speed (25% to 400%), reverse, detach audio, delete and ripple delete.
- **Zoom** with the slider above the timeline.
- **Lane controls**: the eye hides a lane, the speaker sets a lane's volume, the pencil renames it.
