Video Edit Magic supports both - multi-select as well as extended select. Hold down the Ctrl key and individually select multiple sources or hold down the Shift key and select a range of sources by clicking the First and Last source in sequence. When the sources are all highlighted, you can move them together in synchronization. Drag them using the mouse while holding down the Ctrl key or use the arrow keys on the keyboard for precise movements.

How do I keep the audio part in sync with the video part? Whenever I move the video part, the audio part does not move.
