I'm halfway though editing a project in Final Cut Express. After accidentally hitting a combination of keyboard keys, when I now drag and drop a clip from the viewer into my timeline the audio and video aren't connected. So I can only move one (audio or video) across at a time. Once they're in the timeline, the audio and video aren't linked. All the other clips in the timeline that were there before are still linked, and Linked Selection is on.
Any help as to how to reconnect them, so the clips are initially linked when I drag them from the viewer would be much appreciated.
