Try Toggling the track's output.
Thanks Jim - Can you give a little more info about toggling the tracks output? I would just want to disable the cut between the edit, not the entire track. There may not be a way around doing addition mouse clicking.
If that's possible, you will find it in the shortcuts menu. I've never looked for it myself.
Nope, no keyboard shortcut to disable a single clip, on a specific video track, under the playhead location.
For your situation, I would be inclined to just highlight the unneeded layer(s) and hit the Delete key. I could do that relatively quickly and it would offer a quick and clear visual representation of changes from the Program track.
