Hi
The suggested steps work fine here using VP 8.45
".....Not if you are in Sequence Preview, which is the default opening of VP. Only by pushing one button or the other until the UNLINK command became available did this work....."
Unlinking the audio from a clip is done by right clicking a timeline track. It doesn't matter which display you have up. (For most editing I set dual display from Options. ) I have noticed that this occasionally just invokes the data popup for the track. Clicking a second time or in a different area usually brings up the correct menu
"......Nope. If you swipe it, it does nothing. If you merely click on it it turns blue. Yes, this moves the red longtailed cursor ten seconds into the clip....."
Sorry if that was misleading.. You are correct. It's just a click but if you are changing just the seconds value by swiping the displayed value area, it will highlight.. But as you say it sets the timeline cursor to the desired position
".........Which makes the entire audio track disappear. ......"
This should not happen. In fact, even if you have not unlinked the audio, using the split scissor icon under the sequence preview window and selecting audio track 1 will automatically unlink and split the audio track.
