Go to Marker Number 13 ⌃3
Position the playhead at the beginning of the thirteenth marker. I tend to name my markers, so trying to use them by number isn’t very easy. I suspect that I would find it easier if I had a Marker list open and visible. If the markers aren’t named Marker 1, Marker 2…Marker 20 then the list doesn’t help either. It would help if there was a sequence number in the list of markers.
