If anyone else is interested the feature is shown here:
Groove 3 Sonar X1 Explained Video-->
Track Control--> Track Pane View Settings--> (between 2:52-3:40 minutes)
It worked fine in the Groove 3 Sonar X1 Explained tutorial.
It is supposed to fit highlighted tracks into the Track View.
If you selected tracks 3, 12, 22 , 40, and pressed Control F, it should fit "only" those selected tracks into the Track Pane.
I could not get "Control F" to work either. (so I just moved on.)
