Grouped before
OK I did a test with 3 grouped tracks and 6 playlists
If you put the cursor in Lane 1 of the top track and hit "CTL + ;" the cursor moves correctly but the screen view jumps (putting the next track down in the center -*repetitive CTL + ; works smoothly but if you go CTL + P it jumps again putting the upper track at the top f the screen.
With 7 lanes zoomed to take up the height of the window it is jarring- to me.
