How to customise track widgets over menu? [Resolved: Shift+L/R arrow keys]

The new Add Track button displaces the Customize button (at first I thought it was gone entirely).
 
Rather than widening my track area (leaving even less space for the tracks themselves), I'd prefer to go over a menu, but I cannot find where.
 
Sonar 8.5 has its customization function on tabs on the bottom of the window. I use S8.5 on my even smaller notebook for location solo artist recording.

Does that still work?!? Oh, that's so funny! Yes, it does, look at that!
That comes from S8.5, but there it made sense because of the horizontal tab layout.
 
OK, that'll do me. Fantastic, thanks!
 
I'm not sure the Bakers pay much attention to feature requests. I've got work to do.
