Presently I can jump back and forth from Track view to Console view with D.
 
It would be nice if with a similar key stroke I could jump from one state of the Console view (showing all tracks I presently have) to another state showing just the busses in the Console view.
 
The bus curtain in Console view obviously works, but it would be spiffy if I could just hide/show all the busses with one key stroke.

I can think of two ways to do this now:
Screensets
Or
Bind the "Strips|Tracks" and "Strip|Buses" functions in the Console View area to keyboard shortcuts (these are also in the Console view Strips menu).

Screensets can be quirky, so I was avoiding that as a concept - although I know it's possible that way.
 
Hadn't thought of your idea of binding those.  I'll have try that out.  Still would be nice to have as an out of the box prefab keystroke, since these are very commonly used sections.
