That's not what happened.  I was looking at three *other* dimensions
 in the right window, and the left window reset to *them*.

I'd suggest what we have in the prototype: "go home" separate from
 "reset view".  If you want them the same it can be a keybinding that
 puts both functions on one key.

No.  I expected caps for the left and lower-case for the right.
 Since going backwards through the list is a lot less important than 
 rotating the left window view, the simpler keystroke should rotate.

Best, Ted
