I do not know if it's just me that this happens. But when I'm focusing on Console View or even Piano Roll View, if I press Alt + 1 the focus does NOT change to Track View as it should.
If I press Alt + 2 the focus goes to Console view and Alt + 3 goes to PRV, but Alt + 1 does not work.
Does anyone know anything about this?

Hi. What about "D"? Shortcut for opening/closing the multi-dock.
Hope it helps.
All the best.

Not really, but pressing Alt+9 twice (Synth Rack View), it opens and closes this window and after the focus goes to Track View.
Not the best way, but it does.
 
Thanks.

Strange, but glad you figured it out.
