I personally use:

bind-key -n M-1 select-window -t 1

bind-key -n M-2 select-window -t 2

bind-key -n M-3 select-window -t 3

(...) For an IMHO even more convinient ALT+Number to switch directly to the tab in question, just like in firefox.

That's very similar to CTRL+B then Q then Number. But I have about 5+ panes so I found using the arrow keys a lot easier
