Introduce new keyboard shortcuts:
1 to 9 focuses the video tracks 1 to 9 Alt + 1 to 9 focuses the audio tracks 1 to 9 Q then 1 to 9 selects the target stream (1 to 9) for currently focused track
Alt+1 and Alt+2 is giving an error on my system (ambiguous shortcut), Alt+3,4,5,etc works as intended. I'm on Neon as I think you are too, what could be the conflict?
Also notice Alt+3 on a 2 tracks project lands on track 2.
On Windows Alt+1 and Alt+2 works fine and selects the correct audio track.
Solved! Awesome! :)
