Use Case I was running into the need to toggle track output today, where I'm nudging an edit point as I'm looping. One problem: I want to turn off the "camera clutter" clip on V2 momentarily as I adjust the edit point, then turn it back on (as I'm still looping).
It works great with the mouse, and I'd much rather toggle it back on with a shortcut similar to my other timeline toggles.
I find it a little odd that it is missing from Timeline shortcuts.
Shortcuts exist for all the other timeline toggles.
