for this particular shortcut, “Hide Disabled Tracks”, in the list for the visibility agents, I’m not able to assign a shortcut, because I can’t find it in the key command list.
Is this present under my nose or is it missing?
You’re welcome!
But there should be an option to simply add a key in the Shortcuts editor,
(which can be done with the other visibility options), instead of all that faffing around with logical editors and macros.
