I agree with Sascha that keeping unassigned focus tracking mode for now is better.

Actually, if we should toggle something regarding tracking, I'd better implement a global toggle tracking and / or individual toggle for mouse tracking, focus tracking and navigator object tracking. That's not part of Windows Magnifier scripts, but I have implemented similar gestures (toggle globally tracking, toggle focus tracking, toggle mouse tracking and toggle caret tracking) in Windows Magnifier NVDA add-on improvements. And being able to toggle tracking globally or partially on the fly (i.e. without needing to open Windows Magnifier settings) proves to be very useful.
But that may be another PR.

For now, I'd recommend only the filter cycling gesture (NVDA+shift+I).
