We can assign a keyboard shortcut for the Comparison view, although only to activate it, not to change one to the other options.
I would like to have keyboard shortcuts for each comparison mode.

I’ve assigned a shortcut for toggling Comparison View on and off. Unfortunately, this shortcut only works when the Program Monitor is the active panel. Why is that a good thing?

Please change this, so that toggling Comparison view on/off - and switching between its modes - works no matter what panel is active (ECP, EGP, Lumetri Color, Timeline are the most important).
