Opening ShotCut in full screen using Windows 10

Since the fullscreen menu option and the shortcut (F11) don’t do anything useful on windows, would it make sense to be remapped to External Monitor on current screen*? (basically a one key shortcut to the big video player without any distractions).

I find the external monitor feature really useful but it’s too cumbersome to use it as it’s not very quick to activate (navigate to the option in the menu + submenu). Also I need to first move shotcut to the other monitor so I can select the main monitor from the list (*which I don’t understand why it is disabled in the first place, it artificially limits one monitor users completely (you can alt+tab to bring the main window back anyway)).
