Monterey keyboard shortcuts
I made a keyboard shortcut to send active windows between my (11" Air) laptop's screen and my (non-mirrored) external monitor. I used control+option+command+UParrow for one direction and DOWNarrow for the other direction. They worked OK under Catalina but now often do not work under Monterey. For clarity, those two macros trigger the command in the Window menu to move an active window to the other monitor.
What could be causing this and is there a solution? I'd have thought that if there was a key-combo conflict the Mac would have notified me. Please help. Thx!
