greetings stefan.. i just pulled down a recent release of emacs ( https://emacsformacosx.com/emacs-builds/Emacs-29.1-1-universal.dmg), started with `~/Downloads/Emacs.app/Contents/MacOS/Emacs -q`, and the issue is still there. are you using magnet? the default bindings of ctrl-opt-leftarrow or ctrl-opt-rightarrow (using mac keyboard nomenclature) to move the window to the left or right of the screen don't work. if i type ctrl-opt-x, the minibuffer reports "C-M-x is undefined", but doesn't say anything when i type ctrl-opt-leftarrow or ctrl-opt-rightarrow. again, this does work with the railwaycat build (and the 15 other mac apps i have open). i just verified i don't have any global shortcuts defined by going into system settings/keyboard shortcuts and defining ctrl-opt-leftarrow to show notification center. it doesn't show a conflict with any other shortcuts, and it overrides the magnet binding and shows notification center.
