Passing through certain M-<key> command to OS in Emacs
Is there a way to pass a certain M-key combination to the OS? I'm using OSX and I'd like to have the "Move focus to next window in application" key which I use to work also in Emacs, currently it just says that M- is undefined (the key combo works in other apps, I use CMD as meta).
I found a way to switch between the frames with the same command as I have configured OSX to use (CMD-§).
I just added this to init.el:
(global-set-key (kbd "M-§") 'other-frame)
So I don't need to "pass this" to OS, because this will have the exact same effect.
