MacOS (emacsformacosx) c-spc, does not run set-mark-command

[Uwe Brauer]

Hi

Does anybody know how to achieve the traditional binding of 
C-space to set-mark-command on MacOS (for emacsformacos)?

Shift arrow down works, but will not work for a lot of features in org
mode.

Thanks

Have you verified c-space is not being used by the macOS UI as a
shortcut for something like spotlight search?

I now use spacemacs, but when I used my own setup, I don't recall having
to do anything special to get this behaviour apart from disabling macOS
shortcuts.

I have seen differences in this behavior depending on the Emacs build. The
emacs-mac port (https://github.com/railwaycat/homebrew-emacsmacport) seems
to intercept certain Mac-specific keybindings such as C-space and C-M-space
and gives them their "Mac meaning", e.g. to bring up Spotlight or the
symbol chooser. I could never figure out how to disable this behavior.

Now I use emacs-plus (https://github.com/d12frosted/homebrew-emacs-plus)
and this no longer happens.

Normally, you need to disable those 'shortcuts' at the OS level i.e.
under the keyboard shortucts item in macOS preferences panel. Problem is
any macOS shortcut will grab the keys before Emacs sees them. Not sure
how the emacs-plus version gets around this.

Right, it seems and issue of the OS shortcuts as C-space is for
switching keyboards (US->spanish>etc etc).[1]

Do you know how to change or disable them?

I use the alternate arrangement i.e. ‘C-@’. This requires pressing three
keys - Control, Shift and [2/@] on my keyboard.

C-space is used by the OS for some other things. You should be able to
disable that in preferences and use it in Emacs.

On macOS, these shortcuts can be changed in the Keyboard preference panel.

I'm not on a mac at present, but from memory it is under system preferences ->
keyborad -> shortcuts.

I think the mapping is intercepted by MacOS to start the Spotlight
search.  Open Preferences, got to Keyboard -> Shortcuts -> Spotlight and
disable the keyboard shortcut.

I don't understand your question.  C-SPC should work out of the box I 
think, at least it does here.  The M-SPC (just-one-space) does not with 
default settings, because M-SPC is used for Spotlight search, but you can 
deactive this easily in the preferences if you want.
