I'm trying to quit the habit of using s-v, s-c and similar keyboard shortcuts for copy paste in Emacs on mac os/osx. I'd like to turn them off but can't find any information on how to do this.
There's a chance this was turned on at some point and it does not come as a standard as the .elisp file is unwieldy and old. It doesn't seem like there's something doing this in it though.
Of course manually remapping all the keys would be possible if there's no easy way to do this.
When building the vanilla version of Emacs --with-ns, the default key bindings in ns-win.el are put into place. To disable specific bindings, just set them to nil. If a binding is set outside of Emacs (e.g., System Preferences of OSX), then Emacs would never even get the opportunity to see the keys because they would get intercepted before reaching Emacs.
(define-key global-map [?\s-c] nil)
(define-key global-map [?\s-v] nil)
For a self-contained version of Emacs, e.g., downloaded from https://emacsformacosx.com/ or manually built from source using --with-ns, the ns-win.el library is located in the package archive:
/Applications/Emacs.app/Contents/Resources/lisp/term/ns-win.el
If anyone is interested in seeing the default key bindings, please feel free to inspect the source code of ns-win.el.
I swap my option and command keys, so that i can use the key to the left of the space bar as Meta by doing:
In the Terminal application:
BEWARE that the swap takes effect for every application on the Mac, so you'll need to re-train your brain (well, at least your thumb) to use option instead of Command for your Mac key equivalents.
But it is possible to retrain, and then the key to the left of space will always work as Meta in the Terminal application. Plus you will be entertained when people who try to type use Command-Whatever on your computer discover it doesn't work and become confused.
