Hello, Due to a friend's request, I've tried to offer AUCTeX key bindings within Org documents via a minor mode, called "org-auctex-keys".
If you're interested, check it out at https://github.com/fniessen/org-auctex-key-bindings. Note that I'm willing to add extra AUCTeX keys -- but I don't use AUCTeX enough to know what's important to transfer to Org. Best regards, Fabrice -- Fabrice Niessen Leuven, Belgium
