I do not know by which settings, but I do see that Org snippets with programming language inside behave just as the mode: If I have this in Org: #+begin_src emacs-lisp :results output silent Then I can see syntax highlighting and I get indentation as well. But not all features. Maybe soolution could be to narrow-to-region, change the mode, and then by exiting from narrow to region to change it back to original mode. It could be one function.
