Take away the begin...end org block itself which I only put to protect the org code for the email. You should then be able to edit the src block with no problem. #+begin_myclass #+begin_src octave y = 3 * x + 5 #+end_src #+end_myclass If I have point within the octave src block, C-c ' works fine for me. -- : Eric S Fraga via Emacs 28.0.50, Org release_9.4-118-g2a4578.dirty
