#+BEGIN_SRC emacs-lisp :results none
    ;; allow comment region in the code edit buffer (according to language)
    (defun my-org-comment-dwim (&optional arg)
      (interactive "P")
      (or (org-babel-do-key-sequence-in-edit-buffer (kbd "M-;"))
          (comment-dwim arg)))

    ;; make `C-c C-v C-x M-;' more convenient
    (define-key org-mode-map
      (kbd "M-;") 'my-org-comment-dwim)
#+END_SRC
