In org-mode, I use preview images for various things such as latex formula and linked images (e.g. [[file:xxx.png]]]). At times, I need to change the code for these and switch back to the code view. I know I can use things like C-c C-x C-l for LaTeX and M-x org-toggle-link-display.

Is there a simpler way to switch back to the source, e.g. by double clicking the image or using one key-binding/command on it, for all types of preview images?

  • There was one (at least for LaTeX fragments): the very busy C-c C-c would restore the code view (I don't remember if it toggled, but I think not). However, that was deleted some time ago in order to make the key less busy. I don't think there is anything like what you are looking for now, but it should not be too hard to add a function that figures out what org-element is at the location of the event and does the necessary to flip the state if it finds the element to be either a LaTeX fragment or a link (and does nothing otherwise). – NickD Jun 19 at 13:18

Along the lines of my comment, here is a function that toggles the state of a link or a LaTeX fragment at point. It's bound to C-c t (for "toggle") only because that was undefined in my Org mode keymap:

(defun ndk/toggle-state-at-point ()
  (let ((ctx (org-element-context)))
    (pcase (org-element-type ctx)
      ('link           (org-toggle-link-display))
      ('latex-fragment (org-latex-preview)))))

(define-key org-mode-map (kbd "C-c t") #'ndk/toggle-state-at-point)

It does nothing if the context at point is not a link or a LaTeX fragment.

N.B. org-latex-preview was introduced in Org mode 9.3 and is replacing org-toggle-latex-fragment which is deprecated. For Org mode versions < 9.3, replace the org-latex-preview above with org-toggle-latex-fragment. Thanks to @tinlyx for pointing out the problem.

  • Thanks. It seems org-toggle-latex should be org-toggle-latex-fragment in my Emacs 26. – tinlyx Jun 20 at 4:03
