Org mode: How to fold all other headings except the current one

Published on Sep 9, 2021, by Junji Zhi

If you are in a long org file, sometimes it’s helpful to fold all other headings and focus on the current one.

There are two ways to achieve this:

If you don’t care about other headings, se markdown-narrow-to-subtree. It hides all other headings. The shortcut is C-x n s. To undo it, you use C-x n w
If you still want to see other headings while you are edit the current one, I found a StackOverflow answer and adapted for my need:

(defun org-show-current-heading-tidily ()
  (interactive)  ;Inteactive
  "Show next entry, keeping other entries closed."
  (if (save-excursion (end-of-line) (outline-invisible-p))
      (progn (org-show-entry) (show-children))
    (outline-back-to-heading)
    (unless (and (bolp) (org-on-heading-p))
      (org-up-heading-safe)
      (hide-subtree)
      (error "Boundary reached"))
    (org-overview)
    (org-reveal t)
    (org-show-entry)
    (show-children)))
