Emacs lisp function to jump to random org heading. Useful for getting a random note from a giant org file.

random-org.el

(defun my/org-random-heading ()
  "Jump to a random org heading in the current org file."
  (interactive)
  (goto-char (point-min))
  (let ((headings '()))
    (while (re-search-forward "^\\*+ " nil t)
      (push (point) headings))
    (when headings
      (goto-char (nth (random (length headings)) headings))
      (org-reveal))))

(with-eval-after-load "org"
  (define-key org-mode-map (kbd "C-c n R") #'my/org-random-heading))
