Is there a package or setting to show an org-mode link (under cursor - without using the mouse) destination in the modeline or other area of Emacs window? It would be nice to have instead of doing C-c C-l to look at it each time.
Try this:
(defun link-message ()
(let ((object (org-element-context)))
(when (eq (car object) 'link)
(message "%s"
(org-element-property :raw-link object)))))
(add-hook 'post-command-hook 'link-message)
