I cannot unbind the key
M-l in org-mode.
When the cursor is in an org-mode buffer, I tried to eval (
(unbind-key "M-l" org-mode-map) ;; ^^^ from bind-key.el (define-key org-mode-map (kbd "M-l") nil)
C-h k M-l always says:
M-l runs the command org-demote-subtree (found in org-mode-map), which is an interactive compiled Lisp function in ‘org.el’. It is bound to M-l, C-c C->, <normal-state> M-l.
Same problem for other keys, e.g.
C-k. I also use bind-key.el for other bindings, in case that is of interest.
