Re: [O] heading specific fast keys?

[John Kitchin]

Thanks for the idea. It got me to read how org does it in the first
place ;)

Here is my solution at the moment. I just add a hook to
org-speed-command-hook, define special elfeed fast keys, and then when
on an ELFEED entry, get those first.

This is proof of concept code that works, and defaults to user then
default keys. What a great ecosystem org is!

Happy holidays everyone!

#+BEGIN_SRC emacs-lisp
(defun org-speed-elfeed (keys)
  (when (or (and (bolp) (looking-at org-outline-regexp)
                 (not (null (org-entry-get (point) "ELFEED")))) 
            (and (functionp org-use-speed-commands)
                 (funcall org-use-speed-commands)))
    (cdr (assoc keys(append
                     org-speed-commands-elfeed
                     org-speed-commands-user
                     org-speed-commands-default)))))

(setq org-speed-commands-elfeed
      '(("b" . (lambda (&optional arg)
                 (save-excursion
                   (re-search-forward "Link: *")
                   (org-open-at-point-global))))))
      

(add-hook 'org-speed-command-hook 'org-speed-elfeed)
#+END_SRC
