heading specific fast keys?

heading specific fast keys?

[John Kitchin]

I wondered if anyone know a straight forward way to make
heading-specific fast keys in org-mode.

The idea is if I am on a heading that is a "contact" (which means it has
an EMAIL property), then there would be special hot keys for it, e.g.
"e" would compose a message, "u" might open a URL if it had one, etc...

Or, on entries captured from elfeed, I could just press "b" to open the
entry in a browser, etc...

I guess there would need to be some kind of hook that looks up a keymap
or something on these special positions. And maybe a default map for
non-special headings.

Thoughts?

Possible synergy from one of the approaches to [MultipleModes](https://www.emacswiki.org/emacs?search=%22MultipleModes%22)

I use polymode in org-mode to good effect within which switches mode with code blocks to be language specific.

It might suggest an architecture....

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
