I use org goto to jump quckly to headings, but the other day
I forgot the name of the heading, but I remembered its contents.
I thought it could be useful if I could navigate org files by content
too, so I quickly created this package as a sunday afternoon fun.
It is a wrapper around the multi-occur interface, so you can
simply type your search pattern and the occur results from your org
buffers are updated dynamically as you type.
Here it is:
;;; org-occur-goto.el -- search open org buffers with an occur interface
;;; Usage: M-x oog, then start typing
;;;
;;; select from the occur matches with up/down/pgup/pgdown and press enter
;;;
;;; the search string must be at least 3 characters long (by default)
;;;
(require 'cl)
(defvar oog-idle-delay 0.5)
(defvar oog-minimum-input-length 3)
(defvar oog-map
(let ((map (copy-keymap minibuffer-local-map)))
