For quick jotting down one can use the remember.el module of emacs. Simply add the following to your ~/.emacs:
(setq org-directory “~/data/orgs/”)
(setq org-default-notes-file (concat org-directory “/notes.org”))
(define-key global-map “\C-cr” ‘org-remember)
Obviously you need to adjust the paths accordingly. As you can see Ctrl-c r will bring up a remember window where you’ll be able to jot down ideas. As it automatically loads the org mode, you can make use of all its features while making a note. Once you’re done, simply press C-c C-c to save the note in the org directory (in my case it’s ~/data/orgs/notes.org). The entry will start with the date of note creation and the first line of the note as a kind of the title.
edit: I realise there’s so much more to ‘remember’ than I’ve posted here. I’ll look into it in the near future.
