I was wondering whether Org-mode can store links to directories, in such a way that C-c C-o‘ing on them would open Dired. I almost asked about it on the mailing list, but I decided to RTFM first. Good decision: it does, though not necessarily in an obvious way. Since [[file:~/path/to/directory/]] tries to open using xdg-open (at least on my Ubuntu box), I tried [[file+emacs:~/path/to/directory/]] and it Just Worked™. Obviously.
