I hadn't been aware of lisp:// URLs until you mentioned them.

So, I looked up planner-lisp.el:

  | ;;; Commentary:

  | ;;; Code:

  | (require 'planner)
  | 
  | ;;;###autoload
  | (defun planner-lisp-browse-url (url)
  |   "If this is a LISP URL, jump to it."
  |   (when (string-match "^lisp:/*\\(.+\\)" url)
  |     (eval (read (concat "(call-interactively '" (match-string 1 url) ")")))
  |     t))

That looks like a pretty nifty hack, but I'm not sure what types of
thing one would use this for.

I'd appreciate it if someone enlightened me.


Thanks,
