You define function and add it to menu.

My function below uses about: hyperlinks, it decides what to display.

I have defined "about:" hyperlink in `browse-url-handlers' to be:

   '(("gemini:" . elpher-go)
     ("gopher:" . elpher-handler-go)
     ("about:" . hyperscope-about)
     ("hyperscope:" . hyperscope-go)
     ("e2dk://" . amule-handler)))


Then this function is showing About, it has Hyperlinks underline where
it says about:

(defun hyperscope-about (&rest what)
  (interactive)
  (let* ((what (if (eql 'cons (type-of what))
                   (car what)
                 what))
         (what (if (null what) "about:hyperscope" what)))
    (cond ((string= what "about:hyperscope") (hyperscope-text-view "
         ===================================================
         Hyperscope - Dynamic Knowledge Repository for Emacs
         ===================================================
                           about:emacs
                           about:emacs-fancy
                           about:hyperscope
"))
          ((string= what "about:emacs") (about-emacs))
          ((string= what "about:emacs-fancy") (fancy-about-screen))
          (t (hyperscope-text-view "Maybe you wish to read 
about:hyperscope")))))
