Mouseable text in Emacs.
Modern people using modern Emacs usually look at screens marked up with font-lock (aka syntax highlighting). Sometimes modern people even use a mouse.
This package provides
button-lock: a programmer-friendly library for making text mouseable
wiki-nav: a user-friendly library for making text mouseable
Because these packages are based on font-lock, they are efficient.

(require 'wiki-nav) (global-wiki-nav-mode 1) ;; Sprinkle double-bracketed [[links]] in your code comments
Button-lock uses font-lock to make text clickable. In Emacs-speak: it creates font-lock keywords which have mouse bindings added to their text properties.
Button-lock has a simple interface that works like this
(button-lock-set-button "http://google.com" 'browse-url-at-mouse)
However, button-lock does not create any buttons by default. You must write some Lisp code to make it do anything.
For much more information, see the source for button-lock.el
and the docstring for
button-lock-set-button (C-h f button-lock-set-button).
Wiki-nav is a user-friendly high-level interface to button-lock. It provides a minor mode which recognizes [[wiki-style]] double-bracketed navigation links in any type of file. Wiki-nav links permit the user to jump between sections, between files, or open external URLs.

load-pathdirectory. If you've never heard of a
load-pathdirectory, create a new directory named
~/.emacs.d/lisp, and add this code to your
(add-to-list 'load-path (expand-file-name "~/.emacs.d/lisp"))
Add the following to your
(require 'wiki-nav) (global-wiki-nav-mode 1)
in your files. That's it. There's more functionality, but simple
[[links]]may be all you need. When you click on
[[links]], the point jumps forward in the buffer to the next matching wiki-nav link.
Bracketed links may contain external URLs:
Or they may use various internally-recognized URI schemes:
visit:navigates to another file
func:navigates to the definition of a function
line:navigates to a line number
visit:may be combined with other schemes:
Path names and similar strings are subjected to URI-style unescaping before lookup. To link to a filename which contains a colon, substitute "%3A" for the colon character.
For much more information, see the source for wiki-nav.el
and the docstring for
wiki-nav-mode (C-h f wiki-nav-mode).
