- ;; DESCRIPTION:
- ;;
- ;; This module defines an implicit button type and associated action and
- ;; help types. A press of the Action Key on a unified resource locator
- ;; (URL) displays the referent for the URL. A press of the Help Key on a
- ;; URL displays a history list of previously browsed WWW documents. Press
- ;; the Action Key on any item from the history list to display it.
- ;;
- ;; This requires the Emacs W3 World-Wide-Web browser available from:
- ;; "/anonymous@cs.indiana.edu:/pub/elisp/w3".
- ;;
- ;; It assumes that you have set up to have w3 auto-loaded according to the
- ;; setup instructions included with W3. Specifically,
- ;; 'w3-follow-url-at-point' should be autoloaded.
- ;;
- ;; DESCRIP-END.
