| 20 ;; DESCRIPTION: | |
| 21 ;; | |
| 22 ;; This module defines an implicit button type and associated action and | |
| 23 ;; help types. A press of the Action Key on a unified resource locator | |
| 24 ;; (URL) displays the referent for the URL. A press of the Help Key on a | |
| 25 ;; URL displays a history list of previously browsed WWW documents. Press | |
| 26 ;; the Action Key on any item from the history list to display it. | |
| 27 ;; | |
| 28 ;; This requires the Emacs W3 World-Wide-Web browser available from: | |
| 29 ;; ftp://cs.indiana.edu/pub/elisp/w3/. | |
| 30 ;; | |
| 31 ;; It assumes that you have set up to have w3 auto-loaded according to the | |
| 32 ;; setup instructions included with W3. Specifically, `w3-fetch' should be | |
| 33 ;; autoloaded. | |
