|

|
|
;;
|
||
|
|
;; This file implements the minor mode `mlinks-mode' that create
|
||
|
|
;; hyperlinks for different major modes. Such links can be visible or
|
||
|
|
;; invisible. The meanings of the links are defined per mode.
|
||
|
|
;;
|
||
|
|
;; Examples:
|
||
|
|
;;
|
||
|
|
;; - In in html style modes the links are visible they can mean either
|
||
|
|
;; open a file for editing, go to an achnor or view the link in a
|
||
|
|
;; web browser etc.
|
||
|
|
;;
|
||
|
|
;; - In emacs lisp mode the links are invisible, but maybe highlighed
|
||
|
|
;; when point or mouse is on them. (Having them highlighted when
|
||
|
|
;; point is on them can be a quick way to check that you have
|
||
|
|
;; spelled a symbol correct.) The meanings of the links in emacs
|
||
|
|
;; lisp mode are go to definition.
|
||
|
|
;;
|
||
|
|
;; Common to links that open a buffer in Emacs is that you can the
|
||
|
|
;; buffer opened in the same window, the other window or in a new
|
||
|
|
;; frame. The same key binding is used in all major modes for this.
