;;; Commentary:
|
|
|
|
;; This file implements links to open files in doc-view-mode.
|
|
;; Org mode loads this module by default - if this is not what you want,
|
|
;; configure the variable `org-modules'.
|
|
|
|
;; The links take the form
|
|
;;
|
|
;; docview:<file path>::<page number>
|
|
;;
|
|
;; for example: [[docview:~/.elisp/org/doc/org.pdf::1][Org-Mode Manual]]
|
|
;;
|
|
;; Autocompletion for inserting links is supported; you will be
|
|
;; prompted for a file and a page number.
|
|
;;
|
|
;; If you use org-store-link in a doc-view mode buffer, the stored
|
|
;; link will point to the current page.
