Source Code

;; Defined in /usr/src/emacs/lisp/view.el.gz
;;; Commands that enter or exit view mode.

;; This is used when view mode is exited, to make sure we don't try to
;; kill a buffer modified by the user.  A buffer in view mode can
;; become modified if the user types C-x C-q, edits the buffer, then
;; types C-x C-q again to return to view mode.
