;; screen-at-a-time scrolling, and doesn't remap any of the keyboard
;; commands to do it.
;; You can disable autoloading of this package by placing
;; (setq crisp-load-scroll-lock nil) in your .emacs before loading
;; the crisp package. If you want to use this package by itself,
;; you can enable it by placing the following in your .emacs:
;; (require 'scroll-lock)
;; In the first (autoloaded) case, meta-f1 is bound to the command to
;; toggle the scroll-lock mode. In the second (non-autoloaded) case,
;; you can enable and disable it with the 'scroll-lock-mode' command.
;; You can enable and disable this mode with the 'scroll-all-mode' command.
