28 | ;; Keybindings and minor functions to duplicate the functionality and |
29 | ;; finger-feel of the CRiSP/Brief editor. This package is designed to | |
30 | ;; facilitate transitioning from Brief to (XE|E)macs with a minimum | |
31 | ;; amount of hassles. | |
5e33ba39 | 32 | |
7aa5f6cf KH |
33 | ;; Enable this package by putting (require 'crisp) in your .emacs and |
34 | ;; use M-x crisp-mode to toggle it on or off. | |
5e33ba39 | 35 | |
7aa5f6cf KH |
36 | ;; This package will automatically load the scroll-all.el package if |
37 | ;; you put (setq crisp-load-scroll-all t) in your .emacs before | |
38 | ;; loading this package. If this feature is enabled, it will bind | |
39 | ;; meta-f1 to the scroll-all mode toggle. The scroll-all package | |
40 | ;; duplicates the scroll-alling feature in CRiSP. | |
5e33ba39 | 41 | |
7aa5f6cf KH |
42 | ;; Also, the default keybindings for brief/CRiSP override the M-x |
43 | ;; key to exit the editor. If you don't like this functionality, you | |
44 | ;; can prevent this behavior (or redefine it dynamically) by setting | |
45 | ;; the value of `crisp-override-meta-x' either in your .emacs or | |
3da6cc26 RS |
46 | ;; interactively. The default setting is t, which means that M-x will |
47 | ;; by default run `save-buffers-kill-emacs' instead of the command | |
48 | ;; `execute-extended-command'. | |
5e33ba39 | 49 | |
d21b2085 RS |
50 | ;; Finally, if you want to change the string displayed in the modeline |
51 | ;; when this mode is in effect, override the definition of | |
52 | ;; `crisp-mode-modeline-string' in your .emacs. The default value is | |
53 | ;; " *Crisp*" which may be a bit lengthy if you have a lot of things | |
54 | ;; being displayed there. | |
55 | ||
5e33ba39 RS |
56 | ;; All these overrides should go *before* the (require 'crisp) statement. |
