25 ;; How to install ws-mode.el:
26 ;;
27 ;; either you
28 ;; put the following line into your default.el (usually
29 ;; /usr/local/emacs/lisp/default.el):
30 ;; (autoload 'wordstar-mode "ws-mode.el" "WordStar emulation mode." t)
31 ;; put ws-mode.el into a directory in your Emacs load-path (usually
32 ;; /usr/local/emacs/local/lisp).
33 ;;
34 ;; or you
35 ;; put ws-mode.el into your directory $HOME/lib/emacs (or something
36 ;; like that)
37 ;; put the following two lines into your file $HOME/.emacs
38 ;; (autoload 'wordstar-mode (expand-file-name "~/lib/emacs/ws-mode.el")
39 ;; "WordStar emulation mode." t)
40 ;;
41 ;; You can then invoke wordstar-mode for a buffer by typing
42 ;; M-x wordstar-mode
43 ;;
44 ;; If you want to use Emacs in wordstar-mode by default, put the
45 ;; following line in addition into your file $HOME/.emacs :
46 ;; (setq default-major-mode 'wordstar-mode)
47 ;;
48 ;; If you want to use Emacs *always* in wordstar-mode, even when the
49 ;; file type would indicate another mode, put the follwoing line in
50 ;; addition into your file $HOME/.emacs :
51 ;; (setq auto-mode-alist nil)
52 ;;
53 ;; Enjoy!

58 "Major mode with WordStar-like key bindings.

60 BUGS:
61 - Help menus with WordStar commands (C-j just calls help-for-help)
62 are not implemented
63 - Options for search and replace
64 - Show markers (C-k h) is somewhat strange
65 - Search and replace (C-q a) is only available in forward direction
66
67 No key bindings beginning with ESC are installed, they will work
68 Emacs-like.
