For example, I defined it as: -; (setq find-file-hooks (list -; (function (lambda () -; (if (not (or (eq major-mode 'Info-mode) -; (eq major-mode 'vi-mode))) -; (vi-mode)))))) -; 3) In your .emacs file you can define the command "vi-mode" to be "autoload" -; or you can execute the "load" command to load "vi" directly. -; 4) Read the comments for command "vi-mode" before you start using it. -; -; COULD DO -; 1).
