- ;; INSTALLATION ======================================================
-
- ;; To use this file, byte-compile it, install it somewhere in your
- ;; load-path, and put:
-
- ;; (autoload 'find-dired "find-dired" nil t)
- ;; (autoload 'find-name-dired "find-dired" nil t)
- ;; (autoload 'find-grep-dired "find-dired" nil t)
-
- ;; in your ~/.emacs, or site-init.el, etc.
-
- ;; To bind it to a key, put, e.g.:
- ;;
- ;; (global-set-key "\C-cf" 'find-dired)
- ;; (global-set-key "\C-cn" 'find-name-dired)
- ;; (global-set-key "\C-cl" 'find-grep-dired)
