 ;; A calculator for Emacs.

 ;; whatever), when you have Emacs running already?

-;; `calculator' to a key and make it an autoloaded function, e.g.:
-;;   (autoload 'calculator "calculator"
-;;     "Run the Emacs calculator." t)
+;; You can bind this to a key by adding this to your Init file:

 ;;   (global-set-key [(control return)] 'calculator)
