Renato,

This sounds like autoload to me: info '(elisp) Autoload'.

>From the *info*: 

     This function defines the function (or macro) named FUNCTION so as
     to load automatically from FILENAME.

Here's an example.

File ~/tmp/aaa.el:
    (defun blah ()
      (interactive)
      (message "Congratulations! M-x blah is now loaded."))

Now, in your *scratch* buffer evaluate the following:
(autoload 'blah "~/tmp/aaa.el" "Demonstrate autoloading." t nil)
(local-set-key "\M-\C-Y" 'blah)

The key sequence M-C-Y will now run the command blah, loading it if necessary.
