how to store a elisp procedure in a file and recall it typing a key

[renato.pontefice]

Hi,
I would store, the piece of code made in elisp, and recall it by pressing a some special key:
i.e.
my elisp procedure does a control on the file where it is executed, so if I open a text file, I would made that control on that file.
How can i recall it?
I do not find the way, asking togoogle :-(

What? :)

You want to put Elisp code in a file, and then execute
if from Emacs?

Or from the shell?

I don't understand what you want to do. (I'm pretty
sure what you want to do is possible, though.)

Try the Emacs documentation itself first -- in this case, the "Writing
Defuns" node of the Emacs Lisp Intro manual seems to be the best place
to start.

Here's a starting point (in case it's not obvious, you would store this
in your ~/.emacs file):

(defun my-command ()
   "Does a control on the current buffer."
   (some-elisp-function)
   (some-other-elisp-function and-its-argument and-its-other-argument))

(global-set-key "\C-ca" 'my-command)

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.
