javascript programming jquery keystrokes

I'm working on a module that implements site-wide keystrokes. Keystrokes may execute specific actions on the site, like clear cache, show logs, etc... The reference is this project: http://rikrikrik.com/jquery/shortkeys/), and comments written here http://groups.drupal.org/node/1592#comment-5721 and below.

The initial release of this module simply shows javascript alert when you press specific keys on your keyboard. It sends an Ajax GET request and returns an output to the user.
