I just released a plugin last week called Quick Navigation Interface, and I think it solves this problem in a better way, and also solves the larger issue of being able to quickly get to any area in wp-admin.

You just hit the ` key, and it brings up an interface where you can type whatever you want to browse to, and as you type it'll show you the closest matches, then you just hit enter to open that link. It works with any screen, post, page, custom post type, etc in wp-admin.
