I love efficiency. And keyboard shortcuts fall right into that "holy crap she's a dork, and efficient!" category. That's why I just downloaded LaunchBar. It's a productivity utility that lets you navigate pretty much anything on your computer with a few keystrokes. You get instant access to your applications, documents, contacts, bookmarks, iTunes, search engines and even a calculator. All you have to do is know what short abbreviations to type in.
I'm still working on them.
