Here's a quick Lightroom tutorial on a great little Lightroom secret you might not know about, Lights Out Viewing Mode.
It's a great way to quickly check out how your photo looks without having any distractions clouding what you're seeing in Lightroom. I'll show you the Lightroom keyboard shortcuts too, so click the play button and enjoy!

If you don't have Adobe Photoshop Lightroom 2, Amazon usually has the best price.
