Beyond Instant results: Instant Previews

Official Google Blog: Beyond Instant results: Instant Previews: "Instant Previews provides a graphic overview of a search result and highlights the most relevant sections, making finding the right page as quick and easy as flipping through a magazine.

To use it, click once on the magnifying glass next to the title of any search result and a visual overview of the page will appear on the right. From there, hover your cursor over any other result to see a preview. For those of you who’ve recently stopped using your mouse to search, now you can navigate to a result, hit the right arrow key to see the preview, and hit the down arrow key to keep browsing."
