Official Google Blog: “With Google Instant you get results as fast as you type, but your search doesn’t stop there. Once you get results back, you choose a site to visit based on the information in each result—like the title, a snippet of text and the URL. Over time we’ve made steady improvements to our search results and snippets to help you pick a great page. Now we’re making a leap to image-based snapshots—a new kind of visual search result we call “Instant Previews” which makes it even faster to choose the right result. 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.”
