You’ll notice that searching is faster and more interactive from your first keystroke. As soon as you begin to type, Google Instant starts to display results, so you don’t even need to press the search button.
Once you pick a web page to visit, you’ll see the page load on a new, slide-in pane that will layer over the search results. You can slide the pane to the right to get back to your search results, and even keep scrolling through the results as your web page is loading. This allows you to go back and forth from results to web pages quickly to get the information you are looking for.
