Upon the announcement of Google Instant, the company said that they would be rolling out the feature to mobile and browsers (search boxes and Chrome Omnibox) in the next few months. We asked Google how it would work with the browser, and they told us, "It’s premature for us to get into details about future implementations."
We can now see how it works, thanks to a beta developer release, which allows you to enable it. "Just launch your beta/dev/canary release, type about:labs, enable Instant, restart Chrome, and prepare for some interesting browsing," writes Adam Pash at Lifehacker, who provides the following clip, displaying Google Instant functionality from the browser.
It seems to work pretty much how we envisioned it, except it appears to bring up sites from your search history, as well as Google search results, as opposed to search results only.
This week, Google also added Google Instant functionality to more of its search options in the left panel, such as: videos, news, books, blogs, updates, and discussions (no images for some reason).
