Google's Instant, a new feature that predicts search queries as people type them and refreshes results and ads accordingly on the fly, will be extended to 12 new countries, bringing the total to 19 countries.

Instant is also gaining keyboard navigation capabilities, which let users move among search results and back into the search box for query refinements without having to reach for their mouse.

Marissa Mayer, Google's vice president of search products and user experience, made the announcement on Wednesday at the TechCrunch Disrupt conference in San Francisco, which is being webcast.

The domain expansion and the new features will be rolled out over the coming days. That Google is giving the technology a boost like this so quickly could indicate the company has been happy with its adoption.
