Google announced some new features for Google Instant. They haven't released it for the browser or for mobile yet, but they have added some desktop functionality.
First off, they have added keyboard navigation, so you can use Google Instant without touching your mouse, should you choose to do so. The navigation lets you scroll through Google's search suggestions to bring up more instant results.
Secondly, Google Instant has now been added to more of Google's search options in the left panel, including Videos, News, Books, Blogs, Updates, and Discussions. For some reason, Images is not included.
Google also announced that Google Instant is rolling out in the domains for 12 new countries, including: Austria, Belgium, Canada, the Czech Republic, Ireland, Mexico, the Netherlands, Poland, Slovakia, Slovenia, Switzerland and Ukraine.
Google Instant was available for seven countries until now.
