Ask HN: What happened to Google's keyboard navigation?

When Google Instant was introduced, they also added a feature where a little blue arrow was shown next to the top result, and you could use the up/down keys on the keyboard to navigate the other results in the page. This was a cool feature for several reasons, the best one being that you could do a Google search and "click" the link you wanted without using the mouse at all (just hit enter on the link you want)! But a day or two ago this disappeared. Does anyone have any news on this decision? Will it come back? It was a great feature and I'd be really sad to see it go.
