Just noticed a new feature with google search results today, now you can scroll through found search results on the search results page using the arrow keys and just open any search result by pressing enter key.
As shown in the snapshot of the search results page below, you can see the small blue arrow which you can move across the search results.
To open the search result, just move the blue arrow using the up down arrow keys on your keyboard and press enter key.
Do see this feature under your account, do you like this feature ? do let us know through comments.
