When i insert phrases into chrome's address field, i often insert search phrases instead of actual address. And i often write same phrase many times over a period of time to go to the same page google that finds. It would be a speed up if i could write a phrase (or a part of it in case of correct autocompletion) and press some key combination to go directly to the last site i visited after entering that search phrase into google's engine. That would be a good use of user data usage tracking and a real measurable benefit from collecting user's data. And that would be a performance improvement on the google's engine itself, because it would reduce query number to google's server using cashe instead.
