This script is definitely the best Google Search results page keyboard-navigator that I've tried (even though others had more installs). I like that it doesn't break normal tabbing through the page (and changes the page very minimally), and that you can move focus to and from the search box. Since I don't have other styles or scripts installed for the google search results pages, I don't have any key conflicts like the previous commenter. I changed my default included pages to URLs of the form "http://www.google.tld/search*", like the Advanced Google Keyboard script.
