When Chris searches for something, he wants to be able to just use the arrow keys to select results, but it won't let him do that. Leo says that's the CSS. He can provide his own style sheet that would include this if he wants, but in order to do that he'd have to learn the syntax of CSS. If he searches for this problem and "CSS," there's probably somebody who has written his or her own style sheet. Then he can just download that and change the settings to use his instead. This could be helpful to someone who can't use a mouse.
Neo in the chatroom has found a Chrome extension called Google Search Keyboard Shortcuts that will do what Chris is asking.
