You specified the PHP tag. Perhaps you meant to use the JavaScript tag? — Lix, May 06 '12 at 11:47

Your question is fairly vague, but you sound like you want to use the arrow keys from within Javascript. This has been asked before: Binding arrow keys in JS/jQuery.

jQuery would also make your AJAX requests a lot easier to write. For examples, see the documentation of jQuery.get().

It's difficult to tell you how to write the Javascript to select a specific item (like in Google), because that depends on what is returned by the AJAX request (xmlhttp.responseText).
