using arrows and tab to select from auto suggest list

I have a form with several text boxes that need to be populated with existing data from a db.  I found a script that uses jquery/css/php to "auto suggest".  I have managed to customize it enough that each box is drawing from a different query.  

Now I would like to make it where I can use keyboard to arrow down the list and then select an item (fill my input box) by using the tab.  

Not sure what Yahoo search assist uses but it works the way I would like mine to work.  

I am not tied to this script, but I know I can make as many input boxes as needed and get the list of hints with it.

Thanks for any help.
