Auto suggest arrow key navigation

[RRP]

Hi ,

I have developed an auto suggest field. Please refer to the link http://ez.no/community/articles/clean_up_your_applications_using_ajax/google_suggest_like_example_using_html_ajax 

Here they have not given codings for arrow key navigation. I want to navigate the list of pop-up words using Up/Down arrow keys.

Kinldy help me out on this.

thanks in advance ..
