[CS4] Scrollbar with onKeyPress buttons ~ Help!

Hi! I’m relatively new to Actionscript and all…

Is there anyway possible to take the “Simple Custom Scrollbar” on the Kipura site (http://www.kirupa.com/developer/flash8/scrollbar.htm)

and make it so that the “UP” and “DOWN” keys on your keyboard also scroll the scrollbar?

Thank you!
