jquery keyboard shortcut plug from scroll from absolute div to div

Mike Hostetler's great plugin here ->

http://mike-hostetler.com/jquery-keyboard-navigation-plugin

is almost exactly what I 开发者_如何学Goam looking for. The only other option I'd like is to have the up and down arrow keys, instead of just triggering the default area, scroll to the div in question. are there any plugins that do this?

thanks so much in advance!

here's a demo of what i am working on to give you a better idea - http://bedepressed.org/history/sample.htm
