scrolling .html page to xy?

i was wondering if anyone knew where to get the javascript code for a script that will scroll a page to x/y coordinates?
i have a page that is around 2000 pixels wide and it has a horizontal scrollbar, i want to put in next/back links that will scroll the page forward/backwards to certain x/y coordinates.

any ideas?
i have seen it done before, but i have no idea where i saw it.

[PHP]
function scrollBastard(x,y){
window.scrollBy(x,y)

*or*
window.scrollTo(x,y)
}

*and link it like this*

[/PHP]

etc etc.. not 100% sure, haven't got the time to test it, but I'm pretty sure that's the way...........

i'll give it a try and report back. thanks
