[jQuery] Cycle plugin prev/next question

[atomk]

The code shown below is working fine for me, but I want the prev and
next buttons to jump 2 slides instead of 1. I think this involves the
"prevNextClick" option, but don't know how to code it...

<script type="text/javascript">
       $(function() {
    $('#liberiaSlideshow').cycle({
        fx: 'fade',
        delay: 1000,
        speed: 'slow',
        timeout: 3600,
        timeoutFn: calculateTimeout,
        prev: '#prevButton',
        next: '#nextButton'
    });
});


Thanks!
