[jQuery] [Tooltip] How to implement an fadeIn and fadeout?


Hi!
I use the tooltip from here:
http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/
I use Jquery 1.2.3 and wish to know how to implement an fadeIn and
fadeOut into it.
I use this code:
<script type="text/javascript">
//<![CDATA[
$(function() {
    $('.specials-title').tooltip({
        track: true,
        delay: 0,
        showURL: false,
        showBody: " - ",
        extraClass: "specials-title",
        fixPNG: true,
        left: -92,
        top: -110
    });
});
//]]>
</script>
Thx for your help and time.
Regards,
Dominique
