[jQuery] Accordion and external controls

[zac]

I have a accordion menu that expands and contracts with mouse over:

$("dd").hide();
var overFn = function(){
     $("dd:visible").slideUp("slow");
     $(this).parent().next().slideDown("slow");

};

// hover delay
var outFn = function(){};
        $("dt a").hoverIntent({
    over: overFn,
        sensitivity: 3,
    interval: 130,
    out: outFn
});

I have another set of links on the page and I was wondering how I
could add an on-click function that expanded the appropriate part of
the accordion?  This one is calling it by the parent but say the top
hidden accordion is giving the class dd.one ... and the link
controlling it is a.linkone

$("dd.one").hide();
        $("a.linkone").click(function(){
        How do I replace this:
 $(this).parent().next().slideDown("slow");
      with this functionality
 $("dd.one").slidedown("slow");
   ??
        return false;
        });
