How to access jcarousel properties

How to access jcarousel properties

Sorry if this is a stupid question, but I'm quite new to javascript and jQuery. Being used to Perl, Bash and the like, these javascript objects confuse me.

How can I read and set the animation property of my carousel?

I have tried something like this:

jQuery('#ij-carousel').jcarousel({
animation: 2500,
  //[...]   initCallback: function(jc, state) {   if (state == 'init') {      $('div.jcarousel-next').bind('click', function() {       speed = jc.animation; //save auto-animation speed
// jc.animation = 'fast';
        jc.next(); // jc.animation = speed; //restore auto speed
        return false;
      });
      jc.play();
   }
});











(Basically, I want to have slow auto-scroll animation, but a fast animation when the Prev/Next buttons are deliberately clicked).

Thanks for any help...
