[jQuery] news rotator - looking for some help in cleaning up my code

[sperks]

I've got my code working (adapted of Karl Swedberg's Scroll Up News
Reader) http://docs.jquery.com/Tutorials:Scroll_Up_Headline_Reader,
but I'm sure there's a cleaner (more dynamic) way of checking where I
am in the loop so that I don't have to do all the individual click
checks
        $("#topStoryButtons li a:eq(0)").click(function() {
        $("#topStoryButtons li a:eq(1)").click(function() {
        $("#topStoryButtons li a:eq(2)").click(function() {
        $("#topStoryButtons li a:eq(3)").click(function() {

I think I'm just looking for a way to capture the instance of the link
I'm clicking and pass that variable on. Any help appreciated - Steve
