I'm going to use jquery for this because I absolutely love it...Also, please upload jquery to your own site if you use this.
Code:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#vidLinks a,#vidLinks2 a,#vidlinks3 a,#vidLinks4 a').bind('click',function(){
jQuery('a.currently').removeClass('currently');
jQuery(this).addClass('currently');
})
}
);
</script>
<style type="text/css">
a.currently{
background-color: gray;
}
</style>
Oh, and I didn't test this.
