Superfish.js show active page in menu

Hello, I have a simple superfish menu on my site and I'm wondering if there is a way to add a quick line that shows the 'current' page the menu is point to? thanks!

this is a wordpress site, I noticed an example  http://users.tpg.com.au/j_birch/plugins/superfish/#sample4 
i'm getting closer?!
