Bleacherreport has a function on their website that lets you browse between stories with arrow keys. While that is nothing spectacular, I would like to understand how they do so AND change the URL in the address bar in the browser.
It's one thing to load up new content via AJAX, but I've never seen it done alongside refreshing the URL. There is also a slide to the left animation from one content to the next.
