There's a hint? I still can't find it.

No, I'm not trolling. No indication that scrolling does anything, there's even a footer at the bottom of the page. Then _when_ i scroll nothing happens for a while until i scroll far enough.

There is one in the top right corner (underneath the language part) for me. Although it does seem to disappear whenever you start scrolling.
