Thanks -- the site looks for the scrollwheel and the down arrow, both of which will open the tutorial after which page down et al. should work as expected. Are you seeing different behavior or just wanted to hit page down initially?

I'm referring specifically to the state before the pane is activated. It feels awkward to have so few options to activate it. The transition/animation also toys a bit with scrolling up/down.
