Thanks everyone for the feedback - we ditched the next/previous buttons. I kept a 'start' button at the bottom of the first page because I wanted to set up for the user that it all scrolls down from there, plus I just had to keep a giant button somewhere on the page :)

And good idea about giving some sort of visual cue the keyboard buttons work. I think I might work on something to indicate that. Thanks!
