Scrolling with the keyboard is broken on the second edition (I did not try the first edition) of the Rustlang book.
For users without a mouse (either broken like mine, or have some other reason for not using a mouse) must be able to navigate with the keyboard. Normally the up/down arrows and the page up and page down keys allow scrolling on webpages.
In Firefox 52 at least, these keyboard shortcuts are broken on version two of the rust book, making navigation very difficult. Left/Right change pages, but once you are on a page you cannot scroll.
