[Tutorial Feedback]

Hi!

When running through the tutorial for carousels (
https://www.w3.org/WAI/tutorials/carousels/working-example/), I was having
some trouble with activating the bottom navigation buttons, including the
stop button, using my keyboard. I was attempting to use space and enter,
but these did not work, and I couldn't find anything in the sections before
about alternate keys to use.

Thank you,
Sam
