How do I use keyboard to browse this?I'm not actually asking for myself, I shared this with someone to get feedback, and they asked why they couldn't use the keyboard; I tried clicking various places that should set the focus on the page, but it always doesn't go anywhere for any keyboard input (arrows would be nice along with page up page down).
Doesn't that then require they also have an account?
Click on the "Make Your Own Copy" link on the top right. After that, you should be able to use keyboard navigation, edit the notebook, evaluate it, etc.
