Bind arrow keys to navigation
It would be nice if I could keyboard navigate to the "Next" page with the right arrow key, etc.
I would try adding this feature myself, but I'm afraid there are too many moving parts with JS in script tags, JS from JS Core, and React.
Good idea.
But, total speculation: what if some interactive (like MathJax Explorer) wanted that key also and had the focus?
The behavior of the key should be that of the interactive thingy if focus is within that thingy.
In normal webpage use, the up/down arrow keys will scroll the page up and down. Now imagine some element is tall, but constrained in height, and has overflow:scroll. When focus gets inside that thing, up/down changes to scrolling up and down within that thing. So I reckon it should be a bit like this when something smaller wants the left/right keys too.

I do find that sometimes a table in PTX is rigidly too wide for a small screen, and horizontal scrolling comes into play. And then there would be conflict between using left/right for that scrolling and for page navigation.

Just to make sure that any such navigation doesn't mess up slides, which inherit some conversion stuff from html - presumably js as well? The way that is supposed to work is inherited from reveal.js right, as far as I have observed.

A more conventional case: typing in any kind of input field, the arrow keys should do their usual thing, not take you to a new page.
