Audit accessibility of the devguide

[willingc]

Audit our devguide for assistive tech and ARIA support.

---

From @hugovk:

Nice little shortcut, but I'm concerned this will interfere with keyboard handling for people using assistive tech such as screen readers.

https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/ includes:

So, screen reader users will commonly expect that pressing the right arrow key will expand a collapsed node.

https://webaim.org/techniques/keyboard/ has examples where ←/→ keys are needed.

For contributors: please note that changes will most likely belong upstream in the Furo theme.

I opened the Furo discussion is here pradyunsg/furo#933

Please, reopen #1784 as it has nothing to do with Furo theme.

@willingc I don't see how this issue is actionable. Do you have a plan in mind? ? What should be the end result in the context of #1784?

I opened #1784 without any accessibility in mind. It is just a common user experience for Linux and terminal users to avoid using mouse if possible - something that Rust people already do with their docs - https://doc.rust-lang.org/book/title-page.html - press right.
