Feature: Add right/left n/p keyboard navigation to all Python docs

Describe the enhancement or feature you would like

Right now the accessibility audit https://github.com/python/devguide/issues/1792 is blocking keyboard navigation https://github.com/python/devguide/pull/1784 not only for devguide, but across Python ecosysem https://github.com/orgs/sphinx-doc/discussions/14406 https://github.com/sphinx-doc/sphinx/pull/14408 https://github.com/readthedocs/sphinx_rtd_theme/pull/1686 https://github.com/pradyunsg/furo/discussions/932

Clearly, other projects may not have the resources to access the risk of hurting sensitive auditory, so all maintainers just don't take it - and while Sphinx comes with keyboard shortcuts, no project across Pyto ecosystem enables it.

Now that there is a chance to do accessibility study, please make sure that both arrow keys and vim `style n/p keys are evaluated for usage, with official "documentation accessibility" chapter, that could be easily referenced for other projects to follow.

Thanks for your time, folks.

Commencez par examiner l’audit d’accessibilité lié, la pull request de navigation de devguide et les discussions de l’écosystème Sphinx afin de comprendre les risques mentionnés et les approches existantes. Définissez la portée du chapitre consacré à l’accessibilité de la documentation officielle et la manière dont la navigation avec les touches fléchées et la navigation de style vim avec n/p doivent être évaluées dans les projets de documentation Python ; la finalisation doit fournir des recommandations auxquelles d’autres maintainers pourront se référer.
