What is the Accessibility app? What does it do?

Accessibility is a default official app that is not even listed on this help forum’s categories, nor in the official documentation as far as I can tell. “File a Bug” takes me to the Nextcloud Server page.

  • What is this app?
  • Where is the documentation?
  • Can I turn it off? Does it matter?
  • Why would I limit it to specific groups as can be done under settings?

Accessibility enhance the usage and display of nextcloud…

Universal access is very important to us. We follow web standards and check to make everything usable also without mouse, and assistive software such as screenreaders.
We aim to be compliant with the {guidelines} 2.1 on AA level,
with the high contrast theme even on AAA level.

Accessibility provide keyboard navigation, some font options, add highcontrast style for dark mode, and may-add/provide other related features.
