The new interface of Gutenberg has a learning curve, for all users.

For users that depend on assistive technology (AT), like a screen reader or voice recognition software, that learning curve is much higher.
If you don't have an overview of the whole screen or are depended on keyboard focus to perform tasks, Gutenberg is harder to learn.

To help AT users, a manual is needed. With:

• a walk through of the basic functionality with a keyboard only
• how to navigate through functionality with the screen reader navigation
• a list of accessible names for labels that are icons now
• a list of the keyboard short cuts
• a way to report issues or and contribute.

@abrightclearweb already started this and she need help, people who do research on how to use Gutenberg and people that help writing. The work document is on Google Docs
