Currently not able to add web content structure field with keyboard only because adding a field is through drag and drop. Hitting Tab key to navigate does not cycle over the fields to add. So it doesn't feel intuitive and possibly impossible to create Web Content Structure with keyboard. Maybe also consider adding help text for keyboard guidance.
- Go to Content > Web Content > Structures
- Add a structure
- Attempt to add a field using keyboard
Admin user is able to add a Field into the structure and save using just a keyboard
