Currently not able to add Element field is forms 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 Forms with keyboard. Maybe also consider adding help text for keyboard guidance.
- Go to Content > Forms
- Add a New Form
- Attempt to add a field using keyboard
Admin user is able to add a Field into the structure and save using just a keyboard
