Hardware checklist

Checkpoint 2.1: Toggle key status

Provide the status of all locking or toggle keys visually and either through touch or sound.

Rationale

Toggle keys, like the Num Lock, Caps Lock and Scroll Lock keys on the keyboard typically provide only a visual indicator of the key state. A user who is blind or visually impaired cannot determine the state of those keys. The status should be provided in redundant ways so a deaf user can see the state and a blind user can hear or feel the state. If the state is available to software, an assistive technology can access the state and announce when the toggle key is on or off.
