If key repeat is supported, the delay before repeat shall be adjustable to at least 2 seconds. Key repeat rate shall be adjustable to 2 seconds per character.


Rationale

When key repeat is supported, a user with a mobility impairment may not be able to remove pressure from a key fast enough to prevent the key repeat function from initiating. Similarly, when they do want a key repeated, they may need a slower repeat rate.
