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.
On this page:
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.
Required development techniques
The following techniques are required to meet Checkpoint 2.3 from the IBM Hardware Accessibility Checklist:
- Provide an option to adjust the key delay before repeat to at least 2 seconds.
- Provide an option to adjust the key repeat rate to at least 2 seconds per character.
Recommended development techniques
The above techniques are required; the following techniques are recommended to enhance accessibility.
- Provide an option to ignore repeated keys.
- Provide an option to set the accept rate (how long the key must be held down before the key is accepted).
Required test techniques
