Ensure that keyboard shortcuts consisting of typing a single key do not interfere with the user’s assistive technology (AT).
Why this matters
Read Understanding Success Criterion 2.1.4: Character Key Shortcuts by the W3C for information on this issue.
How to implement
- Ensure that users have a way to turn off single-key shortcuts.
- Ensure that users can change character-key shortcuts. The remapping mechanism should include non-printing characters. The alternative shortcuts could be longer strings of up to 25 characters that would directly serve as native speech commands for any speech engine.
