WCAG 2.1 - SC 2.1.4 Character Key Shortcuts

Summary:

Check ability for user to remap or disable basic keyboard shortcuts.

Details:

When a page has shortcuts that can be activated using a single key, such as a letter, number, punctuation, or symbol key without a modifier key, the user should have the option to reconfigure (remap to use a modifier) or deactivate (turn off) the shortcut. This standard is not applicable when the control that has the shortcut is focused. This standard does not apply to access keys, as those shortcuts require a modifier key.

When key shortcuts without modifiers are used, speech users may accidentally activate shortcuts while dictating or navigating a page using voice input. Motor-impaired users may also physically hit keys that activate shortcuts unintentionally.
