If keyboard shortcuts are implemented using only a letter (including upper- and lower-case letters), punctuation, number, or symbol characters, provide a way to turn off or remap character key shortcuts:
- Turn off: A mechanism is available to turn the shortcut off;
- Remap: A mechanism is available to remap the shortcut to use one or more non-printable keyboard characters (e.g. Ctrl, Alt, etc);
- Active only on focus: The keyboard shortcut for a user interface component is only active when that component has focus.
If you provide character key shortcuts, provide a way to turn them off and a way to remap them. When remapping, allow users to assign one or more characters to the shortcut.
