11.2.1.16: No keyboard trap

Where ICT is non-web software that provides a user interface, it shall satisfy the success criterion in Table 11.16.

Table 11.16: Software success criterion: Document success criterion: No keyboard trap

If keyboard focus can be moved to a component of the software using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away.

NOTE 1: Since any part of a software that does not meet this success criterion can interfere with a user's ability to use the whole document, all content in the document (whether or not it is used to meet other success criteria) shall meet this success criterion.

NOTE 2: Standard exit methods may vary by platform. For example, on many desktop platforms, the Escape key is a standard method for exiting.

NOTE 3: This success criterion is identical to the WCAG 2.0 Success Criterion 2.1.2 No Keyboard Trap replacing "page" and "Web page" with "document", removing "See Conformance Requirement 5: Non-Interference" and with the addition of note 1 above.
