9.2.16: No keyboard trap

Where ICT is a web page, it shall satisfy WCAG 2.0 Success Criterion 2.1.2 No Keyboard Trap.

WCAG 2.0 success criterion: No Keyboard Trap

If keyboard focus can be moved to a component of the page 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: Since any content that does not meet this success criterion can interfere with a user's ability to use the whole document, all content on the Web page (whether or not it is used to meet other success criteria) must meet this success criterion.
