Success Criterion 2.1.2 "No Keyboard Trap" is a Level A requirement under the "operable" principle of WCAG 2.2. EN 301 549 clause 9.2.1.2 maps this criterion for procurement conformance.
Correct: Tab into any component and Shift+Tab, Escape, or arrows always get you out — modals release focus on close. Incorrect: focus stuck inside an iframe widget or a rich-text editor with no documented exit. Embedded third-party widgets are your trap too — if a user cannot leave a captcha or editor by keyboard alone, the page fails.
Engine coverage: partially automated (audit tier 2) — automated findings flag candidates; a clean VPAT claim still needs the documented manual check.
