Keyboard-Only Navigation: The Accessibility Standard Millions of Developers Overlook

Keyboard accessibility is far more critical than most developers realize—2.5 million Americans with motor disabilities cannot use a mouse. WCAG 2.2 establishes clear operability standards for keyboard navigation, focus indicators, and focus trapping, yet common implementations fail on basic requirements. By understanding these standards and testing properly, developers can ensure their applications are truly accessible, avoiding legal liability while reaching users who would otherwise be completely excluded.
