How to Find a Keyboard Trap in a Website Checkout

11/10/2026

A keyboard trap occurs when a user navigating without a mouse cannot move focus away from a checkout control, dialog, or embedded widget. It can prevent completion even when the page looks correct.

What to check

Test the full checkout using Tab, Shift+Tab, Enter, Escape, and visible focus. Check modal open and close behavior, validation errors, and whether focus returns to the launching control.

Recommended next step

Fix focus management and retest the complete flow with keyboard and assistive technology. Informatix Systems can assess website accessibility and implementation issues.
