Keyboard Accessibility Testing: Can Users Complete the Task Without a Mouse?

Keyboard accessibility is a core part of web accessibility testing. Check tab order, focus indicators, traps, dialogs, and form flows.


Summary

  • If users cannot complete the main task without a mouse, the site has a serious accessibility risk.
  • Keyboard testing checks reachability, visible focus, state changes, and escape paths.

Testing steps

Start at the top of the page and complete the main flow using only the keyboard.

  • Use Tab and Shift + Tab.
  • Confirm visible focus.
  • Use Enter or Space for buttons, menus, and disclosures.
  • Confirm dialogs can be entered, used, and closed.
