Questions
Keyboard Navigation Checker FAQ
Why should positive tabindex be avoided?
Positive values create a separate focus order that is difficult to maintain and can conflict with the visual and DOM order.
Do custom controls need tabindex?
A custom interactive element usually needs tabindex=0, the correct role and name, and complete keyboard behavior. A native button, link, or form control is normally preferable.
Can markup analysis detect every keyboard trap?
No. It can identify suspicious patterns, but traps, focus restoration, modal containment, and navigation order must be tested in the running interface.
Which keys should be tested?
At minimum test Tab, Shift+Tab, Enter, Space, arrow keys where the control pattern requires them, and Escape for dismissible interfaces.
Apply the result
From finding to verified fix
Interpret the finding
Static warnings identify markup patterns to test; complete keyboard access depends on focus movement and behavior in the running interface.
Common causes to inspect
- Clickable noninteractive elements
- Positive tabindex values overriding DOM order
- Hidden, disabled, or modal content retaining unexpected focus targets
Practical next steps
- Prefer native interactive elements
- Follow an established keyboard pattern for custom controls
- Test forward and reverse focus, activation, dismissal, and escape paths
What this check cannot prove
Markup analysis cannot operate widgets, observe focus order, detect every trap, or confirm announcements with assistive technology.
