Keyboard Navigation
Keyboard testing reveals focus, ordering, interactive-state, and modal/navigation problems that mouse-only testing can hide.
Core concept
Explain Tab, Shift+Tab, Enter, Space, Escape, arrow-key patterns used by some widgets, visible focus, and focus management in overlays.
Using it in a real interface
Test a navbar dropdown, modal, form, and icon-only button without a mouse. Explain the expected focus path and what should happen when a modal opens and closes.
Implementation notes
Never remove outline or focus indicators without providing an equally clear alternative. Keyboard users need a visible indication of the current control.
