What Is Keyboard Accessibility? Completing Tasks Without a Mouse
Keyboard accessibility means users can complete core tasks with Tab, Shift + Tab, Enter, Space, and arrow keys without relying on a mouse.
Key Takeaways
- Keyboard accessibility means a site works without a mouse.
- Interactive controls must be reachable, visible when focused, operable, and escapable.
- It is one of the highest-priority checks before release.
Why it matters
Many users rely on keyboards, alternative input devices, or assistive technologies. If the main flow only works with a mouse, those users are blocked.
What to check
Keyboard testing should walk through the main task, not only isolated controls.
- Logical tab order.
- Clear visible focus.
- Operable buttons, links, menus, and dialogs.
- No keyboard traps.
