What is Keyboard Navigation?
Keyboard navigation refers to the ability to navigate and interact with a website or web application using only a keyboard, without the need for a mouse. This functionality is critical for keyboard-only users, including people with motor impairments, visual impairments, or those using assistive technologies.
Common keyboard keys used:
- Tab – move forward through interactive elements
- Shift + Tab – move backward
- Enter – activate buttons or links
- Arrow keys – scroll or move within menus
- Space – toggle checkboxes or buttons
Example: A user presses Tab to jump from the search field to the navigation menu, then presses Enter to activate a dropdown.
Why Keyboard Navigation Matters in Web Accessibility
Keyboard accessibility is a core requirement of WCAG (Web Content Accessibility Guidelines) and is enforced under laws like:
- ADA (Americans with Disabilities Act) in the U.S.
- BFSG (Barrierefreiheitsstärkungsgesetz) in Germany
- EN 301 549 in the EU
According to WCAG 2.1, every user must be able to operate all functionalities using only a keyboard. This includes navigation, form inputs, dropdowns, modals, sliders, and menus.
Without keyboard support, your site is not accessible—and may be legally non-compliant.
How to Support Keyboard Navigation (TYPO3, WordPress & More)
If you're working in TYPO3, WordPress, or another CMS, here’s how to make your site keyboard-friendly:
- ✅ Use semantic HTML – Elements like <button>, <a>, <input> are naturally keyboard-accessible.
- ✅ Maintain a logical tab order – Structure your layout so tabbing follows a natural, intuitive flow.
- ✅ Use :focus styles – Always show a visible indicator (like an outline) when an element is focused.
- ✅ Avoid tabindex="-1" unless necessary – This removes elements from tab order.
- ✅ TYPO3 Tip: Use accessible templates and the Accesstive Extension to audit navigation.
- ✅ WordPress Tip: Choose “Accessibility Ready” themes and test navigation with only a keyboard.
Always test without a mouse to ensure full interaction, from navigation to form submissions.
Common Mistakes & Misconceptions
Here are the frequent issues to avoid:
❌ “If it works with a mouse, it’s fine.”
✔️ No. Mouse users and keyboard-only users experience sites differently. Accessibility requires both.
❌ “Keyboard users are a small group.”
✔️ Not true. Many users rely on keyboard interaction, temporarily or permanently, due to injury, disability, or preference.
❌ “Tabbing is only for forms.”
✔️ Wrong. All interactive content, including menus, modals, and sliders, must be keyboard accessible.

Key Takeaway
If your website can’t be used with a keyboard, it’s not accessible.
Keyboard navigation is essential for digital inclusion and accessibility compliance. By designing with keyboard users in mind, you’re building a better experience for everyone.
Integrate accessibility considerations from the design phase rather than treating it as an afterthought Use tools like Access Assistant, Access AI Audit, Access Monitor, and Access Accy.
