 **Keyboard operability** refers to the ability to use all features and navigate digital content (websites, software, applications) entirely via the keyboard, without requiring a mouse or touch interface. This is a crucial requirement for:

- People with **motor disabilities** who cannot use a mouse
- People who are **blind or have severe visual impairments**, relying on [**Screen reader****s**](https://nitsantech.de/en/accessibility-glossary/screen-readers)
- Users who prefer or need **assistive technologies** such as alternative input devices (e.g., sip-and-puff systems, mouth sticks)

A fully keyboard-operable website allows the user to:

- Move through menus, forms, buttons, modals, and sliders using the **Tab**, **Arrow**, **Enter**, and **Space** keys
- Access **all content and interactions** (including dropdowns, pop-ups, etc.) without getting stuck
- See **clear visual focus indicators** that show where they are on the page

Keyboard operability is a fundamental requirement under standards like [**WCAG**](https://nitsantech.de/en/accessibility-glossary/wcag) **2.1** (Success Criterion 2.1.1) and the **BITV 2.0** in Germany. It ensures equal digital participation and is part of legal accessibility compliance.

**Testing** for keyboard operability involves navigating a site using only the keyboard, identifying any elements that cannot be accessed or operated.
