What does keyboard accessibility entail?

Keyboard accessibility primarily involves ensuring that all functionalities of a website or application can be accessed and navigated using a keyboard alone, without the need for a mouse. This is crucial for users who may have physical disabilities that prevent them from using a mouse, as well as for individuals who prefer keyboard navigation for efficiency.

By making sure that all interactive elements—like forms, buttons, and menu items—are navigable through keyboard commands, designers and developers can create a more inclusive environment. This adherence to keyboard accessibility is a key principle of web accessibility guidelines, such as the Web Content Accessibility Guidelines (WCAG).

The other options do not align with the principles of keyboard accessibility. For instance, insisting on mouse interactions contradicts the fundamental notion of accessibility. Avoiding shortcuts can actually hinder accessibility, as many users with disabilities rely on keyboard shortcuts for efficient navigation. Finally, limiting keyboard accessibility to only certain web applications ignores the need for universally accessible design, which should be a concern for all web projects, regardless of their specific function.
