How can keyboard accessibility be achieved?

Achieving keyboard accessibility primarily revolves around ensuring that all functionalities are accessible via the keyboard in a logical manner. This means that users who rely on keyboard navigation can interact with all elements of a website or digital application without needing to use a mouse, which is crucial for individuals with mobility impairments or various disabilities.

When keyboard accessibility is implemented correctly, every actionable element—such as links, buttons, and form fields—should be reachable and operable using keyboard commands (like the Tab key for navigation and Enter or Spacebar for activation). Moreover, the focus order should follow a logical progression that aligns with the visual layout of the interface, providing a seamless experience for the user.

The other options do not promote effective keyboard accessibility. Relying solely on mouse access excludes a significant portion of users who cannot use a mouse. Limiting tab features restricts navigation and could hinder access to important content. Finally, providing no focus indicator does not support users in tracking their position within the interface, which can lead to confusion and frustration for those navigating with a keyboard.
