tangentbordsnavigerbar

tangentbordsnavigerbar (keyboard-navigable) describes a user interface property in which all interactive elements can be reached and operated using a keyboard alone, without a mouse. Users navigate by the Tab key to move focus between controls, activate controls with Enter or Space, and use element-specific keyboard commands where appropriate. A tangentbordsnavigerbar interface also provides a visible focus indicator to show which element currently has focus.

Ensuring keyboard navigability is a central aspect of digital accessibility. Guiding standards such as the Web Content Accessibility Guidelines (WCAG) include criteria for operability with a keyboard (2.1.1 Keyboard) and for maintaining a logical focus order (2.4.3 Focus Order) along with a visible focus indicator (2.4.7 Focus Visible). These principles apply to websites, applications, and progressive web apps.

Implementation practices include using semantic HTML elements (buttons, links, input fields) and avoiding or properly handling custom widgets that rely solely on mouse interaction. Focus management is essential when opening dialogs, changing content dynamically, or performing navigation. Minimize the use of tabindex to preserve a natural focus order, provide skip links, and ensure that all custom widgets expose keyboard shortcuts and accessible roles. Design should ensure that focus remains visible and controllable.

Testing for tangentbordsnavigerbar involves keyboard-only use, verifying that every functionality is reachable and operable. Tests should cover multiple browsers and assistive technologies, check for focus traps in modals, and confirm that the visual focus indicator matches the logical focus sequence. When implemented well, keyboard navigability improves usability for all users.
