billentyzetnavigálhatóság

Keyboard navigation, sometimes referred to in Hungarian as billentyűzet navigáció, is the practice of interacting with a user interface using a keyboard rather than a pointing device. It covers how users move focus between interactive elements, how they activate controls, and how the interface communicates state to keyboard users. The goal is to make all essential functions reachable without a mouse.

Common patterns include moving focus with the Tab key to advance and Shift+Tab to move backward, activating focused controls with Enter or Space, and using arrow keys to navigate within menus or lists. Esc typically exits dialogs or menus, and Alt or Ctrl combinations may access menu bars or shortcuts. In web interfaces, elements are made focusable with native HTML controls or the tabindex attribute, and a visible focus indicator helps users track where the keyboard focus lies.

Accessibility considerations are central to keyboard navigation. It is a fundamental requirement of many accessibility guidelines, including WCAG, which mandate that website and application functionality be operable via keyboard. Good practice includes restoring focus to a logical element after interactions, avoiding focus traps in dialogs or modals, providing skip links, and ensuring clear, descriptive focus outlines and labels.

Implementation and design guidelines emphasize predictable focus order, consistent behavior across components, and proper focus management in dynamic content. Designers and developers should test with real keyboard input, support common shortcuts, and ensure that all critical functions remain accessible to users who rely on the keyboard as their primary input method.
