Keyboard Navigation
Keyboard navigation is a web accessibility and user interface concept that enables users to interact with digital interfaces using only keyboard inputs, such as Tab, Arrow keys, Enter, and Escape, without relying on a mouse or touch. It ensures that all interactive elements (like links, buttons, and form fields) are reachable and operable through sequential keyboard focus, often following a logical tab order. This is crucial for users with motor disabilities, screen reader users, and power users who prefer keyboard shortcuts for efficiency.
Developers should learn and implement keyboard navigation to comply with accessibility standards like WCAG (Web Content Accessibility Guidelines), which require keyboard operability for all functionality. It is essential for building inclusive applications that serve users with disabilities, such as those who cannot use a mouse due to physical limitations. Additionally, it enhances the user experience for power users who rely on keyboard shortcuts for faster navigation in productivity tools, code editors, or complex web forms.
