Keyboard navigation refers to the ability to use a computer keyboard to interact with and control software applications, websites, and operating systems without relying on a mouse or other pointing device. This method of interaction is crucial for accessibility, allowing individuals with motor impairments or visual disabilities to effectively use technology. It is also a skill that can significantly improve efficiency for many users, enabling faster task completion through keyboard shortcuts and logical tab order.

The fundamental principle behind keyboard navigation is the ability to move focus between interactive elements such as buttons, links, form fields, and menus. This is typically achieved using the Tab key to move forward through elements and Shift+Tab to move backward. The Enter key or Spacebar is then used to activate or select the currently focused element. Arrow keys are often employed for navigating within menus, lists, or more complex structures like tree views.

Effective keyboard navigation relies on a well-structured user interface. Websites and applications should have a logical tab order that follows the visual flow of content. Interactive elements must be focusable, meaning they can receive keyboard input, and should visually indicate when they are in focus. Developers must ensure that all functionality accessible with a mouse is also accessible via the keyboard. This practice not only enhances usability for those who need it but also contributes to a more robust and universally accessible digital experience for everyone.
