Keyboard navigation refers to the ability to move through and interact with digital content, such as websites, software, or applications, using only a keyboard, without the need for a mouse or touchscreen. This is essential for individuals with mobility impairments, vision loss, or those who rely on assistive technologies like screen readers. Common keyboard controls include the Tab key to move between interactive elements (like links, buttons, and form fields), Shift + Tab to move backwards, and Enter or Space to activate selections. For digital platforms to be accessible, all functionality should be operable using a keyboard alone. Poorly designed interfaces that rely solely on a mouse can exclude users with specific needs. Ensuring effective keyboard navigation is a key part of meeting accessibility standards such as the Web Content Accessibility Guidelines (WCAG), helping create a more inclusive digital environment for all users.
