keyboardoperated

Keyboard-operated refers to systems, interfaces, or devices that can be controlled primarily through keyboard input rather than a pointing device. It encompasses software interfaces that can be fully navigated and operated using keys for navigation, activation, and commands. Many implementations rely on modifier keys such as Shift, Ctrl, and Alt to extend shortcuts, along with function keys and key combinations.

In software, keyboard operation is central to efficiency and accessibility. Common mechanisms include keyboard focus management, tab navigation, arrow keys for movement, Enter or Space to activate controls, and a range of keyboard shortcuts. Terminals, text editors, integrated development environments, and many command-line tools are designed to be keyboard-operated. Games and multimedia applications may also offer keyboard-centric modes. In hardware contexts, some devices are designed to be controlled directly through keyboards, such as embedded systems, programmable keyboards, or virtual keyboards on touch devices.

Accessibility and design considerations emphasize keyboard operability as a core requirement. Guidelines like the Web Content Accessibility Guidelines stress operability, including visible focus indicators, logical focus order, avoidance of keyboard traps, and the ability to perform all functions via keyboard. Designers should avoid mandatory reliance on a mouse for essential actions and provide alternative input methods where needed. Clear focus cues and support for skip navigation help users move efficiently through complex interfaces without a pointing device.
