Keyboard key test.
Keyboard key testing is the process of checking whether all the keys on a keyboard are functioning properly. This typically involves pressing each key and verifying that the corresponding character appears on the screen or that the expected reaction happens. Key testing is crucial for ensuring that a keyboard is in good working condition and that its users are able to get the most out of it. It's often used by computer technicians, programmers, and gamers who rely heavily on their keyboards for work or entertainment.
