What Are Function Keys and Why Do They Matter?
Understanding Function Keys (F1–F12)
Function keys are the top row keys on a standard keyboard that perform specific tasks based on the operating system and active application. Unlike standard letter or number keys, function keys execute shortcuts that reduce manual effort, making tasks faster and more efficient.
