What Are the Function (F1, F2, etc) Keys on My Computer Keyboard for?

Introduction

Computer keyboards have undergone many changes over the years. Initially, they only had a few function keys, but more function keys were added as technology evolved. Today, computer keyboards have a dozen (or more) function keys that perform different tasks. If you’re having trouble figuring out what the function keys do on your computer keyboard, you’re not alone. This article will explain what each of the function keys does on a standard keyboard in both Windows and macOS.

What Are Function Keys?

Many keyboards have a set of dedicated keys that are not part of the QWERTY keyboard. These “function” keys are typically F1, F2, F3, etc., and are usually found in a row across the top of the keyboard. They allow you to perform different functions with your computer. For example, pressing F1 will open the help menu, and pressing F8 will put your computer into full-screen mode. The purpose of each function key is specific to your operating system and software that you use, so there can be a wide variety of functions associated with each of the function keys. Still, there are some common uses across platforms.
