Your typical Windows keyboard is divided into several parts such as the function keys, the main typing keyboard or typewriter keys, the directional keys, and the numeric keypad, among others.

Each of these keys has its own function. But, although the F-keys are in the front row of the keyboard, they have taken a somewhat back seat, and are rarely used because not many people know their functions.

In this article, we will walk you through the function keys, what they are, and their key functions. So, the next time you hear about function keys, it won’t sound like Greek to you.

So, what are function keys?

The function keys are the keys from F1 to F12 (or on some keyboards, F19) located at the top of your keyboard. You can use them for a variety of things, from getting help to controlling your media volume, among others.

Function keys can act alone and perform some single key actions, e.g. F5 To refresh a page. They can work in conjunction with modifier keys such as Ctrl, Shift, and Alt to perform specific commands.

Function keys are also programmable, meaning any developer can configure them to work in any way they want within the program or software.

Most keyboards also display action icons above some function keys to let you know what that key does when pressed, while others don’t. The latter may leave you in the dark, but not now.

Let’s now go over each function key and most of their individual functions.
