The F12 Function Key

The Function Keys on every keyboard range from F1 to F12. However, the older computer sets used to have these keys grouped on the left side of the keyboard. In general, these function keys are on the top row. While each function key has a unique purpose, these keys may also be used with the Alt and Ctrl Command keys to create practical keyboard shortcuts. You might be unfamiliar with these keyboard function keys when using a computer. Nonetheless, only the F12 key will be discussed in this article. We'll soon give you access to more function keys.

A brief reminder: Besides the F1 through F12 function buttons, your keyboard has a unique Fn key adjacent to the Ctrl key. Special Function Keys are identified by unique icons of the same color and are activated by pressing the Fn key. For instance, the F6 key on my laptop's keyboard has a little symbol for the Touchpad Off in the same color as the Fn Key, so pressing Fn+F1 will toggle my Touchpad On/Off. Different programs have different ways of using function keys. So, let's begin by pressing the F12 key.

A function key called F12 may be near the top of practically every computer keyboard. The key is typically used to launch the debugging tools for Firebug, Chrome, and other browsers.

For instance, to hit F12 on an Apple computer, hold down the fn key and press F12. Now that you know where the F12 key stands and where it is located, you will see how to use it on various media.
