FN Key: Everything You Need to Know
Have you ever looked at the keyboard of your laptop and wondered what that little FN key was for? While it may seem like a mystery, the FN key actually serves a very important purpose.

What is the FN Key?
The FN key is a function key commonly found on laptop keyboards. It is usually located near the bottom left corner of the keyboard, next to the Ctrl key. When pressed in combination with another key, it performs a specific function or action that is assigned to that key.
For example, pressing the FN key and the F1 key may toggle your laptop's sound on or off. Similarly, pressing FN and the F2 key might adjust your screen brightness or enable/disable your wireless network.
How Does it Work?
Each keyboard key has a numeric code associated with it, known as a scancode. When a key is pressed, the keyboard sends the corresponding scancode to the computer. However, when the FN key is pressed, it tells the computer to interpret the next keystroke differently.
For example, if you press the F4 key by itself, it will perform its default function (e.g. closing the active window). But if you first press the FN key, and then press F4, it may perform a different function (e.g. putting your computer to sleep).
Why is it Useful?
The FN key allows you to access a variety of functions and shortcuts that might not be available otherwise. For example, on some laptops, the media controls (play, pause, volume, etc.) are only accessible through the FN key.
Additionally, the FN key can be used to remap certain keys on your keyboard. For example, if you frequently use a certain special character (e.g. the euro symbol), you can remap a less useful key (e.g. the right Alt key) to type that character instead.
Tips and Tricks
Here are a few handy tips and tricks for getting the most out of your FN key:
- Learn the keyboard shortcuts: Familiarize yourself with the different combinations of FN key and other keys on your keyboard. Take note of which shortcuts are most useful to you.
- Customize your shortcuts: If you can't find a function or shortcut you need, consider remapping a key or combination of keys to perform that function.
- Look for labels: Some laptops have labels printed on the keys themselves that indicate what function they perform when used with FN. This can be especially helpful if you're not sure which key to press.
- Use it sparingly: While the FN key can be very useful, try not to rely on it too heavily. Using keyboard shortcuts and other methods can often be faster and more efficient in the long run.
The FN key may seem like a small and insignificant key, but it can actually be quite useful when utilized correctly. With its ability to access a variety of functions and shortcuts, the FN key can save you time and make your computing experience more efficient. So next time you're typing away on your laptop, take a moment to appreciate the power of the FN key.
