The function of the “Fn” key is almost the same as the “Shift” button, where its use is usually combined with other keys on the keyboard.

What is the function of Fn key in Keyboard?

Like the “Shift” and “Ctrl” keys, the “Fn” key has its own functions. However, it should be noted beforehand, the “Fn” button has different functions depending on the type of keyboard and laptop you have. Below are the most common uses for the “Fn” key that can be found on laptops or PCs.

Increase or Decrease the Computer Speaker Volume

Usually, we increase and decrease the volume via the speaker icon in the right corner of the screen, right? Well, besides using the mouse and shifting the volume settings on the screen, we can also use the Fn key.

Above is an example of an external keyboard image (additional keyboard), and you can see the Fn key is between the Ctrl key and the key with the Windows logo. As for the row of the F keys (F1-F10), at the bottom of the F key, there is a symbol.

Suppose you want to increase the volume, press the Fn button and without releasing it, also press the F9 button (because there is a speaker symbol and a ‘+’ sign at the bottom of the F9 button).

If you want to decrease the volume, you can press the Fn button at the same time pressing the F8 button (because in the image there is a speaker symbol and a ‘-‘ sign). This function can be different on different keyboards or laptops, depending on the symbols on the F1-F10 or F12 keys.

Turning off the Speaker

Besides increasing or decreasing the speaker volume of your laptop or computer, the Fn button can also be used to turn off the speaker volume (mute). Still using the keyboard image above as an example, to turn off the speaker volume, you can press Fn and F7 simultaneously.

Turn on MP3

Still referring to the image above, you can even turn on the music player on your computer. But this function returns to each keyboard, yes. With reference to the image above, you can press the Fn button at the same time as the F3 button.

There are many uses for the Fn key and they all differ depending on the symbols found on F1-F12. This time, we will describe the use of the Fn key based on certain laptop brands.
