TL, DR
Laptop keyboards have dual-function keys. For instance, on my Dell G15 laptop, which I use with Ubuntu, the F1 key doubles down as mute for audio output. In some cases you may want to reverse the working of the fn key.
The simple and easy way to do it is to press fn and esc at the same time. Each time you press this combination you will reverse the functioning of the fn key. This means that, alternatively, you will be able to mute the volume or press F1 without pressing the fn key.
That’s all folks!
