Desktop computers ooze no fn key.

Pioneer let the exhibition information:The fn key is a unique auxiliary key on the notebook keyboard, the full name of fn in English is: function, Chinese means Chinese, that is, the fn key on the laptop is a function key, used to form a combination of keys with other keys.

The fn key for laptops is in the bottom left corner of the laptop keyboard, and the fn key for most laptops is at the bottom of the bottom left corner of the keyboard. Some laptops have the Ctrl key in the bottom left corner, and the fn in the bottom row of the keyboard from the second from the left.

The fn key is a switch key with 2 different symbols on the same key, and it stands to reason that the fn key is of different colors, so you see which keys on the keyboard have symbols of the same color, and these keys generally have 2 different symbols. So it's very clear, the fn key is used to switch these keys, for example, the arrow keys on your keypad "Up key" has a screen brightness similar to a small sun + symbol, you hold down the fn key, and then keep that "up key", the brightness of the screen goes up, I hope I answered correctly

The fn button is generally seen on the notebook keyboard, and it has no effect when pressed alone, mainly with other keys to achieve certain functions, such as adjusting the volume level, screen brightness, etc.。。。 Desktops don't seem to be common...
