What do Keyboard F1 to F12 Function Keys do

Every keyboard has a set of Function Keys F1-F12 on the top row, however, the old computer sets used to have these keys gathered on the left side of the keyboard. While every function key caters special function, these can also be combined with Alt Keys and Ctrl Command keys to make the useful keyboard shortcuts. If you are a casual computer user, you might not really be aware of these function keys and their use. In this post, we will talk about what do these keyboard F1 to F12 function Keys do.

Besides these F1-F12 12 function keys, there is special Fn key located next to Ctrl key on your keyboard. The Fn key is used to activate special Function Keys which are marked by special icons in the same color. For example, key F1 on my laptop’s keyboard has a small icon of Touchpad Off in a color code matching to the Fn Key; which means Fn+F1 will turn my Touchpad Off/On. Function keys work differently on different programs.
