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 helpful keyboard shortcuts.

If you are a casual computer user, you might not be aware of these function keys and their use. This post will discuss what these keyboard F1 to F12 function Keys do.

Besides these F1-F12 12 function keys, a unique Fn key is next to the Ctrl key on your keyboard. The Fn key activates special Function Keys marked by unique icons in the same color.

For example, the F1 key on my laptop’s keyboard has a small icon of the Touchpad Off in a color code matching the Fn Key, which means Fn+F1 will turn my Touchpad Off/On. Function keys work differently on different programs.
