www.smobnology.com/2015/07/what-are-f1-through-f12-keys.html?m=0 Commonly known as function keys, F1 through F12 may have a variety of different uses or no use at all. The operating system installed on the computer and the software program currently open can change how each of these keys operate. A program is capable of not only using each of the function keys, but also combining the function keys with the ALT or CTRL key. For example, Microsoft Windows users can press ALT + F4 to close the program currently active. Note: Some keyboards include additional functions on the function keys, which can be activated by pressing the FN key, usually located near the CTRL key, and the appropriate function key. The additional functions available with the use of the FN key will differ depending on the type and brand of keyboard being used. If your keyboard does not have a row of function keys, they are probably set up as secondary functions on other keys. Some laptop keyboards are set up this way to save space. They can be activated by pressing another key plus the key with the secondary F key functionality. Below is a short-listing of some of the common functions of the functions keys.
