Question

What are the F1 through F12 keys?

Answer

Commonly known as "function keys", F1 through F12 may have a variety of different uses or no use at all. Depending on the installed operating system and the software program currently open will 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.
