THE “f-numbered” KEYS

The keys F1 through F12, commonly known as the function keys on a computer keyboard are keys programmed to run some certain operating system or application program’s command. The function keys depending on the keyboard or computer may have a variety of uses; a default action or no use at all. The operating system installed on the computer and the application program in use 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. Some keyboards include additional functions on the function keys, which can be activated by pressing the FN key. The additional functions available with the use of the FN key will differ depending on the type and brand of keyboard being used.
