Function keys, also known as F keys, are a set of shortcut keys located at the top of a computer or terminal keyboard, labeled F1 through F12. These keys are programmed to perform certain functions in a software program or the operating system, making computer tasks more efficient.
For example, the F1 key serves as a help key that provides assistance on using a program, while the F5 key is used to refresh a web page in an internet browser. However, the function of these keys may vary depending on the operating system and software program used.
Function keys on a terminal keyboard can generate short fixed strings, while those on a standard computer keyboard can generate a fixed one-byte code that is outside the normal range and translated by the keyboard driver into another configurable sequence.
Overall, function keys are a useful tool that can make using a computer more efficient with quick and easy access to important commands.
