The function keys or F keys are lined across the top of the keyboard and labeled F1 through F12. These keys act as shortcuts, performing certain functions, like saving files, printing data, or refreshing a page.

For example, the F1 key is often used as the default help key in many programs. The F5 key is used in an Internet browser to refresh or reload a web page. The function of these keys can differ with each operating system and software program.
