Keys that act as shortcuts for performing certain functions such as saving files or printing data. Function keys usually are lined along the top of the keyboard labeled F1 through F12. Below is a picture of the Saitek Gamers' keyboard, which gives an example of where the function keys are often located on the keyboard.
Note: In the past, earlier Apple Macintosh computers did not have function keys and some early IBM computer keyboards had two rows of function keys, with the second row containing F13 - F24.
Tip: The function keys should not be confused with the Fn (function) key found on laptop computer keyboards.
