In some programs, the function of a standard command and an alternate command may be the same (for example, F1 typically displays Help for the active window, and on some keyboards, the alternate command for F1 is also Help). Use the Fn key. On keyboards with an Fn key, hold down Fn and press the key to use the alternate commands.
