The "F-Lock" key on a Windows keyboard is also called the "function lock." This key, when enabled, allows you to use the secondary functions of many of the keys on your keyboard. This key is not something that is permanently enabled on most keyboards. Typically, you must hold the key down in order to use the secondary function of your desired keyboard key. The secondary functions of keys are always printed on the keys themselves.
