Although it seems backwards to assign a function to a key as opposed to assigning a key to a function, it allows more than one key to perform a particular function; this is useful on cocktail-style arcade cabinets, where more than one set of controls is available. In the default control map file, CONTROLS.INI, all possible key assignments are shown but only keys actually in use are required to be present in the file.
If you do not assign a function to a key, that function will not be available. On a coin-operated jukebox, for example, you would probably not want to assign the BTN_SKIP and BTN_RADIO functions.

The jukebox input engine supports up to four joysticks or gamepads in Windows and two in DOS. Up to 14 buttons can be accessed per stick. Note that in DOS a standard PC gameport only supports two buttons per stick.
