A keyboard has long been the conventional input device to terminals and personal computers. Most of the keyboards used t have a set of programmable function (PF) keys which were hard labeled with PFn (n is an integer index for the PF key) on the top of the keyboards. Each program has its own set of commands for the user interface. They are usually defined in a profile to map each command into a corresponding PF key. Moreover, each user is able to define his own mapping of the PF keys. The flexibility of the use of the PF keys is a trade-off for the complexity of the many PF key settings. The use of these PF keys for each program is totally dependent on the user's memorization. This PF key interface is inconvenient and unreliable to many users.
