A method for indicating status on a programmed communication device wherein each of one or more backlights is associated with a respective key of a plurality of keys. Status information to be communicated to a user of the communication device is then generated, and one or more backlights are illuminated according to a pattern corresponding to the status information. Thus, a visual graphical display is not necessary, cost is reduced, volume is conserved, and reliability is increased.
