A communication device (100) incorporates a programmable function button (105) that operates in conjunction with a display (102). The button (105) operates in an execution mode when engaged for a time period less than a particular threshold (310, 320, 330, 340), and operates in a programming mode when continuously engaged for a time period greater than the threshold (310, 320, 330, 350). In the execution mode, the button causes execution of a preprogrammed function (340). When in the programming mode, continuous engagement of the button causes a successive presentation of a selectable programmable function on the display (410, 420, 430), and disengagement of the button automatically results in the button being programmed with the selectable programmable function (440, 450). Preferably, release of the button, when in programming mode, also causes automatic execution of the selectable programmable function (460).
