A handheld remote controller device that may be manually programmed while the keypad is conveniently supported in an easy to actuate and readily viewable position in front of a user. Individual keybutton entries are temporarily stored until the entry sequence is complete. Each keybutton entry may be visually displayed for review by the user. When the entry sequence is completed the remote controller device is then aimed at a remotely controlled television set, video tape or video disk player, cable or satellite signal converter. The user initiates a SEND command and the stored entries are retrieved and transmitted from the remote controller device to the receptor of the remotely controlled device as a packet of data which acts to change channel selection or accomplish other tasks in the remotely controlled device. A keybutton entry filter reduces a likelihood for accidental multiple entries which may be caused by tremors and other physical or mental maladies. In this way, physically challenged persons, or elderly persons in particular, may be enabled to utilize a remote control function with less chance for error. When only a single number channel, such as channel 5 is selected, a necessitous leading zero is automatically added to the SEND dispatched command.
