A portable and usually handheld remote controller for accepting manual entry of acronymical as well as decimal input data urged through a keypad and converting the submitted input data into channel number selection data which is sent via wireless command to a channel selection receiver, such as a television set. The remote controller is particularly suited for accepting a program content provider's acronym, such as NBC and converting it, usually through an intermediate decimal entry step represented by keypad equivalent decimal values such as 622 and finally into a variously presetable channel selection decimal value such as 07 which is subsequently sent via the wireless command for effectuating a television channel selection uniquely designated by any particular service provider's virtual or real channel number assignments.
