Abstract: A mobile electronic device includes a touch panel, a display unit, and a CPU that displays a key on the display unit and, when a key group of a soft keyboard that has a plurality of keys arranged within a predetermined area is displayed on the display unit, the CPU displays, in a switchable manner, first arrangement in which each key of the key group is arranged within the predetermined area and second arrangement in which at least one of the keys of the key group is deleted or arranged in a size smaller than that of a key that is in the first arrangement and that corresponds to the one of the keys and in which a handwriting input area is arranged at a space area that is generated within the predetermined area as the one of the keys is deleted or arranged in a smaller size.

Abstract: When a French character is selected while an English character string candidate is presented, a mobile terminal presents English and French character string candidates by using an English/French mixed candidate dictionary. Furthermore, when a French character is selected while English and French character string candidates are presented by using the English/French mixed candidate dictionary, the mobile terminal presents a French character string candidate by using a French candidate dictionary. Moreover, when a character other than French is selected while a French character string candidate is presented by using the French candidate dictionary, the mobile terminal presents an English character string candidate by using an English candidate dictionary.
