Abstract

An electronic device includes a display, an input device, and a controller. The display displays a character input screen. The input device includes character input keys, a character delete key, and a confirmation key. When the controller detects a character input key being pressed, the controller causes a character corresponding to the character input key to be displayed on the character input screen and determines whether or not any word registered in a word table is predictable from an unconfirmed character or a character string of unconfirmed characters input of which has not been confirmed through the confirmation key. In response to a single press on the character delete key, the controller deletes a deletion start character that makes word prediction impossible, or the deletion start character and at least one unconfirmed character immediately preceding or following the deletion start character.
