An electronic device according to one aspect includes a touch screen including a first key region to which a plurality of first keys are allocated and a second key region to which a plurality of second keys are allocated; and at least one controller configured to execute character input processing based on operations onto the first key detected in the first key region and the second key detected in the second key region of the touch screen, wherein the first key region is a region extending along a first rim of the touch screen, the plurality of the first keys is arranged along the first rim, the second key region is a region extending along a second rim of the touch screen which is different from the first rim, and the plurality of the second keys is arranged along the second rim.

A non-transitory computer readable medium includes a character input system including a first band-shaped key area displayed including the characters of character groups including representative characters lined up one by one. When a touch point is detected in this area, a second band-shaped key area is displayed including the characters of the group including the representative characters lined up at that detection position. When movement of a touch point from the first band-shaped key area to the second band-shaped key area is detected, a band-shaped candidate area is displayed including candidate character strings matching the characters in a line at that movement position. These areas are arranged in the width direction and with their orientations aligned. When the touch point disappears after moving from the second band-shaped key area to the band-shaped candidate area, the candidate character string displayed at that disappearance position is confirmed as the input character string.

A control section allows a screen of a display section to display a plurality of numeric keys, detects a touch gesture on the individual numeric key through a touch panel to allow an input of a numeric number corresponding to the numeric key subjected to the touch gesture, and detects an action on each of hard keys to accept an instruction to perform a function corresponding to the hard key subjected to the action. When a predetermined action is performed on one or more individuals of the hard keys, the control section assigns numeric numbers to the respective hard keys and detects an action on the individual hard key to allow an input of the numeric number corresponding to the hard key subjected to the action.
