When the CPU displays a ten key group in which a plurality of column key groups each including a plurality of keys in a column are arranged side by side on the display, the CPU displays in a switchable manner a first arrangement of the keys in which the keys in the ten-key group have the same width and a second arrangement of the keys in which keys in a center column key group arranged between a right-side column key group and a left-side column key group have a larger width than the keys in the right-side column key group and the left-side column key group. ## Claims ### Claim 1 A mobile electronic device comprising: a display that comprises a touch panel function; and a processor that displays a key on the display, wherein when displaying an operation key group in which a plurality of column key groups each including a plurality of keys in a column are arranged side by side on the display, the processor displays in a switchable manner a first arrangement of the keys in which the keys in the operation key group have the same width and a second arrangement of the keys in which a predetermined key or keys in a column key group arranged between a right-side column key group and a left-side column key group in the operation key group have a larger width than the keys in the right-side column key group and the left-side column key group. ### Claim 2 (depends on 1) The mobile electronic device according to claim 1, further comprising: a sensor that detects a tilt of the mobile electronic device, wherein the processor displays an operation key group on the display, in which the first arrangement and the second arrangement are switched to each other according to the tilt of the mobile electronic device detected by the sensor. ### Claim 3 A mobile electronic device comprising: a display that comprises a touch panel function; and a processor that displays a key on the display, wherein when displaying an operation key group on the display in which a plurality of column key groups each including a plurality of keys in a column are arranged side by side on the display, the processor displays in a switchable manner a first arrangement of the keys in which keys in the operation key group are arranged one for each and a second arrangement in which a right-side column key group in the operation key group is arranged on the right side of a display area and a left-side column key group in the operation key group is arranged on the left side of the display area and a predetermined key or keys in a column key group arranged between the right-side column key group and the left-side column key group are arranged both on the right side of the display area and on the left side of the display area. ### Claim 4 (depends on 3) The mobile electronic device according to claim 3, further comprising: a sensor that detects a tilt of the mobile electronic device, wherein the processor displays an operation key group on the display, in which the first arrangement and the second arrangement are switched to each other according to the tilt of the mobile electronic device detected by the sensor. ### Claim 5 A computer-readable recording medium having stored therein a key display program for a mobile electronic device that comprises: a display that comprises a touch panel function, and a processor that displays a key on the display, the key display program causing the processor to execute a process comprising: when displaying an operation key group in which a plurality of column key groups each including a plurality of keys in a column are arranged side by side on the display, displaying in a switchable manner a first arrangement of the keys in which the keys in the operation key group have the same width and a second arrangement of the keys in which a predetermined key or keys in a column key group arranged between a right-side column key group and a left-side column key group in the operation key group have a larger width than the keys in the right-side column key group and the left-side column key group. ### Claim 6 A computer-readable recording medium having stored therein a key display program for a mobile electronic device that comprises: a display that comprises a touch panel function, and a processor that displays a key on the display, the key display program causing the processor to execute a process comprising: when displaying an operation key group in which a plurality of column key groups each including a plurality of keys in a column are arranged side by side on the display, displaying in a switchable manner a first arrangement of the keys in which keys in the operation key group are arranged one for each and a second arrangement in which a right-side column key group in the operation key group is arranged on the right side of a display area and a left-side column key group in the operation key group is arranged on the left side of the display area and a predetermined key or keys in a column key group arranged between the right-side column key group and the left-side column key group are arranged both on the right side of the display area and on the left side of the display area.
