When a user touches predetermined key buttons among the plurality of key buttons such that the key buttons contact their associated touchpad pieces in a state where a menu screen is displayed, the predetermined key buttons serve as navigation key buttons for changing a menu screen between main menus or shifting a highlight between submenus. Upon detecting a touch-drag for a plurality of key buttons in a menu mode, menu items displayed on the menu screen are sorted or highlight-scrolled according to a predetermined condition for the touch-dragged key button group.
