1. A mobile terminal configured to execute a plurality of functions, comprising: a touch panel display; and circuitry configured to control the touch panel display and to respond to touching of the touch panel display, wherein: the circuitry configures the touch panel display to display: a plurality of functional icons, each of which is associated with one or more of the plurality of functions that are actions the mobile terminal is configured to perform, at least one of the plurality of functions including a phone function, the plurality of functional icons being displayed in a functional icon palette; a plurality of incoming event icons, each of which is associated with an incoming event triggered by an incident other than user input and with one of the plurality of functions, the plurality of incoming event icons being displayed in an incoming event icon palette separate from the functional icon palette; and a destination icon, and the mobile terminal is configured such that: upon the circuitry detecting when one of the functional icons is dragged from the functional icon palette into a first region which is a designated area of the touch panel display and, without overlapping with any icon, is tapped or released by a user on the touch panel display, the mobile terminal executes a first function with which the one of the functional icons is associated, and upon the circuitry detecting when the one of the functional icons is dragged from the functional icon palette and overlapped with the destination icon within the first region on the touch panel display, the mobile terminal executes a second function with which the one of the functional icons is associated.
