A terminal has an input area that supports touch input, and a controller for responding to the touch input area. The controller also displays selected symbols in the touch input area responsive to an operational mode of the terminal. When the terminal is in a call mode, a command or data associated with one of the symbols displayed for the call mode may be entered by touching the symbol, touching and dragging the symbol from its original location, or touching and dragging the symbol to a central area.
