12. The mobile communication terminal of claim 1, wherein the controller is configured to control the touch screen to scroll the text data displayed on the input window to the left side or the right side when the input window is touched and dragged to the left side or the right side.

13. The mobile communication terminal of claim 1, wherein the at least one soft key is changed to comprise a key for providing a menu for inputting a commonly used word when the touch pad is displayed.

14. The mobile communication terminal of claim 1, wherein the controller is configured to control the touch screen to display on the touch screen a screen comprising a list of commonly used words when a menu key for inputting the commonly used word is selected.

15. The mobile communication terminal of claim 14, wherein the commonly used word is preset by a user.

16. The mobile communication terminal of claim 14, wherein, when one of the commonly used word is selected, the controller is configured to control the touch screen to display the selected commonly used word on the input window.

17. The mobile communication terminal of claim 1, wherein the at least one soft key comprises a soft key for inputting a symbol.

18. The mobile communication terminal of claim 17, wherein, when the soft key for inputting symbols is selected, the controller is configured to control the touch screen to display a screen for displaying a symbol and, when a symbol displayed on the screen is selected, to display the selected symbol on the input window.

19. The mobile communication terminal of claim 1, wherein the controller is configured to control the touch screen to distinguishably display received text data and transmitted text data on the output window with a corresponding one of the first image, the second image, and another image stored in the mobile communication terminal.

20. The mobile communication terminal of claim 1, wherein the memory is configured to store text data, and

the controller is configured to execute an application for retrieving text data stored in the memory when the soft key is touched and to control the touch screen to display a portion of the retrieved text data on the input window upon selection of the portion.
