3. The method of claim 2 , wherein the at least one application icon is configured by a user.

4. The method of claim 1 , wherein the application list is configured by a user.

5. The method of claim 1 , further comprising:

displaying, at the display, a dividing line separating the first area and the second area based on the first input.

6. The method of claim 1 , wherein each of the first input and the second input comprises one of a touch input that is generated by a user's finger or a touch input that is generated by an electronic pen.

7. The method of claim 1 , wherein the first execution screen comprises at least one of a home window or an application window corresponding to an application selected by a user.

8. A mobile communication device comprising:

a display; and

at least one processor configured to:

control the display to display a first execution screen of a first application in a full screen,

receive a first input dividing the first execution screen into a first area and a second area, the first input comprising a line drawn across the first execution screen, and the first area being larger or smaller than the second area,

split the display into a first window of a first predetermined size and a second window of a second predetermined size in response to the first input,

control the display to display at least a part of the first execution screen on the first window when the display is split into the first window and the second window,

control the display to display an application list on the second window when the display is split into the first window and the second window,

receive a second input for selecting an application from the application list,

control the display to display a second execution screen related to the selected application on the second window in response to the second input, and

distinguish a type of input tool between the first input and the second input.

9. The mobile communication device of claim 8 , wherein the application list comprises at least one application icon.

10. The mobile communication device of claim 9 , wherein the at least one application icon is configured by a user.

11. The mobile communication device of claim 8 , wherein the application list is configured by a user.

12. The mobile communication device of claim 8 , wherein the at least one processor is further configured to control the display to display a dividing line separating the first area and the second area based on the first input.

13. The mobile communication device of claim 8 , wherein each of the first input and the second input comprises one of a touch input that is generated by a user's finger or a touch input that is generated by an electronic pen.

14. The mobile communication device of claim 8 , wherein the first execution screen comprises at least one of a home window or an application window corresponding to an application selected by a user.

15. The method of claim 1 ,

wherein the mobile communication device stores a plurality of applications,

wherein the plurality of application comprises applications that can be used in a multi-screen environment and applications that cannot be used in the multi-screen environment, and

wherein the application list only includes applications that can be used in the multi-screen environment.

16. The mobile communication device of claim 8 , further comprising a memory configured to store a plurality of applications,

wherein the plurality of application comprises applications that can be used in a multi-screen environment and applications that cannot be used in the multi-screen environment, and

wherein the application list only includes applications that can be used in the multi-screen environment.

17. A mobile communication device comprising:

a display; and

at least one processor configured to:

control the display to display a first execution screen of a first application in a display area of the display in a full screen mode,

receive a first input of a first type dividing the first execution screen into a first area and a second area, the first input comprising a line drawn across the first execution screen, and the first area being larger or smaller than the second area,

split the display area of the display into a first window of a first predetermined size and a second window of a second predetermined size based on the first input,

control the display to display at least part of the first execution screen in the first window when the display area is split into the first window and the second window,

identify one or more applications executable in a multi-window mode from a plurality of applications installed in the mobile communication device,

control the display to display an application list including only the identified one or more applications in the second window when the display area is split into the first window and the second window,

receive a second input of a second type, different from the first type, for selecting an application from the application list,

control the display to display a second execution screen related to the selected application in the second window based on the second input while the at least part of the first execution screen is displayed in the first window, and

distinguish a type of input tool between the first input and the second input.

18. A method comprising:

controlling a display to display a first execution screen of a first application in a display area of the display in a full screen mode;

receiving a first input of a first type dividing the first execution screen into a first area and a second area, the first input comprising a line drawn across the first execution screen, and the first area being larger or smaller than the second area;

splitting the display area of the display into a first window of a first predetermined size and a second window of a second predetermined size based on the first input;

controlling the display to display at least part of the first execution screen in the first window when the display area is split into the first window and the second window;
