Can be processed to output

On the other hand, if it is determined in step 303 that the screen split mode is not present, the mobile terminal proceeds to step 309 to determine whether the menu selection mode. Here, the menu selection mode refers to a mode for selecting a program execution menu of the portable terminal by using the moving key, and processing the portable terminal to execute a menu existing at the position of the moving key.

If it is determined in step 309 that the menu selection mode, the portable terminal proceeds to step 311 to check the position of the movement key to check the menu present in the position of the movement key.

Thereafter, the portable terminal processes to execute a menu existing at the position of the mobile key.

On the other hand, if it is determined in step 309 that the menu selection mode is not, the mobile terminal proceeds to step 315 to determine whether the screen rotation mode. Herein, the screen rotation mode refers to a mode of rotating the output screen of the portable terminal at an angle such as 90 '180' according to the movement of the movement key.

If it is determined in step 315 that the screen rotation mode, the mobile terminal proceeds to step 317 and processes to rotate the output screen in the preset direction.

On the other hand, if it is determined in step 315 that the screen is not the rotation mode, the portable terminal proceeds to step 319 to enter the delete mode. Here, the delete mode refers to a mode that supports a delete function for deleting contents at once, such as a blackboard eraser, in a notepad or a picture editing program.

In step 321, the portable terminal enters the deletion mode. After confirming the movement section of the movement key by using the location of the current movement key, the portable terminal proceeds to step 323. Process to delete the picture drawn by using the contents or the picture editing program.

According to an exemplary embodiment of the present invention, the portable terminal divides or rotates the screen of the portable terminal using a navigation key or selects a menu, and the contents of the portable terminal are similar to a blackboard eraser in a notepad or a picture editing program. Although a method of deleting at one time has been described, the present invention can be applied to functions such as a game supported by the portable terminal (eg, batting of a baseball game, adjusting the shot size of a golf game), and adjusting the sound volume.
