A method and wireless terminal for presenting characters or images on a screen of a display provided in a folder pivotally mounted on the main body of a wireless terminal are provided. The method involves detecting an existence of a rotation allowable zone on the screen of the display upon turning the folder relative to the main body, detecting the existence of a pop-up window in the rotation allowable zone, if the rotation allowable zone exists, detecting the existence of particular keys provided in the folder, if the pop-up window exists in the rotation allowable zone, and turning the data presented in the rotation allowable zone and the data in the pop-up window, as well as rearranging the functions of the particular keys, to match the rotational direction of the folder, if the particular keys exist.
