A method for displaying a specific key pad in a terminal having a touch screen , the method comprising the steps of: detecting a touch gesture with respect to the touch screen ; determining whether the detected touch gesture is a zoom-in gesture comprising a touch gesture in which the user increases an interval between two fingers in a touched state on the touch screen; enlarging a displayed size of the specific key pad when the detected touch gesture is the zoom-in gesture; determining whether the detected touch gesture is a zoom-out gesture comprising a touch gesture in which the user reduces an interval between two fingers in a touched state on the touch screen ; reducing a displayed size of the specific key pad when the detected touch gesture is the zoom-out gesture; computing, while reducing the displayed size of the specific key pad, at least one of: a pinch of the zoom-out gesture, the pinch comprising a distance between two touched points; and a size of the reduced specific key pad; comparing the computed pinch with a preset pinch value and/or comparing the computed size with a preset size value; terminating the reduction of the displayed size of the specific key pad and displaying thumbnails, each thumbnail representing one of various key pads, when the computed pinch is less than the preset pinch value and/or when the computed size is less than the preset size value; and displaying , as the specific key pad, one of the key pads corresponding to a selected thumbnail when one of the displayed thumbnails is selected by a user. detecting a touch gesture with respect to the touch screen ; determining whether the detected touch gesture is a zoom-in gesture comprising a touch gesture in which the user increases an interval between two fingers in a touched state on the touch screen; enlarging a displayed size of the specific key pad when the detected touch gesture is the zoom-in gesture; determining whether the detected touch gesture is a zoom-out gesture comprising a touch gesture in which the user reduces an interval between two fingers in a touched state on the touch screen ; reducing a displayed size of the specific key pad when the detected touch gesture is the zoom-out gesture; computing, while reducing the displayed size of the specific key pad, at least one of: a pinch of the zoom-out gesture, the pinch comprising a distance between two touched points; and a size of the reduced specific key pad; comparing the computed pinch with a preset pinch value and/or comparing the computed size with a preset size value; terminating the reduction of the displayed size of the specific key pad and displaying thumbnails, each thumbnail representing one of various key pads, when the computed pinch is less than the preset pinch value and/or when the computed size is less than the preset size value; and displaying , as the specific key pad, one of the key pads corresponding to a selected thumbnail when one of the displayed thumbnails is selected by a user. a pinch of the zoom-out gesture, the pinch comprising a distance between two touched points; and a size of the reduced specific key pad; comparing the computed pinch with a preset pinch value and/or comparing the computed size with a preset size value; terminating the reduction of the displayed size of the specific key pad and displaying thumbnails, each thumbnail representing one of various key pads, when the computed pinch is less than the preset pinch value and/or when the computed size is less than the preset size value; and displaying , as the specific key pad, one of the key pads corresponding to a selected thumbnail when one of the displayed thumbnails is selected by a user. <EOS>
