A method and apparatus for forming a sub-character on a touch-sensitive display, which comprises a touch-sensitive keyboard. In the method, a touching means is set to touch the surface of a key of said keyboard to form the main character of said key on a display device. Further, in the method, the touching location is moved along the surface of the keyboard to a distance from the initial location of the location of touch; an angle is calculated between said initial location and the termination location, which is located at the distance, relative to the formed straight and the coordination system, in which coordination system said initial location and termination location are located; the sub-character corresponding to the formed angle is selected; the selected sub-character is formed on the display apparatus. The sub-characters are indicated on the keys and show the sweeping direction. <IMAGE> |
