Method and device for implementing a function
First Claim
1. A method of performing a sub-function on a touch-sensitive surface, the method comprising the steps of showing at least one key on a touch-sensitive surface;
- showing on said key at least one character indicating a main function at a given first location of said key;
showing on said key at least one character indicating a sub-function at a given second location of said key; and
detecting the touch of said key on the touch-sensitive surface, wherein the method further comprising the steps of detecting the movement of the touch along the touch-sensitive surface to a distance from the initial location of the location of touch in a given direction; and
implementing said sub-function as a response to the detection of said movement of touch.

Abstract
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.
