The invention proposes a method to retrieve a character corresponding to previous pressing of a key. Here the key is from a keypad of an electronic device like a mobile phone. As the number of physical keys are limited in the electronic device, each key (K1 to K12) is associated with a set of characters. Pressing of same key repetitively within a predefined time, generates different characters, in a predefined sequence an in a cyclic manner. If the user by mistake does not stop after required number of pressings and continues, a different character is generated which may not be what user intended to enter. The invention provides a method wherein a pressing of a soft key on the key pad retrieves the previously generated character. Thus the user does not have to restart the cycle to enter the intended character. |
