Abstract
A method of text entry into a device by activating keys of a keypad (16), where a key represents various characters. Input is delivered to a processor (30) corresponding to the keys activated. A dictionary (33) is searched for candidate combinations of characters corresponding to the keys activated. The candidate combinations are rank ordered, for example using language model data and feedback (14, 38) is provided to a user indicating at least a highest rank ordered candidate combination.
