1. A data communications device, comprising: a receiver for receiving items of textual information contained in an incoming text message, a data processor operable in response to the received items of textual information to automatically extract textual information directly from said incoming text message, a plurality of keys each associated with a respective plurality of different text characters, the keys being operable by the user to produce an ambiguous key sequence corresponding to an item of textual information, a memory configuration to store different ones of said ambiguous key sequences and to associate with each thereof at least one item of said extracted textual information corresponding to the ambiguous key sequence, wherein the data processor is operable in response to the user actuating the keys to produce one of the ambiguous key sequences, to retrieve the extracted textual information associated therewith from the memory configuration to permit the user to disambiguate the produced key sequence, wherein the receiver is coupled to the memory configuration, and is operable to identify, based on knowledge of the association of text characters to the plurality of keys, an ambiguous key sequence corresponding to an item of the received textual information in said incoming text message, and to store the item of received textual information in the memory configuration such that it is associated with the identified ambiguous key sequence.
