Abstract
A system to be used to add non-listed characters (i.e., characters not listed in character key-in methods) to the vocabulary banks of character-key-in methods used in hand-held mobile communication devices is disclosed. Users of a mobile communication device can select a character or characters which are built in the system but not indexed by a certain character-key-in method (that is, the characters cannot be keyed in with that character-key-in method), index the aforesaid characters, using the indexing system/method of the character-key-in method, and then add them to the key-in method's character-indexing system so that subsequent users of the mobile communication device can use said character-key-in method to key in said (originally non-indexed/listed) characters.
