11. A handheld electronic device comprising: a processor apparatus including a memory having a plurality of objects stored therein, the plurality of objects including a plurality of language objects; an input apparatus including a plurality of input members, each of at least a portion of the input members of the plurality of input members having a plurality of linguistic elements assigned thereto; an output apparatus; the handheld electronic device being adapted to receive thereon a quantity of data including a number of language objects; the processor apparatus being adapted to identify from among the number of language objects in the received data a number of proper language objects, each proper language object having at least one upper case character, the processor apparatus being further adapted to identify at least some of the proper language objects as each comprising the same characters as one of the language objects stored in the memory and having at least one character of a different case than the same character of said one of the language objects; the processor apparatus being adapted to store in the memory said at least some of the proper language objects; the processor apparatus being adapted to detect an ambiguous input including a number of input member actuations of a number of the input members of the plurality of input members, each of at least a portion of the input members of the number of input members including a number of linguistic elements assigned thereto, at least one of the input members of the number of input members having a plurality of linguistic elements assigned thereto; the processor apparatus being adapted to identify in the memory a proper language object of the at least some of the proper language objects that corresponds with the ambiguous input; and the output apparatus being adapted to output at least a portion of the proper language object as a proposed disambiguation of the ambiguous input.
17. The handheld electronic device of claim 11 wherein the processor apparatus is adapted to compare the proper language objects of the number of proper language objects with the language objects of the plurality of language objects to identify the at least some of the proper language objects for storage in the memory.
