A method of disambiguating an input into a handheld electronic device storing a plurality of objects includes a plurality of word objects is described. The method may include detecting an ambiguous input, outputting a number of first character permutations of the ambiguous input that each correspond to one of the word objects, and determining that the first character permutations are fewer in quantity than a predetermined number. The method may further include outputting a number of second character permutations of the ambiguous input that each correspond to an artificial variant.
