HANDHELD ELECTRONIC DEVICE AND ASSOCIATED METHOD PROVIDING ADVANCED TEXT EDITING FUNCTION IN A TEXT DISAMBIGUATION ENVIRONMENT

摘要

An improved handheld electronic device and associated method provide an advanced editing feature and an improved learning feature that are provided in a disambiguation environment. The advanced editing feature advantageously enables a new word that has been incorrectly disambiguated by a disambiguation routine to be readily by the user without requiring the incorrectly disambiguated word to be deleted and retyped. Rather, the advanced editing feature enables the incorrectly disambiguated characters to be replaced with opposite characters on the same keys, and such changes can be accomplished merely through the use of inputs to a track ball. The newly edited word can then be learned by a learning database. The improved learning function advantageously favors words that are learned using the advanced editing feature over words that have been learned in other fashions.
