Handheld electronic device with text disambiguation employing advanced editing feature

An electronic device comprising:

• a processor unit including a processor, an input apparatus, an output apparatus, and a memory having a plurality of objects and a routine stored therein;
• the plurality of objects including a plurality of language objects;
• the input apparatus including a plurality of keys;
• and
• the routine being adapted to cause the processor to perform operations comprising:
• detecting a text input comprising a number of key selections,
• causing the output of a default interpretation of the text input comprising an initial portion and a terminal portion adjacent one another, the initial portion including a number of initial linguistic elements at an initial end of the default interpretation, the terminal portion including a number of terminal linguistic elements at a terminal end of the default interpretation,
• detecting a deletion input with respect to the terminal portion of the default interpretation,
• detecting a selection of another key that successively follows the deletion input,
• determining that the another key is the same key as that which provided a terminal linguistic element that was adjacent the initial portion before deletion,
• responsive to the determining, cause the output of, as a replacement default interpretation, the initial portion and a replacement linguistic element assigned to the another key that differs from the terminal linguistic element that was adjacent the initial portion before deletion,
• detecting a selection of an additional key, and
• causing the output of, as a replacement of the replacement default interpretation, the initial portion, the replacement linguistic element, and an additional linguistic element, and further causing the output of a variant interpretation comprising the initial portion, the replacement linguistic element, and an alternative linguistic element different than the additional linguistic element.

A method of enabling input on an electronic device that comprises an input apparatus, a processor, and a memory having stored therein a number of language objects and a disambiguation routine, the input apparatus comprising a plurality of input keys, the method comprising:

• detecting a text input comprising a number of selections of a number of input keys, at least one of the selections being an ambiguous input;
• performing a disambiguation operation of the text input to generate a number of disambiguated interpretations of the text input that each comprises a character for each ambiguous input;
• outputting one of the number of disambiguated interpretations as a default output;
• detecting a deletion input with respect to one of the characters of the default output, the one of the characters being assigned to a particular input key of the text input;
• detecting a reselection of the particular input key successively following the deletion input, the reselection being a selection of the particular input key;
• responsive to the detecting of the deletion input and the detecting of the reselection, outputting as a replacement default output, a disambiguated interpretation having the one of the characters deleted by the deletion input replaced by a character assigned to the particular input key other than the one of the characters deleted by the deletion input;
• detecting a selection of an additional key;
• and
• outputting, as a replacement of the replacement default interpretation, the initial portion, the replacement linguistic element, and an additional linguistic element, and further outputting a variant interpretation comprising the initial portion, the replacement linguistic element, and an alternative linguistic element different than the additional linguistic element.
