1. A method of disambiguating an input into a handheld electronic device that comprises an input apparatus comprising a plurality of input members including a multiple-axis input device, an output apparatus, and a memory having stored therein a plurality of objects, the memory comprising a plurality of data sources each having a number of the objects stored therein, at least some of the input members each having a plurality of characters assigned thereto, the method comprising: detecting an input from the multiple-axis input device and, responsive thereto, moving an input focus to an input field; detecting an ambiguous input into the input field; determining that the input field is a special input field and, responsive thereto, identifying a predetermined data source from the plurality of data sources for analysis prior to analysis of at least one other data source to obtain a proposed disambiguation result, the predetermined data source being analyzed, if at all, without priority over the at least one other data source when the input field is not determined to be a special input field.
