Handheld electronic device with text disambiguation

摘要

A handheld electronic device with a reduced QWERTY keyboard and disambiguation software. The device outputs a default output and a number of variants. The output is based largely upon the likelihood that a user intended a particular output. Features of the device provide additional variants provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special key to enable a user to progressively select variants without changing hand position. The variant is highlighted and is displayed in a text component location on a display.
