Handheld electronic device with reduced keyboard and associated method of providing improved disambiguation with reduced degradation of device performance

摘要

An improved handheld electronic device having a reduced keyboard provides facilitated language entry by making available to a user certain words that a user may reasonably be expected to enter. Incoming data, such as the text of a message, can be scanned for proper nouns since such proper nouns might not already be stored in memory and might be expected to be entered by the user when forwarding or responding to the message. A proper noun can be identified on the basis that it begins with an upper case letter. The proper nouns can be stored in memory that may be a temporary dictionary.
