Xiang has created an email that contains a number of acronyms and proper nouns. He would like to use Spell Checker quickly without modifying these entries or being notified for successive use of the same word or phrase. Which option should he choose in the Spell Checker?

Choose Ignore All. It skips the selected acronym or proper noun and prevents Spell Checker from flagging the same word again during the current check. Ignore Once would skip that occurrence only, so the same word could be flagged again later; Change options would modify the text.
