In the Spelling and Grammar dialog box, which option should a user choose when a special term, like a proper noun or an abbreviation, should not be flagged as misspelled again?

Choose “Add to Dictionary” to save the special term in the program’s dictionary. The spelling checker will then recognize it and won’t flag it as misspelled in the future. “Ignore Once” and “Ignore All” only skip the warning without adding the term to the dictionary.
