Choose the settings
For the recorded example, use these settings: Letter case: UPPERCASE.
UPPERCASE and lowercase convert letter casing directly. Title Case first lowercases the text, then capitalizes letters after whitespace. Sentence case also lowercases first, then capitalizes the beginning and letters following sentence-ending punctuation. These rules do not consult a dictionary of names, acronyms or editorial title styles.
