Notes

1. Undo (Ctrl+Z) can often be used to revert changes.
2. Keyboard Shortcuts can be set for case functions in the browser.
3. All CAPS and embedded CAP words are preserved in Sentence, Start & Title Case, unless entire input has no lowercase.
4. All words in AP style titles are capitalized except for certain short words, such as articles and short prepositions.
5. Lower Case can be used to force all letters to lower case (not preserving acronyms or brands).
