Notes:

1. Undo (Ctrl+Z) can often be used to revert changes.
2. Shortcuts can be set for case functions in the browser.
3. All CAPS and embedded CAP words are preserved in sentence, start & title case.
4. All words in AP style titles are capitalized except for certain short words, such as articles and short prepositions.
