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 &amp; Title Case, <em>unless entire input has</em> no <em>lowercase</em>.
4. All words in AP style titles are capitalized except for certain short words, such as articles and short prepositions.
5. On Android, popup replaces context menus.
