Title case isn't one rule. Style guides disagree about which small words stay lowercase: AP lowercases prepositions of three letters or fewer, Chicago lowercases every preposition, and APA capitalizes anything of four letters or more. Words that differ between styles are underlined, so you can see where they disagree.

Acronyms like NASA and U.S. and names like iPhone stay as you typed them. A line typed entirely in capitals is recased, since acronyms can't be told apart from shouting.
