For document titles, use an initial capital letter for almost every word, except for words such as the, and, or, and for.
For all other titles or headings in a document, only capitalize the first letter of the first word and proper nouns. The following table shows examples of chapter and topic titles:

Exception for case-sensitive words
If the first word of a title is a case-sensitive lowercase word, rewrite the title. If you cannot rewrite the title, do not capitalize the first word.
