@majorheading, @chapheading: Chapter-level Headings ¶The @majorheading and @chapheading commands produce
chapter-like headings in the body of a document.
However, neither command produces an entry in the table of contents, and neither command causes TeX to start a new page in a printed manual.
In TeX, a @majorheading command generates a larger vertical
whitespace before the heading than a @chapheading command but
is otherwise the same.
In other output formats, the @majorheading and @chapheading
commands produce a similar output to @chapter. The difference is
the lack of numbering and the lack of any association with nodes.
See @chapter: Chapter Structuring.
