You can show the section structure of a Texinfo file by using the
C-c C-s command (texinfo-show-structure). This command
shows the section structure of a Texinfo file by listing the lines
that begin with the @-commands for @chapter,
@section, and the like. It constructs what amounts
to a table of contents. These lines are displayed in another buffer
called the `*Occur*' buffer. In that buffer, you can position
the cursor over one of the lines and use the C-c C-c command
(occur-mode-goto-occurrence), to jump to the corresponding spot
in the Texinfo file.
@chapter, @section, and such lines of a
Texinfo file.
If you call texinfo-show-structure with a prefix argument by
typing C-u C-c C-s, it will list not only those lines with the
@-commands for @chapter, @section, and the like,
but also the @node lines. (This is how the
texinfo-show-structure command worked without an argument in
the first version of Texinfo. It was changed because @node
lines clutter up the `*Occur*' buffer and are usually not
needed.) You can use texinfo-show-structure with a prefix
argument to check whether the `Next', `Previous', and `Up' pointers of
an @node line are correct.
Often, when you are working on a manual, you will be interested only
in the structure of the current chapter. In this case, you can mark
off the region of the buffer that you are interested in by using the
C-x n n (narrow-to-region) command and
texinfo-show-structure will work on only that region. To see
the whole buffer again, use C-x n w (widen).
(See section `Narrowing' in The GNU Emacs Manual, for more
information about the narrowing commands.)
In addition to providing the texinfo-show-structure command,
Texinfo mode sets the value of the page delimiter variable to match
the chapter-level @-commands. This enables you to use the C-x
] (forward-page) and C-x [ (backward-page)
commands to move forward and backward by chapter, and to use the
C-x p (narrow-to-page) command to narrow to a chapter.
See section `Pages' in The GNU Emacs Manual, for more information
about the page commands.
