-
- It has these extra commands:
- \\{latexinfo-mode-map}
-
- These are files that are used as input for LaTeX to make printed manuals
- and also to be turned into Info files by \\[latexinfo-format-buffer].
- These files must be written in a very restricted and modified version
- of TeX input format.
-
- Editing commands are like text-mode except that the syntax table is
- set up so expression commands skip Latexinfo bracket groups. To see
- what the Info version of a region of the Latexinfo file will look like,
- use \\[latexinfo-format-region]. This command runs Info on the current region
- of the Latexinfo file and formats it properly.
-
- You can show the structure of a Latexinfo file with \\[latexinfo-show-structure].
- This command shows the structure of a Latexinfo file by listing the
- lines with the commands for \\node, \\chapter, \\section and the
- like. These lines are displayed in another window called the *Occur*
- window. In that window, you can position the cursor over one of the
- lines and use \\[occur-mode-goto-occurrence], to jump to the
- corresponding spot in the Latexinfo file.
-
- In addition, Latexinfo mode provides commands that insert various
- frequently used commands into the buffer. You can use these
- commands to save keystrokes. And you can insert balanced braces with
- \\[latexinfo-insert-braces] and later use the command \\[up-list] to
- move forward past the closing brace.
-
- Entering Latexinfo mode calls the value of text-mode-hook, and then the
- value of latexinfo-mode-hook."
