- It has these extra commands:
- \\{texinfo-mode-map}
-
- These are files that are used as input for TeX to make printed manuals
- and also to be turned into Info files by \\[texinfo-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 Texinfo bracket groups. To see
- what the Info version of a region of the Texinfo file will look like,
- use \\[texinfo-format-region]. This command runs Info on the current region
- of the Texinfo file and formats it properly.
-
- You can show the structure of a Texinfo file with \\[texinfo-show-structure].
- This command shows the structure of a Texinfo file by listing the
- lines with the @-sign 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 Texinfo file.
-
- In addition, Texinfo mode provides commands that insert various
- frequently used @-sign commands into the buffer. You can use these
- commands to save keystrokes. And you can insert balanced braces with
- \\[texinfo-insert-braces] and later use the command \\[up-list] to
- move forward past the closing brace.
-
- Entering Texinfo mode calls the value of text-mode-hook, and then the
- value of texinfo-mode-hook."
