- "Major mode for editing Texinfo files.
-
- 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] or
- `makeinfo'. 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 @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.
-
- Also, Texinfo mode provides functions for automatically creating or
- updating menus and node pointers. These functions
-
- * insert the `Next', `Previous' and `Up' pointers of a node,
- * insert or update the menu for a section, and
- * create a master menu for a Texinfo source file.
-
- Here are the functions:
-
- texinfo-update-node \\[texinfo-update-node]
- texinfo-every-node-update \\[texinfo-every-node-update]
- texinfo-sequential-node-update
-
- texinfo-make-menu \\[texinfo-make-menu]
- texinfo-all-menus-update \\[texinfo-all-menus-update]
- texinfo-master-menu
-
- texinfo-indent-menu-description (column &optional region-p)
-
- The `texinfo-column-for-description' variable specifies the column to
- which menu descriptions are indented.
-
- Passed an argument (a prefix argument, if interactive), the
- `texinfo-update-node' and `texinfo-make-menu' functions do their jobs
- in the region.
-
- To use the updating commands, you must structure your Texinfo file
- hierarchically, such that each `@node' line, with the exception of the
- Top node, is accompanied by some kind of section line, such as an
- `@chapter' or `@section' line.
-
- If the file has a `top' node, it must be called `top' or `Top' and
- be the first node in the file.
-
- Entering Texinfo mode calls the value of text-mode-hook, and then the
- value of texinfo-mode-hook."
