+@top AUC @TeX{}
+AUC @TeX{} is an integrated environment for editing La@TeX{} and
+@TeX{} files.@refill
+This file documents AUC @TeX{} version 9.7.
+Although AUC @TeX{} contains a large number of features, there are no
+reasons to despair.  You can continue to write @TeX{} and La@TeX{}
+documents the way you are used to, and only start using the multiple
+features in small steps.  AUC @TeX{} is not monolithic, each feature
+described in this manual is useful by itself, but together they provide
+an environment where you will make very few LaTeX errors, and makes it
+easy to find the errors that may slip through anyway.
+If you want to make AUC TeX aware of style files and multi-file
+documents right away, insert the following in your @file{.emacs} file.
+@lisp
+(setq TeX-auto-save t)
+(setq TeX-parse-self t)
+(setq-default TeX-master nil)

+important points.  Corrections or perhaps rewrites of sections
+are VERY WELCOME.@refill

+simply insert templates for often used @TeX{} and/or La@TeX{}
+constructs, like font changes, handling of environments, etc.

+@cindex Dollars
+@cindex Math mode delimiters
+@cindex Matching dollar signs
+@cindex Display math mode
+In @TeX{} literal double quotes @samp{"like this"} are seldom used,
+instead two single quotes are used @samp{``like this''}.  To help you
+insert these efficiently, AUC @TeX{} allows you to continue to press
+@kbd{"} to insert two single quotes.  To get a literal double quote,
+press @kbd{"} twice.
+@deffn Command TeX-insert-quote @var{count}
+@kindex "
+(@kbd{"}) Insert the appropriate quote marks for TeX.
+Inserts the value of @code{TeX-open-quote} (normally @samp{``}) or
+@code{TeX-close-quote} (normally @samp{''}) depending on the context.
+With prefix argument, always inserts @samp{"} characters.@refill
+@end deffn
+@defopt TeX-open-quote
+String inserted by typing @kbd{"} to open a quotation.
+@end defopt
+@defopt TeX-close-quote
+String inserted by typing @kbd{"} to open a quotation.
+@end defopt
+If you include the style file @file{german} @code{TeX-open-quote} and
+@code{TeX-close-quote} will both be set to @samp{"}.
+In AUC @TeX{}, dollar signs should match like they do in @TeX{}.  This
+has been partially implemented, we assume dollar signs always match
+within a paragraph.  The first @samp{$} you insert in a paragraph will
+do nothing special.  The second @samp{$} will match the first.  This
+will be indicated by moving the cursor temporarily over the first dollar
+sign.  If you enter a dollar sign that matches a double dollar sign
+@samp{$$} AUC @TeX{} will automatically insert two dollar signs.  If you
+enter a second dollar sign that matches a single dollar sign, the single
+dollar sign will automatically be converted to a double dollar sign.
+@deffn Command TeX-insert-dollar @var{arg}
+@kindex $
+(@kbd{$}) Insert dollar sign.
+Show matching dollar sign if this dollar sign end the @TeX{} math mode.
+Ensure double dollar signs match up correctly by inserting extra
+dollar signs when needed.
+With optional @var{arg}, insert that many dollar signs.
+@end deffn
+To avoid unbalanced braces, it is useful to insert them pairwise.  You
+can do this by typing @kbd{C-c @{}.
+@deffn Command TeX-insert-braces
+@kindex C-c @{
+(@kbd{C-c @{}) Make a pair of braces and position the cursor
+to type inside of them.

+@cindex Specifying a font
+Perhaps the most used keyboard commands of AUC @TeX{} are the short-cuts
+available for easy insertion of font changing macros.  They all put the
+font change inside a @TeX{} group, a practice that help preventing
+subtle errors.  The most significant advantage of using these command
+instead of typing it in yourself, is that the braces will always match
+correctly.
+If you give an argument (that is, type @kbd{C-u}) to the font command,
+the innermost font will be replaced, i.e. the font in the @TeX{} group
+around point will be changed.  The following table shows the available
+commands, with @code{@point{}} indicating the position where the text

+A large apparatus is available that supports insertions of environments,

+@samp{\documentstyle} command, and consulting a precompiled list of
+environments available in a large number of styles.
+You insert an environment with @kbd{C-c C-e}, and select an environment
+type.  Depending on the environment, AUC @TeX{} may ask more questions
+about the optional parts of the selected environment type.  With
+@kbd{C-u C-c C-e} you will change the current environment.
+@deffn Command LaTeX-environment @var{arg}

+to insert.  At this prompt, you may press @key{TAB} or @key{SPC} to
+complete a partially written name, and/or to get a list of available
+environments.  After selection of a specific environment AUC @TeX{} may
+prompt you for further specifications.

+@code{LaTeX-complete-symbol} makes it easier to type and remember the
+names of long La@TeX{} macros.
+In order to use @code{TeX-complete-symbol}, you should write a backslash
+and the start of the macro.  Typing @kbd{M-@key{TAB}} will now
+complete as much of the macro, as it unambiguously can.  For example, if
+you type `@samp{\renewc}' and then `@kbd{M-@key{TAB}}, it will expand
+to `@samp{\renewcommand}'.
+@deffn Command TeX-complete-symbol
+@kindex M-@key{TAB}
+(@kbd{M-@key{TAB}})  Complete @TeX{} symbol before point.
+@end deffn
+A more direct way to insert a macro is with @code{TeX-insert-macro},
+bound to @kbd{C-c C-m}.  It has the advantage over completion that it
+knows about the argument of most standard La@TeX{} macros, and will
+prompt for them.  It also knows about the type of the arguments, so it
+will for example give completion for the argument to @samp{\include}.
+Some examples are listed below.
+@deffn Command TeX-insert-macro
+@kindex C-c C-m
+(@kbd{C-c C-m}) Prompt (with completion) for the name of a @TeX{} macro,
+and if AUC @TeX{} knows the macro, prompt for each argument.
+@end deffn
+As a default selection, AUC @TeX{} will suggest the macro last inserted
+or, as the first choice the value of the variable
+@code{TeX-default-macro}.
+@defopt TeX-default-macro
+Default macro to insert when invoking @code{TeX-insert-macro} first time.
+@end defopt
+A faster alternative is to bind the function @code{TeX-electric-macro}
+to @samp{\}.  This can be done by setting the variable @code{TeX-electric-escape}
+@defopt TeX-electric-escape
+If this is non-nil when AUC @TeX{} is loaded, the @TeX{} escape
+character @samp{\} will be bound to @code{TeX-electric-macro}
+@end defopt
+The difference between @code{TeX-insert-macro} and
+@code{TeX-electric-macro} is that space will complete and exit from the
+minibuffer in @code{TeX-electric-macro}.  Use @key{TAB} if you merely
+want to complete.
+@deffn Command TeX-electric-macro
+Prompt (with completion) for the name of a @TeX{} macro,
+and if AUC @TeX{} knows the macro, prompt for each argument.
+Space will complete and exit.
+@end deffn
+By default AUC @TeX{} will put an empty set braces @samp{@{@}} after a
+macro with no arguments to stop it from eating the next whitespace.
+This can be stopped by entering @code{LaTeX-math-mode},
+@pxref{Mathematics}, or by setting @code{TeX-insert-braces} to nil
+@defopt TeX-insert-braces
+If non-nil, append a empty pair of braces after inserting a macro.
+@end defopt
+Completions work because AUC @TeX{} can analyze @TeX{} files, and store
+symbols in emacs lisp files for later retrieval.  @xref{Automatic}, for
+more information.

+AUC @TeX{} will also make completion for many macro arguments, for
+example existing labels when you enter a @samp{\ref} macro with
+@code{TeX-insert-macro} or @code{TeX-electric-macro}, and Bib@TeX{}
+entries when you enter a @samp{\cite} macro.  For this kind of
+completion to work, parsing must be enabled as described in
+@pxref{Parsing Files}.  For @samp{\cite} you must also make sure that
+the Bib@TeX{} files have been saved at least once after you enabled
+automatic parsing on save, and that the basename of the Bib@TeX{} file
+does not conflict with the basename of one of @TeX{} files.

+It is often necessary to comment out temporarily a region of @TeX{} or
+La@TeX{} code.  This can be done with the commands @kbd{C-c ;} and
+@kbd{C-c %}.  @kbd{C-c ;} will comment out all lines in the current
+region, while @kbd{C-c %} will comment out the current paragraph.  To
+uncomment, simply type @kbd{C-u - C-c ;} to uncomment all lines in the
+region, or @kbd{C-u - C-c %} uncomment all comment lines around point.
+By default, these commands will insert or remove a single @samp{%}.  To
+insert more than one, give an argument. @kbd{C-u 5 C-c %} will add five
+@samp{%} to each line, while @kbd{C-u - 5 C-c %} will remove up to 5
+@samp{%} from each line.

+@cindex Reindenting
+AUC @TeX{} contains very advanced handling of indentation and
+reformatting of the La@TeX{} source.  If you have already tried AUC
+@TeX{} with @code{auto-fill-mode} enabled, you may have noted that the
+source is automatically indented and formatted as you write it.  More
+over, AUC @TeX{} is able to format sections of text on demand.
+It is important to realize, that AUC @TeX{} comes with `formatting' in
+two fashions.  Either letting @TeX{} format the file, or letting AUC
+@TeX{} make the ASCII document look better.
+Indentation is done by La@TeX{} environments and by @TeX{} groups, that
+is the body of an environment is indented by the value of
+@code{LaTeX-indent-level} (default 2).  Also, items of an `itemize-like'
+environment are indented by the value of @code{LaTeX-item-indent},
+default @minus{}2.  This indentation makes it easier to see the
+structure of the document, and to catch errors such as a missing close
+brace.  Thus, the indentation is done for precisely the same reasons
+that you would indent ordinary computer programs.
+@vindex LaTeX-indent-level
+@vindex LaTeX-item-indent
+The following is a short sample of an itemize environment indented by
+AUC @TeX{}.  If more environment are nested, they are indented
+`accumulated' just like most programming languages usually are seen
+indented in nested constructs.
+@example
+\begin@{itemize@}
+\item Insertion of templates for logical-structural compositions such as
+environments and sections.
+\item Hot-keys for easy access to certain often used constructs, e.g.,
+font changes, accented letters, and mathematical symbols.
+\item Running application programs (such as \TeX), and then parsing
+the output so that errors in the document may be located
+easily.
+\item Support for multi-file documents.
+\item Online help for \AllTeX\ error messages.
+\item Outlining\Dash i.e., manipulating the document as a composition
+of nested/sequential logical constructs.
+\item Instant formatting and indentation of the \ascii-document in
+order to make it easier to read.
+\item `Completion' (and thereby spell-checking) of partially written
+control sequences.
+\end@{itemize@}

+You can format and indent single lines, paragraphs, environments, or
+sections.
+@table @kbd

+AUC @TeX{} keeps track of macros, environments, labels, and style

+AUC @TeX{} depends heavily on being able to extract information from the
+buffers by parsing them.  Since parsing the buffer can be somewhat slow,
+the parsing is initially disabled.  You are encouraged to enable them by
+adding the following lines to your @file{.emacs} file.
+@lisp
+(setq TeX-parse-self t) ; Enable parse on load.
+(setq TeX-auto-save t) ; Enable parse on save.
+@end lisp
+The later command will make AUC @TeX{} store the parsed information in
+an @file{auto} subdirectory in the directory each time the @TeX{} files
+are stored, @pxref{Automatic Local}.  If AUC @TeX{} finds the pre-parsed
+information when loading a file, it will not need to reparse the buffer.
+The information in the @file{auto} directory is also useful for
+multifile documents @pxref{Multifile}, since it allows each file to
+access the parsed information from all the other files in the document.
+This is done by first reading the information from the master file, and
+then recursively the information from each file stored in the master
+file.@refill
+The variables can also be done on a per file basis, by changing the file
+local variables.
+@example
+% Local Variables:
+% TeX-parse-self: t
+% TeX-auto-save: t
+% End:
+@end example
+Even when you have disabled the automatic parsing, you can force the
+generation of style information by pressing @kbd{C-c C-n}.  This is
+often the best choice, as you will be able to decide when it is
+necessary to reparse the file.
+@defopt TeX-parse-self
+Parse file after loading it if no style hook is found for it.
+@end defopt
+@defopt TeX-auto-save
+Automatically save style information when saving the buffer.
+@end defopt
+@deffn Command TeX-normal-mode @var{arg}
+@kindex C-c C-n
+(@kbd{C-c C-n}) Remove all information about this buffer, and apply the
+style hooks again.  Save buffer first including style information.  With
+optional argument, also reload the style hooks.
+@end deffn
+When AUC TeX saves your buffer, it will by default convert all tabs in
+your buffer into spaces.  To disable this behaviour, insert the
+following in your @file{.emacs} file.
+@lisp
+(setq TeX-auto-untabify nil)
+@end lisp
+@defopt TeX-auto-untabify
+Automatically remove all tabs from a file before saving it.
+@end defopt
+Instead of disabling the parsing entirely, you can also speed it
+significantly up by limiting the information it will search for (and
+store) when parsing the buffer.  You can do this by setting the default
+values for the buffer local variables @code{TeX-auto-regexp-list} and
+@code{TeX-auto-parse-length} in your @file{.emacs} file.
+@lisp
+;; Only parse \documentstyle information.
+(setq-default TeX-auto-regexp-list 'LaTeX-auto-minimal-regexp-list)
+;; The documentstyle command is usually near the beginning.
+(setq-default TeX-auto-parse-length 2000)
+@end lisp
+This example will speed the parsing up significantly, but AUC @TeX{}
+will no longer be able to provide completion for labels, macros,
+environments, or bibitems specified in the document, nor will it know
+what files belong to the document.
+These variables can also be specified on a per file basis, by changing
+the file local variables.
+@example
+% Local Variables:
+% TeX-auto-regexp-list: TeX-auto-full-regexp-list
+% TeX-auto-parse-length: 999999

+Since AUC @TeX{} is so highly customizable, it makes sense that it is able
+to customize itself.  The automatic customization consists of scanning
+@TeX{} files and extracting symbols, environments, and things like that.
+The automatic customization is done on three different levels.  The
+global level is the level shared by all users at your site, and consists
+of scanning the standard @TeX{} style files, and any extra styles added
+locally for all users on the site.  The private level deals with those
+style files you have written for your own use, and use in different
+documents.  You may have a @file{~/lib/TeX/} directory where you store
+useful style files for your own use.  The local level is for a specific
+directory, and deals with writing customization for the files for your
+normal @TeX{} documents.
+If compared with the environment variable @code{TEXINPUTS}, the
+global level corresponds to the directories built into @TeX{}.  The
+private level corresponds to the directories you add yourself, except for
+@file{.}, which is the local level.

+@defun TeX-add-symbols @var{symbol} @dots{}
+Add each @var{symbol} to the list of known symbols.
+@end defun
+Each argument to @code{TeX-add-symbols} is a list describing one symbol.
+The head of the list is the name of the symbol, the remaining elements
+describe each argument.
+If there are no additional elements, the symbol will be inserted with
+point inside braces.  Otherwise, each argument of this function should
+match an argument of the @TeX{} macro.  What is done depends on the argument
+type.
+If a macro is defined multiple times, AUC @TeX{} will chose the one with
+the longest definition (i.e. the one with the most arguments).
+Thus, to overwrite
+@example
+'("tref" 1) ; one argument
+@end example
+you can specify
+@example
+'("tref" TeX-arg-label ignore) ; two arguments
+@end example
+@code{ignore} is a function that does not do anything, so when you
+insert a @samp{tref} you will be prompted for a label and no more.

+@item number
+Insert that many braces, leave point inside the first.
+@item nil
+Insert empty braces.
+@item t
+Insert empty braces, leave point between the braces.
+@item other symbols
+Call the symbol as a function.  You can define your
+own hook, or use one of the predefined argument hooks.
+@item list
+If the car is a string, insert it as a prompt and the next
+element as initial input.  Otherwise, call the car of the list with
+the remaining elements as arguments.
+@item vector
+Optional argument.  If it has more than one element, parse it
+as a list, otherwise parse the only element as above.  Use square
+brackets instead of curly braces, and is not inserted on empty user
+input.
+@end table
+A lot of argument hooks have already been defined.  The first argument to

+any.  Typically the next argument is used to overwrite the default
+prompt.

+@cindex Defining environments in style hooks
+Adding support for environments is very much like adding support for
+@TeX{} macros, except that each environment normally only takes one
+argument, an environment hook.  The example is again a short version of
+@file{latex.el}.
+@lisp
+(TeX-add-style-hook "latex"
+(function
+(lambda ()
+(LaTeX-add-environments
+'("document" LaTeX-env-document)
+'("enumerate" LaTeX-env-item)
+'("itemize" LaTeX-env-item)
+'("list" LaTeX-env-list)))))
+@end lisp
+@findex LaTeX-env-item
+The only hook that is generally useful is @code{LaTeX-env-item}, which is
+used for environments that contain items.  It is completely up to the
+environment hook to insert the environment, but the function
+@code{LaTeX-insert-environment} may be of some help.  The hook will be
+called with the name of the environment as its first argument, and extra
+arguments can be provided by adding them to a list after the hook.
+For simple environments with arguments, for example defined with
+@samp{\newenvironment}, you can make AUC @TeX{} prompt for the arguments
+by giving the prompt strings in the call to
+@code{LaTeX-add-environments}.  For example, if you have defined a
+@code{loop} environment with the three arguments @var{from}, @var{to},
+and @var{step}, you can add support for them in a style file.
+@example
+%% loop.sty
+\newenvironment@{loop@}[3]@{...@}@{...@}
+@end example
+@lisp
+;; loop.el
+(TeX-add-style-hook "loop"
+(function
+(lambda ()
+(LaTeX-add-environments
+'("loop" "From" "To" "Step")))))
+@end lisp
+If an environment is defined multiple times, AUC @TeX{} will chose the
+one with the longest definition.  Thus, if you have an enumerate style
+file, and want it to replace the standard La@TeX{} enumerate hook above,
+you could define an @file{enumerate.el} file as follows, and place it in
+the appropriate style directory.
+@lisp
+(TeX-add-style-hook "latex"
+(function
+(lambda ()
+(LaTeX-add-environments
+'("enumerate" LaTeX-env-enumerate foo)))))
+(defun LaTeX-env-enumerate (environment &optional ignore) ...)
+@end lisp
+The symbol @code{foo} will be passed to @code{LaTeX-env-enumerate} as
+the second argument, but since we only added it to overwrite the
+definition in @file{latex.el} it is just ignored.
+@defun LaTeX-add-environments @var{env} @dots{}
+Add each @var{env} to list of loaded environments.
+@end defun
+@defun LaTeX-insert-environment @var{env} [ @var{extra} ]
+Insert environment of type @var{env}, with optional argument @var{extra}.

+@section Automatic Extraction of New Things
+@cindex Parsing new macros
+@cindex @file{macro.tex}
+@cindex @file{macro.el}
+@cindex Changing the parser
+The automatic @TeX{} information extractor works by searching for
+regular expressions in the @TeX{} files, and storing the matched
+information.  You can add support for new constructs to the parser,
+something that is needed when you add new commands to define symbols.
+For example, in the file @file{macro.tex} I define the following macro.
+@example
+\newcommand@{\newmacro@}[5]@{%
+\def#1@{#3\index@{#4@@#5~cite@{#4@}@}\nocite@{#4@}@}%
+\def#2@{#5\index@{#4@@#5~cite@{#4@}@}\nocite@{#4@}@}%
+@}
+@end example
+AUC @TeX{} will automatically figure out that @samp{newmacro} is a macro
+that takes five arguments.  However, it is not smart enough to
+automatically see that each time we use the macro, two new macros are
+defined.  We can specify this information in a style hook file.
+@lisp
+;;; macro.el - Special code for my own macro file.
+;;; Code:
+(defvar TeX-newmacro-regexp
+'("\\\\newmacro@{\\\\\\([a-zA-Z]+\\)@}@{\\\\\\([a-zA-Z]+\\)@}"
+(1 2) TeX-auto-multi)
+"Matches \newmacro definitions.")
+(defvar TeX-auto-multi nil
+"Temporary for parsing \\newmacro definitions.")
+(defun TeX-macro-cleanup ()
+;; Move symbols from `TeX-auto-multi' to `TeX-auto-symbol'.
+(mapcar (function (lambda (list)
+(mapcar (function (lambda (symbol)
+(setq TeX-auto-symbol
+(cons symbol TeX-auto-symbol))))
+list)))
+TeX-auto-multi))
+(defun TeX-macro-prepare ()
+;; Clear `Tex-auto-multi' before use.
+(setq TeX-auto-multi nil))
+(add-hook 'TeX-auto-prepare-hook 'TeX-macro-prepare)

+(TeX-auto-add-regexp TeX-newmacro-regexp)
+(TeX-add-symbols '("newmacro"
+TeX-arg-macro
+(TeX-arg-macro "Capitalized macro: \\")
+t
+"BibTeX entry: "
+nil)))))
+;;; macro.el ends here
+@end lisp
+When this file is first loaded, it adds a new entry to
+@code{TeX-newmacro-regexp}, and defines a function to be called before
+the parsing starts, and one to be called after the parsing is done.  It
+also declares a variable to contain the data collected during parsing.
+Finally, it adds a style hook which describes the @samp{newmacro} macro,
+as we have seen it before.
+So the general strategy is: Add a new entry to @code{TeX-newmacro-regexp}.
+Declare a variable to contain intermediate data during parsing.  Add hook
+to be called before and after parsing.  In this case, the hook before
+parsing just initializes the variable, and the hook after parsing
+collects the data from the variable, and adds them to the list of symbols
+found.
+@defvar TeX-auto-regexp-list
+List of regular expressions matching @TeX{} macro definitions.
+The list has the following format ((REGEXP MATCH TABLE) @dots{}), that
+is, each entry is a list with three elements.
+REGEXP.  Regular expression matching the macro we want to parse.
+MATCH.  A number or list of numbers, each representing one
+parenthesized subexpression matched by REGEXP.
+TABLE.  The symbol table to store the data.  This can be a function, in
+which case the function is called with the argument MATCH.  Use
+@code{TeX-match-buffer} to get match data.  If it is not a function, it
+is presumed to be the name of a variable containing a list of match
+data.  The matched data (a string if MATCH is a number, a list of
+strings if MATCH is a list of numbers) is put in front of the table.

+@kbd{C-c C-q C-e} doesn't work properly on nested itemize environments.
+Reported by  "Robert B. Love"  <rlove@@raptor.rmNUG.ORG>.
+@item
+One suggestion for AUC-TeX: I think that the font command C-c C-f C-r,
+which produces \textrm@{@} in a LaTeX file, should instead produce
+either \textrm@{@} or \mathrm@{@}, depending on whether one is in math
+mode or not. --- John Palmieri <palmieri@@math.mit.edu>
+@item
+A way to add and overwrite math mode entries in style files, and to
+decide where they should be.  Suggested by Remo Badii <Remo.Badii@@psi.ch>.
+@item
+Create template for (first) line of tabular environment.
+@item
+I think prompting for the master is the intended behaviour.  It
+corresponds to a `shared' value for TeX-master.
+There should probably be a `none' value which wouldn't query for the
+master, but instead disable all features that relies on TeX-master.
+This default value for TeX-master could then be controled with mapping
+based on the extension.
+@item
+@kbd{C-c '} should alway stay in the current window, also when it find a
+new file.
+@item
+@code{LaTeX-fill-environment} does not indent the closing @samp{\end}.

+Rewrite @file{ltx-help.el} and put it in @file{latex.el}.  Fix also:
+@example
+From: Denby Wong <DnB@@slip224.qlink.QueensU.CA>
+1) change documentation regarding where to get the
+latest version (at CTAN at pip.shsu.edu for me)
+under info/latex2e-help-texinfo/
+2) change or provide choice over which version to
+use.  There are three references to the info
+node "(latex)" in the file which should be
+"(latex2e)"  for the new file.
+From: Piet van Oostrum <piet@@cs.ruu.nl>
+One of the annoying things of latex-help is that if you ask for \LARGE, you
+get \large if you have case-fold-search=t. This is really info's problem as
+it doesn't reset it for a search of the node, but it would be easy to stick
+a (let (case-fold-search) in latex-help.

+It should be possible to insert a default preamble containing
