    &ls; attempts to provide a comprehensive set of tools to
    view, edit and compile LaTeX documents in Vim. Together, they
    provide tools starting from macros to speed up editing LaTeX
    documents to functions for forward searching .dvi documents.
    &ls; has been possible because of the contributions of many
    people. Please see <link

    people who have helped.

  <title>Installation and recommended Settings</title>
  <para>
   If you are reading this, it most probably means that you have already
   installed &ls; and the help files. If this is not the case, follow the
   detailed instructions on <ulink
    url="http://vim-latex.sourceforge.net/index.php?subject=download">&ls;'s
    download page</ulink>.
  </para>
  <para>
   Make sure that you create a few necessary settings in your
   <literal>~/.vimrc.</literal>
   <programlisting>
" REQUIRED. This makes vim invoke &ls; when you open a tex file.
filetype plugin on

" IMPORTANT: win32 users will need to have 'shellslash' set so that latex
" can be called correctly.
set shellslash

" OPTIONAL: This enables automatic indentation as you type.
filetype indent on

" OPTIONAL: Starting with Vim 7, the filetype of empty .tex files defaults to
" 'plaintex' instead of 'tex', which results in vim-latex not being loaded.
" The following changes the default filetype back to 'tex':
let g:tex_flavor='latex'
</programlisting>
  </para>
  <para>
   In addition, the following settings could go in your ~/.vim/ftplugin/tex.vim
   file:
   <programlisting>" this is mostly a matter of taste. but LaTeX looks good with just a bit
" of indentation.
set sw=2
" TIP: if you write your \label's as \label{fig:something}, then if you
" type in \ref{fig: and press &lt;C-n&gt; you will automatically cycle through
" all the figure labels. Very useful!
set iskeyword+=:
</programlisting>
  </para>
  <para>
    In the unlikely case that &ls; is installed, but you do not want to use it
    (e.g., if it is installed system-wide and you use some other package to deal
    with tex files),
    you can suppress the loading of &ls; by setting
    <programlisting>let b:suppress_latex_suite = 1</programlisting>
    in your ~/.vim/ftplugin/tex.vim.
  </para>

 <section id="latex-suite-templates">
  <title>Inserting Templates</title>
  <para>
   This functionality is available via the <literal>TeX-Suite &gt;
    Templates</literal> menu.
   This module provides a way to insert custom templates at the beginning of the
   current file.
  </para>
  <para>
   When &ls; first starts up, it scans the
   <link linkend="Tex_CustomTemplateDirectory">template directory</link>
   and creates menu items based on the files found there. When
   you select a template from this menu, the file will be read in above
   the first line of the current file.
  </para>
  <para>
   A template file can utilize placeholders for initializing the cursor
   position when the template is read in and subsequent movement. In
   addition, template files can contain dynamic elements such as the
   time of creation of a file etc, by using vim expressions.
  </para>
  <para>
   You can place your own templates in the
   <link linkend="Tex_CustomTemplateDirectory">template directory</link>
   in
   order for them to be available via the menu.
  </para>
  <note>
   <para>
    Templates are also accessible for non-gui users with the command
    |<literal>:TTemplate</literal>|. The argument should be name of
    the corresponding template file.  If the command is called
    without arguments (preferred usage), then a list of available
    templates is displayed and the user is asked to choose one of
    them.
   </para>

 <section id="latex-macros">
  <title>&ls; Macros</title>
  <para>
   &ls; ships with a very comprehensive set of insert mode and
   |visual-mode| mappings and menu items to typeset most of the LaTeX
   elements.
  </para>
  <note>
   <para>
    These mappings are are not standard mappings in the sense that
    only the last character is mapped. See plugin/imaps.vim for
    further documentation. For example, in the case of the mapping
    <literal>EFI</literal> provided by &ls; you can press the characters
    '<literal>E</literal>', '<literal>F</literal>' and '<literal>I</literal>'
    as slowly as you wish (unlike the normal <literal>imap</literal> command
    where <literal>timeout</literal> issues are involved). The characters are
    visible as you type them (unlike normal <literal>imap</literal>s) and you
    can use the movement or backspace key to correct yourself unlike normal
    mappings.
   </para>
  </note>
  <anchor id="place-holder" />
  <note id="place-holders">
   <title>Place Holders</title>
   <para>
    Almost all macros provided in &ls; implement Stephen Riem's bracketing
    system and Gergely Kontra's <literal>JumpFunc()</literal> for handling
    place-holders. This consists of using "place-holders" to mark off
    locations where the next relevant editing has to be done. As an example,
    when you type <literal>EFI</literal> in |insert-mode|, you will get the
    following:
    <programlisting>\begin{figure}[&lt;+htpb+&gt;]
    \centering
    \includegraphics{&lt;+file+&gt;}
    \caption{&lt;+caption text+&gt;}
    \label{fig:&lt;+label+&gt;}
\end{figure}&lt;++&gt;</programlisting>
    The text <literal>&lt;+htpb+&gt;</literal> will be selected and
    you will be left in |select-mode| so that you can continue typing
    straight away. After having typed in the placement specifier, you can press
    <literal>&lt;Ctrl-J&gt;</literal> (while still in insert-mode). This will
    take you directly to the next "place-holder". i.e, <literal>&lt;+file+&gt;</literal>
    will be visually selected with Vim in select mode
    again for typing in the file name. This saves on a lot of key presses.
   </para>

  <note id="overriding-macros">
   <title>Over-riding &ls; Macros</title>
   <para>
    If you wish to change these macros from their default values, for
    example, if you wish to change <literal>`w</literal> to expand to
    <literal>\wedge</literal> instead of its default expansion to
    <literal>\omega</literal>, you should use the <literal>IMAP</literal>
    function as described in the <link linkend="ls-new-macros">Using 
     IMAP()</link> section.
   </para>
   <para>
    An important thing to note is that if you wish to over-ride macros
    created by &ls; rather than merely create new macros, you should place
    the <literal>IMAP()</literal> calls in a script which gets sourced
    after the files in &ls;. A good place typically is as a file-type
    plugin file in the
    <literal>~/.vim/after/ftplugin/</literal> directory. (Use
    <literal>~/vimfiles</literal> if you are using
    <literal>WINDOWS</literal>). For example to over-ride
    <literal>`w</literal> to <literal>\wedge</literal> instead of
    <literal>\omega</literal>, place the following line in (say)
    <literal>~/.vim/after/ftplugin/tex_macros.vim</literal>:
    <programlisting>call IMAP('`w', '\wedge', 'tex')</programlisting>
    To delete a mapping, you can use
    <programlisting>call IUNMAP('FEM', 'tex')</programlisting>
    in <literal>~/.vim/after/ftplugin/tex_macros.vim</literal>.
   </para>
   <note>
    <para>
     It is important to use a file-name which will get sourced on a
     <literal>FileType</literal> event. Therefore you must use a file-name
     which conforms to the standards as described in
     <literal>|ftplugin-name|</literal>.
    </para>
   </note>
  </note>
  <note id="pausing-imaps">
   <title>Pausing Macro expansion</title>
   <para>
    If you wish to temporarily suspend the imaps functionality, then you
    can set the <literal>Imap_FreezeImap</literal> to 1. If you set
    <literal>g:Imap_FreezeImap</literal> to 1, then it will be a
    system-wide setting. Setting <literal>b:Imap_FreezeImap</literal> will
    affect only the current buffer.
   </para>
  </note>
  <para>
   The following sections describe the various editing macros provided
   by &ls;.
  </para>
  <section id="environment-mappings">
   <title>Environment Mappings</title>
   &ls; provides a rich set of mappings to insert, enclose and modify
   &latex; environments, i.e, <literal>\begin{...} ... \end{...}</literal>
   pairs.
   There are several possibilities for the customization of the inserted environments, see <link linkend="customizing-macros-environments">the section about customizations</link>.
   <section id="inserting-environments">
    <title>Inserting Environments</title>
    <para>
     &ls; provides the following ways to insert environments
    </para>
    <section id="inserting-env-f5">
     <title>Method 1: Pressing <literal>&lt;F5&gt;</literal></title>
     <para>
      If you press <literal>&lt;F5&gt;</literal> in the insert or normal
      mode while on an empty line, &ls; prompts you with a list of
      environments you might want to insert. You can either choose one
      from the list or type in a new environment name.  If you press
      <literal>&lt;F5&gt;</literal> on a line which already has a word,
      then that word is used instead of prompting.
     </para>
     <para>
      See <link linkend="Tex_Env_name">Tex_Env_name</link> for a
      description of how &ls; uses the word to form the expansion and how
      to modify &ls;'s behavior.
     </para>
     <para>
      The list of environments which &ls; prompts you with (when
      <literal>&lt;F5&gt;</literal> is pressed on an empty line) is formed
      from the <link
       linkend="Tex_PromptedEnvironments">Tex_PromptedEnvironments</link>
      setting.
     </para>
     <para>
      In addition to this setting, &ls; also lists environments found in
      custom packages as described in the section <link
       linkend="package-actions">Package actions.</link>
     </para>
    </section>
    <section id="inserting-env-shift-f1">
     <title>Method 2: Using <literal>&lt;S-F1&gt;</literal>-<literal>&lt;S-F4&gt;</literal></title>
     <para>
      The shifted function keys, <literal>&lt;S-F1&gt;</literal> to
      <literal>&lt;S-F4&gt;</literal> can be mapped to insert very commonly
      used environments. The environments mapped to each key can be
      customized via the <link
       linkend="Tex_HotKeyMappings">g:Tex_HotKeyMappings</link> setting.
     </para>
    </section>
    <section id="inserting-env-threeletter">
     <title>Method 3: Using three letter sequences</title>
     <para>
      Environments can also be inserted by pressing a 3 capital letter
      sequence starting with an <literal>E</literal>. The sequence of 3
      letters generally tries to follow the following rules:
     </para>
     <orderedlist>
      <listitem>
       All environment mappings begin with <literal>E</literal>
      </listitem>
      <listitem>
       If the environment can be broken up into 2 distinct words,
       such as flushright (flush + right), then the next 2 letters
       are the first letters of the 2 words.  Example:
       <programlisting>flushleft  (_f_lush + _l_eft)  ---&gt; EFL
flushright (_f_lush + _r_ight) ---&gt; EFR
minipage   (_m_ini  + _p_age)  ---&gt; EMP</programlisting>
       If on the other hand, the environment name cannot be broken
       up into 2 distinct words, then the next 2 letters are the
       first 2 letters of the name of the environment.
       Example:
       <programlisting>equation (_eq_uation)          ---&gt; EEQ</programlisting>
      </listitem>
     </orderedlist>
     <para>
      Unfortunately there are some environments that cannot be
      split in two words and first two letters in name are
      identical. In this case shortcut is created from E, first and
      last letter.  Example:
      <programlisting>quote     (_q_uot_e_)          ---&gt; EQE
quotation (_q_uotatio_n_)      ---&gt; EQN</programlisting>
      Of course, not every last one of the environments can follow
      this rule because of ambiguities. In case of doubt, pull down
      the Tex-Environments menu. The menu item should give the hint
      for the map.
     </para>
    </section>
   </section>
   <section id="enclosing-environments">
    <title>Enclosing in Environments</title>
    <para>
     &ls; provides visual-mode mappings which enclose visually
     selected portions of text in environments. There are two ways provided
     to do this.
    </para>
    <section id="enclosing-env-f5">
     <title>Method 1: Pressing <literal>&lt;F5&gt;</literal></title>
     <para>
      You can also select a portion of text visually and press
      <literal>&lt;F5&gt;</literal> while still in visual mode. This will
      prompt you with a list of environments. (This list can be customized
      via the <link
       linkend="Tex_PromptedEnvironments">g:Tex_PromptedEnvironments</link>
      setting). You can either choose from this list or type in a new
      environment name. Once the selection is done, &ls; encloses the
      visually selected portion in the chosen environment.
     </para>
    </section>
    <section id="enclosing-env-threeletter">
     <title>Method 2: Using three letter mappings</title>
     <para>
      You can also select text visually and press a sequence of three
      characters beginning with <literal>,</literal> (the single comma
      character) and the selected text will be enclosed in the chosen
      environment. The three letter sequence follows directly from the
      three letter sequence used to insert environments as described <link
       linkend="inserting-env-threeletter">here</link>. The following
      example describes the rule used:
     </para>
     <para>
      If <literal>ECE</literal> inserts a
      <literal>\begin{center}...\end{center}</literal> environment, then to
      enclose a block of selected text in
      <literal>\begin{center}...\end{center}</literal>, simply select the
      text and press <literal>,ce</literal>.  The rule simply says that the
      leading <literal>E</literal> is converted to <literal>,</literal> and
      the next 2 letters are small case.  
     </para>
    </section>
    <para>
     Some of the visual mode mappings are sensitive to whether you
     choose line-wise or character-wise. For example, if you choose a
     word and press <literal>,ce</literal>, then you get
     <literal>{\centering word}</literal>, whereas if you press
     <literal>,ce</literal> on a line-wise selection, you get:
     <programlisting>\begin{center}
    line
\end{center}</programlisting>
    </para>
   </section>
   <section id="changing-environments">
    <title>Changing Environments</title>
    <para>
     Pressing <literal>&lt;S-F5&gt;</literal> in normal mode detects which
     environment the cursor is presently located in and prompts you to
     replace it with a new one. The innermost environment is detected. For
     example, in the following source:
     <programlisting>\begin{equation}
  \begin{array}{ccc}
    2 &amp; 3 &amp; 4
  \end{array}
\end{equation}</programlisting>
     if you are located in the middle "2 &amp; 3 &amp; 4" line, then pressing
     <literal>&lt;S-F5&gt;</literal> will prompt you to change the array
     environment, not the equation environment. In addition, &ls; will also
     try to change lines within the environment to be consistent with the
     new environment. For example, if the original environment was an
     <literal>equation</literal> environment with a
     <literal>\label</literal> command, then changing it to an
     <literal>equation*</literal> environment will delete the
     <literal>\label</literal>.
    </para>
    <para>
     Pressing <literal>&lt;F5&gt;</literal> in normal mode has the same
     effect as pressing <literal>&lt;F5&gt;</literal> in insert-mode,
     namely you will be prompted to choose an environment to insert.

     Same as what happens to the Lower case, LaTeX does not support upper

    <para>
     Using <literal>IMAP</literal> instead of &vim;'s built-in
     <literal>:imap</literal> command has a couple of advantages:
     <orderedlist>
      <listitem>
       The 'ttimeout' option will generally limit how easily you can type
       the left hand side for a normal <literal>:imap</literal>. if you type
       the left hand side too slowly, then the mapping will not be
       activated.
      </listitem>
      <listitem>
       If you mistype one of the letters of the lhs, then the mapping is
       deactivated as soon as you backspace to correct the mistake.
      </listitem>
      <listitem>
       The characters in lhs are shown on top of each other. This is fairly
       distracting. This becomes a real annoyance when a lot of characters
       initiate mappings.
      </listitem>
     </orderedlist>

    <para>
     Formally, the syntax which is used for the <literal>IMAP</literal>
     function is:
     <programlisting>call IMAP (lhs, rhs, ft [, phs, phe])</programlisting>
    </para>

          <para>
           This is the "left-hand-side" of the mapping. When you use
           <literal>IMAP</literal>, only the last character of this word is
           actually mapped, although the effect is that the whole word is
           mapped.
          </para>
          <para>
           If you have two mappings which end in a common
           <literal>lhs</literal>, then the mapping with the longer
           <literal>lhs</literal> is used. For example, if you do
           <programlisting>call IMAP('BarFoo', 'something', 'tex')
call IMAP('Foo', 'something else', 'tex')</programlisting>
            Then typing <literal>BarFoo</literal> inserts
            <literal>"something"</literal>, whereas <literal>Foo</literal> by
            itself inserts <literal>"something else"</literal>.
          </para>
          <para>
           Also, the nature of <literal>IMAP()</literal> makes creating
           certain combination of mappings impossible. For example if you
           have
           <programlisting>call IMAP('foo', 'something', 'tex')
call IMAP('foobar', 'something else', 'tex')</programlisting>
           Then you will never be able to trigger <literal>"foobar"</literal>
           because typing <literal>"foo"</literal> will immediately insert
           <literal>"something"</literal>. This is the "cost" which you incur
           over the normal <literal>:imap</literal> command for the
           convenience of no 'timeout' problems, the ability to correct
           <literal>lhs</literal> etc.

           The "right-hand-side" of the mapping. This is the expansion you
           will get when you type <literal>lhs</literal>.
          </para>
          <para>
           This string can also contain special characters such as
           <literal>&lt;enter&gt;</literal> etc. To do this, you will need
           to specify the second argument in double-quotes as follows:
           <programlisting>:call IMAP('EFE', "\\begin{figure}\&lt;CR&gt;&ph;\\end{figure}&ph;", 'tex')</programlisting>
           With this, typing <literal>EFE</literal> is equivalent to typing
           in the right-hand side with all the special characters in
           insert-mode. This has the advantage that if you have filetype
           indentation set up, then the right hand side will also be
           indented just as if you had typed it in normally.
          </para>
          <anchor id="IMAP_PutTextWithMovement" />
          <para>
           You can also set up a &ls; style mapping which calls a custom function
           as follows:
           <programlisting>:call IMAP('FOO', "\&lt;C-r&gt;=MyFoonction()\&lt;CR&gt;", 'tex')</programlisting>
           where <literal>MyFoonction</literal> is a custom function you have
           written. If <literal>MyFoonction</literal> also has to return a string
           containing <literal>&ph;</literal> characters, then you will need to
           use the function <literal>IMAP_PutTextWithMovement()</literal>. An
           example best explains the usage:
          </para>
          <programlisting>call IMAP('FOO', "\&lt;C-r&gt;=AskVimFunc()\&lt;CR&gt;", 'vim')

   &ls; has a lot of functionality written to ease working with packages.
   Packages here refers to files which you include into the &latex;
   document using the <literal>\usepackage</literal> command.
  </para>
  <section id="inserting-packages">
   <title>Inserting package commands</title>
   <para>
    When you first invoke &ls;, it scans the
    <literal>$VIM/ftplugin/latex-suite/packages</literal> directory for
    package script files and creates a menu from all the files found there.
    This menu is created under <literal>TeX-Suite > Packages >
     Supported</literal>. This menu contains a list of packages "supported"
    by &ls;. When you choose one of the packages from this menu (for example
    the <literal>amsmath</literal> package), then a line of
    the form
    <programlisting>\usepackage[&ph;]{amsmath}&ph;</programlisting>
    will be inserted into the current file.
   </para>
   <para>
    The <literal>\usepackage</literal> line can also be inserted in an easy
    manner in the current file by pressing <literal>&lt;F5&gt;</literal>
    while in the preamble of the current document. This will set up a prompt
    from the supported packages and ask you to choose from one of them. If
    you do not find the package you want to insert in the list, you can type
    in a package-name and it will use that. Pressing
    <literal>&lt;F5&gt;</literal> in the preamble on a line containing a
    single word will construct a <literal>\usepackage</literal> line from
    that word.
   </para>
   <para>
    You can also use the <link
     linkend="TPackage"><literal>TPackage</literal></link> to insert the
    <literal>\usepackage</literal> line.
   </para>
   <para>
    Once you have inserted a <literal>\usepackage</literal> line, for
    supported packages, you can use the Options and Commands menus

   <para>
    where <literal>&lt;package&gt;</literal> is the package you just

    environments and options which &ls; recognizes as belonging to this
    package.
   </para>
   <note>
    <para>
     While inserting an option, you need to position yourself in the
     appropriate place in the document, most commonly inside the square
     braces in the <literal>\usepackage[]{packname}</literal> command. &ls;
     will not navigate to that location.
    </para>
   </note>
   <para>
    In addition to creating these sub-menus, &ls; will also scan the
    <literal>$VIM/ftplugin/latex-suite/dictionaries</literal> directory and
    if a dictionary file corresponding to the package file is found, then
    it will add the file to the <literal>'dict'</literal> setting in &vim;
    so you can use the <literal>&lt;C-X&gt;&lt;C-K&gt;</literal> command to
    complete words from that file.

    If a package detected at startup is found by &ls; in the current

    scan the package for <literal>\newenvironment</literal> and

    Whenever &ls; begins editing a new &latex; file, it scans it for

    <title>Custom Packages</title>
    <para>
     Often times, the preamble can become too long, and some people prefer
     to put most of their personalization in a custom package and include
     that using a <literal>\usepackage</literal> line. &ls; tries to search
     such customs package for other <literal>\usepackage</literal> lines, so
     that supported packages included in this indirect manner can also be
     used to create sub-menus, extend the <literal>'dict'</literal> setting
     etc. The most obvious place to place such custom packages is in the
     same directory as the edited file. In addition, &latex; also supports
     placing custom packages in places pointed to by the
     <literal>$TEXINPUTS</literal> environment variable.
    </para>
    <para>
     If you use the <literal>$TEXINPUTS</literal> variable in &latex;, and
     you wish &ls; to search these custom packages for
     <literal>\usepackage</literal> lines, then you need to initialize the
     <link linkend="Tex_TEXINPUTS"><literal>g:Tex_TEXINPUTS</literal></link>
     variable.
    </para>
    <para>
     The <literal>g:Tex_TEXINPUTS</literal> variable needs to be set in the
     same format which &vim; uses for the <literal>'path'</literal> setting.
     This format is explained in detail if you do 
     <programlisting>:help file-searching</programlisting>
     from within &vim;.
    </para>
    <para>
     Therefore the value of <literal>g:Tex_TEXINPUTS</literal> will most
     probably be different from <literal>$TEXINPUTS</literal> which your
     native &latex; distribution uses.
    </para>
    <para>
     Example:
     <programlisting>let g:Tex_TEXINPUTS = '~/texmf/mypackages/**,./**'</programlisting>
     The <literal>**</literal> indicates that all directories below the
     directory <literal>~/texmf/mypackages</literal> and
     <literal>./</literal> are to be scanned for custom packages.
    </para>
    <note>
     <para>
      The present directory <literal>'.'</literal> is always searched. You

    Supporting a package is easy and consists of writing a vim script with
    the same name as the package and placing it in the
    <literal>$VIM/ftplugin/latex-suite/packages</literal> directory. A
    package script should define two variables as described in the next two
    sections. In addition to these two variables, you can also define any

     Example:

     The <literal>=</literal> suffix means that the option takes a value.
     Use <literal>sbr:group name</literal> to separate options into
     sub-menus. All successive options will be clubbed into the

Here is short summary of prefixes which can be used in package files:
(x - place with cursor, &ph; - |placeholder|)

{env:command}  Environment: creates simple environment template
            \begin{command}
                x

            \end{command}&ph;
{bra:command} Brackets:

{brs:command[&lt;&lt;option&gt;&gt;]...} Brackets special (as environment special:
            \command[&lt;+x+&gt;]{&ph;}{&ph;}&ph;
{nor:command} Normal:
            \command&lt;Space
{noo:command} Normal with option:
            \command[x]&ph;
{nob:command} Normal with option and brackets:
            \command[x]{&ph;}&ph;
{pla:command} Plain:
            command&lt;Space
{spe:command} Special:
            command   &lt;-literal insertion of command
{sep:command} creates separator. Good for aesthetics and usability :)
{sbr:command} Breaks menu into submenus. &lt;command&gt; will be title of submenu.
            Can be used also in package variable.

Command can be also given without prefix:. The result is
           \command

  <title>Latex Completion</title>
  <para>
   &ls; provides an easy way to insert references to labels and
   bibliographic entries and also provide filename arguments to commands
   such as <literal>\includegraphics</literal>. Although the completion
   capabilities are very diverse, &ls; only uses a single key
   (<literal>&lt;F9&gt;</literal> by default) to do all of it. Pressing the
   <literal>&lt;F9&gt;</literal> key does different things based on where
   you are located. &ls; tries to guess what you might be trying to
   complete at the location where you pressed
   <literal>&lt;F9&gt;</literal>. For example, pressing
   <literal>&lt;F9&gt;</literal> when you are within a
   <literal>\ref</literal> command will try to list the
   <literal>\label</literal>'s in the present directory. Pressing it when
   you are in a <literal>\cite</literal> command will list bibliography
   keys. &ls; also recognizes commands which need a file name argument and
   will put up an explorer window for you to choose a filename.
  </para>
  <note id="ls-set-grepprg">
   <title>Before you start with &ls;'s completion function...</title>
   <para>
    Most of &ls;'s completion capabilities depend on the
    python interface of vim.
    Both python2 and python3 are supported.
    Hence,
    <programlisting>python print "Hello."</programlisting>
    or
    <programlisting>python3 print("Hello.")</programlisting>
    should work.

   <title>&ls; <literal>\ref</literal> completion</title>
   <para>
    Pressing <literal>&lt;F9&gt;</literal> when you are within a partially
    completed <literal>\ref</literal> command will split open a window
    (named <literal>__OUTLINE__</literal>) which contains a nicely
    formatted list of all the <literal>\label</literal>s found in the
    present project.  The <literal>\label</literal>s are heirarchically
    arranged according to which <literal>\section</literal>,
    <literal>\subsection</literal> etc of the overall document structure
    they are present in. For example, when you first press
    <literal>&lt;F9&gt;</literal> after typing <literal>\ref{</literal>,
    you should see something like:
    <programlisting>

+-- 98 lines: 3. Aerodynamics of the MFI thorax------------
+-- 40 lines: 4. Jump Resonance in Fourbar Mechanisms------
+-- 28 lines: 5. Design and Fabrication Issues-------------
    </programlisting>
    Each chapter is |fold|ed away so that you can quickly jump to the
    correct section/subsection in which the relevant equation is defined.
    This makes inserting references significantly faster for large projects
    with hundreds of equations. You can then open some of the folds to see
    for example:

     You can press <literal>&lt;F9&gt;</literal> after typing part of the

     <literal>\label</literal>s which begin with the already filled

     tables etc. if you consistently label equations to begin with
     <literal>eqn:</literal>, figures to begin with <literal>fig:</literal>
     etc. For example, with this scheme, pressing

    &ls; provides an easy way to insert references to bibliographic
    entries. Pressing <literal>&lt;F9&gt;</literal> when the cursor is
    placed inside a partially completed <literal>\cite</literal> command
    will split open a new window (named <literal>__OUTLINE__</literal>)
    which contains a formatted and syntax highlighted list of all bibtex
    entries found. For example, pressing <literal>&lt;F9&gt;</literal>
    after typing <literal>\ref{</literal> should present you with a window
    which looks something like this:
    <programlisting>

    You can easily jump from one entry to another using the
    <literal>'n'</literal> and <literal>'p'</literal> keys (to go to the
    next / previous entry respectively).
   </para>
   <para>
    You can also filter out a subset of the bibtex entries by pressing
    <literal>'f'</literal> while in this window. Doing this presents the
    following prompt:

Field acronyms: (`:let g:Tex_EchoBibFields = 0` to avoid this message)
 [t] title         [a] author        [b] booktitle

 (you can also enter the complete field name)
Enter filter criterion [field&lt;space&gt;value]:
    </programlisting>
    At the prompt, type
    <programlisting>a ellington</programlisting>
    Notice that the letter a is an acronym for <literal>author</literal>
    according to the prompt above. Therefore this filter only shows those
    bibtex entries whose author field contains the text
    <literal>ellington</literal>. You can keep narrowing your selection by
    repeatedly filtering the results. If you would like to remove all the
    filters and see all entries again, press 'a', which removes
    all the filters.
   </para>
   <para>
    You can also sort the bibtex entries based on a field. To do this,
    press 's'. This will present you with a prompt like in the case of the
    filter and you are asked to choose a field. In this case, you would
    type in a single character. This sorts the entries according to that
    field.
   </para>
   <note>
    <para>
    <literal>&lt;F9&gt;</literal> will also work in a similar way after any
    command which contains the word <literal>cite</literal> in it. For

   This runs latex on the current file and displays the errors in a
   |quickfix-window| below the file being edited. You can then scroll
   through the errors and press <literal>&lt;enter&gt;</literal> to be
   taken to the location of the corresponding error. Along with the errors

   <title>Setting Compilation rules</title>
   <para>
    In order to compile &latex; files into various formats, &ls; needs to know
    which external programs to call and in which way they need to be called.
    This information is provided to &ls; via a number of "rules". For each
    format you want to compile to, you need to specify a rule. A rule is
    specified by defining a variable of the form:
    <programlisting>g:Tex_CompileRule_&lt;format&gt;</programlisting>
    where <literal>&lt;format&gt;</literal> is a string like
    <literal>"pdf"</literal>, <literal>"dvi"</literal> etc.
   </para>
   <para>
    Example: By default, &ls; uses the following rule for compiling &latex;
    documents into DVI.
    <programlisting>g:Tex_CompileRule_dvi = 'latex --interaction=nonstopmode $*'</programlisting>
   </para>

   <note>
    <para>
     For win32 users user MikTeX, sometimes the latex compiler's output has a

  <section id="compiler-dependency">
   <title>Handling dependencies in compilation</title>
   <para>
    &ls; also handles compiling dependencies automatically via certain
    rules which specify the "dependency chain" for each target format. 
    For example, if in your case, you use
    <programlisting>.tex -&gt; .dvi -&gt; .ps -&gt; .pdf</programlisting>
    to generate <literal>pdf</literal> files from <literal>dvi</literal>
    files, then you will need to specify the following setting in your
    &ls; configuration (see <link
     linkend="customizing-latex-suite">customizing &ls;</link> for where
    these settings should go):
    <programlisting>
let g:Tex_FormatDependency_pdf = 'dvi,ps,pdf'
</programlisting>
    This is a comma separated string of formats specifying the order in
    which the formats to be compiled into should be chosen.  With this
    setting, if you set the target format to <literal>pdf</literal>, then
    the next time you compile via the <literal>\ll</literal> shortcut, &ls;
    will first generate a <literal>dvi</literal> file, then use that to
    generate the <literal>ps</literal> file and finally create the
    <literal>pdf</literal> file from that.
   </para>
   <note>
    <para>
     If any of the intermediate formats is listed in the
     <literal>g:Tex_MultipleCompileFormats</literal> setting as described
     in the section <link linkend="compiling-multiple">Compiling multiple
      times</link>, then &ls; might make multiple calls to the compiler to
     generate the output file of that format.
    </para>
   </note>
   <para>
    Along with the <literal>g:Tex_FormatDependency_{format}</literal>
    setting, you should ofcourse specify the rule for compiling to each of
    the formats as described in the <link linkend="compiler-rules">previous
    section</link>. For example, with the setting above, you could use:
    <programlisting>
let g:Tex_CompileRule_dvi = 'latex --interaction=nonstopmode $*'
let g:Tex_CompileRule_ps = 'dvips -Ppdf -o $*.ps $*.dvi'
let g:Tex_CompileRule_pdf = 'ps2pdf $*.ps'</programlisting>
   </para>
   <note>
    <para>
     By default, &ls; does not specify any compiler dependencies. Each
     target format for which a rule has been derived will be compiled
     independently.

    For example, when <literal>\label</literal>'s change, when new

    you are compiling to requires multiple compilations, then you will

  <section id="compiler-output-customization">
   <title>Customizing the compiler output</title>
   <para>
    Most &latex; compilers produce a very large amount of output during
    compilation, most of which is not relevant to debugging type-setting
    errors. The compiler plugin provided with &ls; (which is an enhanced
    version of the standard compiler plugin maintained by Artem Chuprina),
    provides a way to filter the compiler output so that the actual
    errors/warnings can be presented much more concisely.
   </para>
   <para>
    The compiler plugin is set up by default to function in a "non-verbose",
    "ignore-common-warnings" mode, which means that irrelevant lines from the
    compiler output will be ignored and some very common warnings are also
    ignored.
    &ls; does this via the global variable <link
     linkend="Tex_IgnoredWarnings"><literal>g:Tex_IgnoredWarnings</literal></link>.
    This is a list of patterns, which can be used to filter out (or ignore)
    some or the warnings and errors reported by the compiler. See the link
    above for its default value.
   </para>
   <para>
    &ls; uses the <link
     linkend="Tex_IgnoreLevel"><literal>g:Tex_IgnoreLevel</literal></link>
    setting to set a default ignore level. For example, for the default
    value of 4, &ls; ignores warnings and errors matching the first 4
    patterns in <literal>g:Tex_IgnoredWarnings</literal>.
   </para>
   <para>
    In addition to setting a default value of the ignore level, &ls;
    provides the ability to set the level dynamically, using the
    <literal>TCLevel</literal> command. For example, if you issue the
    command:
    <programlisting>TCLevel 3</programlisting>
    from within &vim;, then the next time you compile the document, &ls; will
    ignore warnings and errors which match the first three patterns in
    <literal>g:Tex_IgnoredWarnings</literal>.
   </para>
   <para>
    When TCLevel is called with the unquoted string strict as follows:
    <programlisting>TClevel strict</programlisting>
    then &ls; switches to a "verbose", "no-lines-ignored" mode which is useful
    when you want to make final checks of your document and want to be careful
    not to let things slip by.
   </para>
   <para>
    See the explanation of the settings <link
     linkend="Tex_IgnoredWarnings">g:Tex_IgnoredWarnings</link> and <link
     linkend="Tex_IgnoreLevel">g:Tex_IgnoreLevel</link> to find out how to
    customize the filtering done by &ls;

  <section id="part-compiling">
   <title>Compiling parts of a file</title>

    &ls; also provides a way to compile a fragment of a document. This can be
    very useful while debugging a complex equation or one chapter in a book,

    To do this, visually select a portion of the text and press
    <literal>\ll</literal> while in visual mode. The visually selected portion
    will be saved to a temporary file with the preamble from the current
    document prepended. &ls; will then switch focus to this temporary file and

    portion of the original file with this one.

    for part compilation will reside in the same directory as the file from

   <para>
    In order to view the output files created by compiling the source
    files, you need to specify which external program &ls; should call. You
    can specify the external program using one of two settings
    <link linkend="Tex_ViewRule_format">Tex_ViewRule_format</link> or <link
     linkend="Tex_ViewRuleComplete_format">Tex_ViewRuleComplete_format</link>.
    By default, &ls; has default settings for viewing various common output
    formats via the <literal>Tex_ViewRule_format</literal> settings, so
    that if you are using commonly used programs, you should be all set to
    view compiled files from within &vim; by simply pressing
    <literal>\lv</literal>.
   </para>
   <note>
    <para>
     The viewing function also takes the <link
      linkend="latex-master-file"><literal>*.latexmain</literal></link> file
     into account to decide which file to show.
    </para>
   </note>
   <para>
    If pressing <literal>\lv</literal> does not work, then it most probably
    has to do with incorrect settings of the <link
     linkend="Tex_ViewRule_format"><literal>g:Tex_ViewRule_&lt;format&gt;</literal></link>
    where <literal>&lt;format&gt;</literal> is the format you are
    attempting to view. See the link above for how to set this according to
    your system.
   </para>
   <note>
    <para>
     On Windows and OS/X, you can leave the view rule empty to open the document
     with the default viewer on your system. On Linux/UNIX systems, you can use
     the <literal>xdg-open</literal> command to open the document with the default
     viewer.

   <para>
    In addition to viewing the files, &ls; also supports forward and inverse
    searching for certain common tools for viewing documents.
    See the next few sections for details on forward and inverse searching,
    including an overview of viewers.

    Forward searching refers to making a viewer display a given document at

    forward searching, but viewers that are not listed here may work, too:

    <title>Enabling Forward and Inverse Searching</title>
    <para>
     Most DVI viewers need "source-special" information in order to do
     forward (and inverse) searching. This information is embedded in the
     <literal>dvi</literal> file if the &latex; source is compiled with the
     <literal>--src-specials</literal> option. By default, &ls; does not
     supply this argument to the compiler. See the section on
     <literal><link
       linkend="Tex_CompileRule_format">g:Tex_CompileRule_dvi</link></literal>
     to find out how this option can be set.
    </para>
    <para>
     Pdf viewers usually use a synctex(.gz) file. This can be enabled with the compiler flag
     <programlisting>-synctex=1</programlisting> for pdflatex. 
     Within this suite it is however enabled by default, unless you change 
     <literal><link linkend="Tex_CompileRule_format">g:Tex_CompileRule_pdf</link></literal>. 
    </para>

  <section id="inverse-searching">
   <title>Inverse Searching</title>
   <para>
    Inverse searching refers to a viewer (either <literal>pdf</literal> or <literal>dvi</literal>)
    telling &vim; to display the &latex; source file at a given location. 
    Usually this happens with double-clicking or clicking while pressing the shift/control button
    in the viewer window. The actual method depends on the viewer application.
   </para>
   <para>
    You will need to <link linkend="enabling-searching">enable
     searching</link> in order to use this functionality.
   </para>
   <para>
    You will also need to specify certain settings to the viewer
    conveying the syntax which it needs to use to tell &vim; how to display
    the source file. 
   </para>
   <para>
    In windows you need to supply the following command in the apporpriate setting of your viewer:
    <programlisting>"C:\Program Files\vim\vim74\gvim" -c ":RemoteOpen +%l %f"</programlisting>
    Or if you have (g)&vim; added to your <literal>$PATH</literal> simply:
    <programlisting>gvim -c ":RemoteOpen +%l %f"</programlisting>
    The command <literal>:RemoteOpen</literal> is supplied when you install
    &ls;. In <literal>YAP</literal>, you can set this option under
    <literal>View > Options > Inverse Search</literal> in the Command Line field.
    And in <literal>SumatraPdf</literal> you can set this option under
    <literal>Settings > Options > Set inverse search command-line</literal>.
   </para>
   <para>
    On *nix machines, &ls; attempts to call the DVI viewer in such a way
    that it already knows how to communicate with &vim;. If this does not
    seem to be working, you can use the <literal>RemoteOpen</literal>
    command described above.

  <title>Latex Folding</title>
  <para>
   &ls; ships with the plugin SyntaxFolds.vim which is a plugin for
   creating "fake" syntax folds on the fly. The fold method is actually manual
   but the folding is based on &latex; syntax. This offers a speed increase over
   regular syntax folding. Ofcourse it has the disadvantage that the folds are
   not dynamic, i.e newly created syntax items are not automatically folded up.
   (This is a compromise between speed and convenience).
  </para>
  <para>
   When you open up a LaTeX file, all the portions will be automatically folded
   up. However, no new folds will be created until you press
   <literal>\rf</literal>. (rf
   stands for "refresh folds").
  </para>
  <para>
   The fold-text is set to the first line of the folded text unless the fold is a
   table, figure etc. (an environment). In this case, if a \caption and/or a
   label is found in the folded region, then those are used to make a more
   meaningful fold-text, otherwise the second line of the environment is displayed
   along with the name of the environment. In other words, the following
   <programlisting>\begin{figure}[h]
     \centering

     The <literal>%%fakesection</literal> section is
     provided as a means for the user to group lines into "fake" sections.
     In particular, it is useful to fold the introduction of a <literal>section</literal>
     that is not part of a <literal>subsection</literal>:
     <programlisting>
\section{Latex-Suite}
%%fakesubsection Introduction

     This entry defines which commands will be folded. It is a comma

     The default setting is empty, i.e no commands are folded.
     The words need not be standard Latex commands. You can use whatever
     words you like. Each word will fold all commands whose name begins
     with that word as in the case of the <link

    </para>
    <note>
     <para>
      It is very difficult to fold commands reliably because it is very
      difficult to create a regexp which will match a line containing
      unmatched parentheses (or curly brackets), but will not match a line
      containing matched parentheses.
     </para>
     <para>
      Just to make things safer, only lines which start a command but do
      not contain additional curly braces after the command has started are
      folded. In other words, if you wanted to fold the the command
      <literal>"mycommand"</literal>, then the  lines
      <programlisting>\mycommand{This is a line
and some more text on the next line
}</programlisting>
      will be folded, but the lines
      <programlisting>\mycommand{This is a \textbf{line}
and some more text
}</programlisting>
      will not be folded. This is a bug which is very difficult to fix.
     </para>
     <para>
      Similarly, a command fold will stop at the first line containing a '}',
      even if this brace does not correspond to the opening brace of the command.

     The order of the words in the <literal>Tex_FoldedXXXX</literal>
     variables is <emphasis>important</emphasis>. The order defines the
     order in which the folds are nested. For example, the value
     <literal>"subsection,section"</literal> for the
     <literal>Tex_FoldedSections</literal> variable will not fold any
     subsections at all. This is because the folds are created in the
     <emphasis>reverse</emphasis> order in which they occur in the
     <literal>Tex_FoldedSections</literal> setting and also, once a fold is
     created, the interior of the fold is not examined for creating
     additional folds. In the above case, this means that a
     <literal>\section</literal> is folded first and then its interior is
     not examined further. The correct value should have been
     <literal>"section,subsection"</literal>

     Each of the fold setting variables
     <literal>Tex_FoldedSections</literal>,
     <literal>Tex_FoldedEnvironments</literal> etc., as explained previously
     is a comma separated string of variables. However, to make it easier
     to <emphasis>add</emphasis> to the default settings without having to
     repeat the whole default setting again, &ls; uses the following logic
     in forming the complete setting string from the
     <literal>Tex_FoldedXXXX</literal> variables. If the variable starts with
     a comma, then <literal>Tex_FoldedXXXX</literal> is added to the end of
     the default string rather than replacing it. Similarly, if it ends
     with a comma, then it will be prepended to the beginning of the
     default setting rather than replacing it.
    </para>
    <para>
     For example, if <literal>Tex_FoldedEnvironments</literal> is set to the
     string <literal>"myenv"</literal>, then only an environment of the
     form <literal>\begin{myenv}</literal> will be folded. However, if the
     <literal>Tex_FoldedEnvironments</literal> setting is
     <literal>",myenv"</literal>, then the <literal>\begin{myenv}</literal>
     environment will be folded after all other environments in the default
     setting have been folded. On the other hand if
     <literal>Tex_FoldedEnvironments</literal> is of the form
     <literal>"myenv,"</literal>, the <literal>\begin{myenv}</literal>
     environment will be folded before the rest of the environments in the
     default setting.

  <para>
   Each time &ls; opens a new &latex; file, it will try to see if it is
   part of a multiple file project by searching upwards (to the root of
   the file-system) from the current file's directory to see if it finds a
   file of the form <literal>*.latexmain</literal>. If such a file is
   found, then it is considered that the current file is part of a larger
   project. The name of the &latex; master file is inferred directly from
   the first part of the <literal>*.latexmain</literal> file as described
   in the example above.

    If a <link linkend="latex-master-file">master file</link> is found,
    then &ls; <literal>:source</literal>s the file. Thus this file needs to
    contain valid &vim; commands. This file is typically used to store
    project specific settings.

    In the example described <link

    <literal>intro/intro.tex</literal> and press <literal>\ll</literal>,
    then you still want &ls; to compile <literal>main.tex</literal>,
    because <literal>intro/intro.tex</literal> is merely a fragment which
    is <literal>\input</literal>'ed into <literal>main.tex</literal>. If
    the master file is already specified using the
    <literal>*.latexmain</literal> convention described <link
     linkend="latex-project-example">previously</link>, then &ls; will automatically
    compile the master file when you are editing any of its

    If you wish to use some different logic to specify the main file name,
    you can specify a custom expression via the
    <literal>Tex_MainFileExpression</literal> variable. This is a string

    <literal>modifier</literal> which is in the format used for
    <literal>|filename-modifiers|</literal>, for example,
    <literal>':p:h'</literal>. You should utilize this variable to modify
    the filename of the main file.

   <title>&ls; Maps</title>
   <anchor id="remapping-latex-suite-keys" />
   <para>
    Most of the mappings used in &ls; can be mapped to a different key
    combination to suit your particular needs. An example best explains the
    procedure for doing this. Suppose you want to remap the
    <literal>&lt;C-j&gt;</literal> key which &ls; (actually imaps.vim) uses
    to jump to the next placeholder. To do this, you first need to find out
    which <literal>&lt;Plug&gt;</literal> mapping
    <literal>&lt;C-j&gt;</literal> is derived from. You will need to look
    at the relevant section of this manual to do this. For example, the
    section <link linkend="customize-imap-maps">IMAP mappings</link> has
    the information that the <literal>&lt;C-j&gt;</literal> key is derived
    from <literal>&lt;Plug&gt;IMAP_JumpForward</literal>. Therefore to
    remap the <literal>&lt;C-j&gt;</literal> key to say
    <literal>&lt;C-space&gt;</literal>, you will need to put a
    statement like the following in your <literal>~/.vimrc</literal>.
    <programlisting>imap &lt;C-space&gt; &lt;Plug&gt;IMAP_JumpForward</programlisting>
   </para>
   <note>
    <para>
     To change the <literal>IMAP</literal> mappings which affect jumping
     between placeholders, the <literal>map</literal> statement above has
     to be placed in your <literal>~/.vimrc</literal>. For other mappings
     you can place the <literal>map</literal> statement in your
     <literal>$VIM/ftplugin/tex.vim</literal> file.  The reason for this is
     that the <literal>&lt;C-j&gt;</literal> maps are created in
     <literal>plugin/imaps.vim</literal>, which is sourced as soon as &vim;
     starts before sourcing any ftplugin files.

      <para>
       If you wish to wish to expand certain environments differently from
       the way &ls; does it, you can define custom expansions using global
       variables of the form <literal>Tex_Env_{name}</literal> where
       <literal>name</literal> corresponds to the environment.
      </para>
      <para>
       For example, if you press <literal>&lt;F5&gt;</literal> after typing
       <literal>theorem</literal>, &ls; will by default expand it to
       <programlisting>\begin{theorem}
      \label{&ph;}&ph;
\end{theorem}&ph;</programlisting>
        However, if you wish change this to
       <programlisting>\begin{theorem}
      &ph;
\end{theorem}&ph;</programlisting>
        then define the following variable
       <programlisting>let g:Tex_Env_theorem = "\\begin{theorem}\&lt;CR&gt;&ph;\&lt;CR&gt;\\end{theorem}"</programlisting>
       </para>
      <para>
       If the expansion uses special keys such as carriage return etc, then
       use double-quotes and use the <literal>"\&lt;key&gt;"</literal>
       notation for special keys. Backslashes have to be doubled.
      </para>
      <para>
       You could even use strings returned by functions as the expansion by
       using the <link
        linkend="IMAP_PutTextWithMovement">IMAP_PutTextWithMovement()</link>
       function.
      </para>
      <para>
       If the name of the environment contains special characters (for
       example, the <literal>align*</literal> environment), then use the
       following form:
       <programlisting>let g:Tex_Env_{'align*'} =
         \ "\\begin{align*}\&lt;CR&gt;&ph; &amp;= &ph;\&lt;CR&gt;\\end{align*}&ph;"</programlisting>
        This will make pressing <literal>&lt;F5&gt;</literal> after
        <literal>align*</literal> expand to
        <programlisting>\begin{align*}
     &ph; &amp;= &ph;
 \end{align*}&ph;</programlisting>

    </section>
    <section id="Tex_Env_name_aliasto">
     <title>Tex_Env_name_aliasto</title>
      <para>
       You may use this variable to set an alias to another environment.
      </para>
      <para>
       For example, if you use the above mentioned <literal>theorem</literal>
       environment a lot and want to save yourself from typing in the whole
       word everytime you use the environment, you may set
       <programlisting>
let g:Tex_Env_tr_aliasto = "theorem"</programlisting>
       And next time you type <literal>tr</literal> and then press
       <literal>&lt;F5&gt;</literal>, &ls; will expand it to either the default
       <literal>theorem</literal> environment or the <literal>theorem</literal>
       defined by you, based on whether <literal>g:Tex_Env_theorem</literal>
       has been set.
      </para>
      <para>
       If you try to expand to an environment that is neither built-in, nor defined
       by you, &ls; would simply wrap it up with a barebone environment like:
        <programlisting>
\begin{expanded_name}
    &lt;++&gt;
\end{expanded_name}&lt;++&gt;</programlisting>
      </para>
      <para>
       And if an alias happen to have the same name with another environment, the
       alias precedes the environment.

    <section id="Tex_EnvLabelprefix_name">
     <title>Tex_EnvLabelprefix_name</title>
      <para>
       By default, &ls; inserts labels without prefixes.
       The setting <literal>Tex_EnvLabelprefix_{name}</literal>, where <literal>name</literal>
       corresponds to the environment, is used to create labels with prefixes automatically.
       For instance, if you use
       <programlisting>
let g:Tex_EnvLabelprefix_equation = "eq:"</programlisting>
       the prefix <literal>eq:</literal> is inserted in all labels in generated equations:
       <programlisting>
\begin{equation}
      &ph;

       This setting works for the environments

     With so many visual maps, its helpful to have a way of catching typing
     errors made in visual mode. What this does is to prompt you to correct
     your visual mode mapping if you start out with <literal><link
       linkend="Tex_Leader">g:Tex_Leader</link></literal> and then type some
     illegal keys. It basically maps just the <literal>g:Tex_Leader</literal>

     For Macintosh systems, these strings are left empty by default. This lets
     the system pick the program for each format. If you define these variables
     for Mac, the system choice will be over-ridden.
    </para>
    <para>
     &ls; appends <literal>file.format</literal> to the above settings
     while calling the external programs. For example, with
     <programlisting>let g:Tex_ViewRule_dvi = 'yap -1'</programlisting>
     <literal>yap</literal> is called as 
     <programlisting>!start yap -1 file.dvi</programlisting> from within
     &vim;. (The initial <literal>start</literal> is used on
     <literal>Windows</literal> platforms is to make <literal>yap</literal>
     start as a separate process.) If you find the way &ls; constructs the
     command line too restrictive, you can use the <link
      linkend="Tex_ViewRuleComplete_format"><literal>Tex_ViewRuleComplete_format</literal></link>
     setting for more complete control on how the command line is
     constructed while calling the external program for viewing.
    </para>
    <note>
     <para>
      For windows, you will need to set the <literal>$PATH</literal> variable
      to include the paths to <literal>yap</literal>,
      <literal>AcroRd32</literal>, <literal>gsview32</literal> and any other
      programs. See your system documentation for how to do this.

     <literal>Tex_ViewRuleComplete_format</literal> takes precedence over

     <literal>Tex_ViewRuleComplete_format</literal> for any

      Make sure you make the process go into the background otherwise vim

      again.
     </para>
     <para>
      To make a process go into the background on a <literal>*nix</literal>
      platform, use a trailing <literal>&amp;</literal> in the setting. On
      <literal>Windows</literal>, use <literal>start</literal> at the
      beginning of the setting. Example: Suppose you have a latex->html
      converter which converts a file say foo.tex to a file foo/index.html.
      Then you would use:
      <programlisting>" On *nix platform
let g:Tex_ViewRuleComplete_html = 'MozillaFirebird $*/index.html &amp;'
" On windows platform
let g:Tex_ViewRuleComplete_html = 'start MozillaFirebird $*/index.html'</programlisting>
