Latex-Suite utilizes a set of macros originally created by Carl Mueller in
auctex.vim to make inserting all the <code class="literal">\left ... \right</code>
stuff very easy and to also make some use of the heavily under-utilized
<code class="literal"><Alt></code> key.
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
By default, typing <code class="literal">Alt-<key></code> in Vim takes
focus to the menu bar if a menu with the hotkey
<code class="literal"><key></code> exists. If in your case, there are
conflicts due to this behavior, you will need to set
</p><pre class="programlisting">set winaltkeys=no</pre><p>
in your <code class="literal">$VIM/ftplugin/tex.vim</code> in order to use these
maps.
</p></div><div class="note" title="Customizing the maps" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Customizing the maps</h3><p>
If for some reason, you wish to not map the
<code class="literal"><Alt></code> keys, (some European users need to use
the <code class="literal"><Alt></code> key to enter diacritics), you can
change these maps to other keys as described in the section <a class="link" href="latex-suite-maps.html#customize-alt-key-maps" title="10.1.2 Alt-Key mappings">Customizing Alt-key maps</a>.
</p></div><div class="section" title="3.10.1 <Alt-L>"><div class="titlepage"><div><div><h4 class="title"><a id="Alt-L"></a>3.10.1 <code class="literal"><Alt-L></code></h4></div></div></div><p>
This is a polymorphic insert-mode mapping which expands to one of the
following depending on the character just before the cursor location.
</p><div class="informaltable"><table border="1"><colgroup><col width="0.5in" align="cener"></col><col width="0.5in"></col></colgroup><thead><tr><th align="cener">Character before cursor</th><th>Expansion</th></tr></thead><tbody><tr><td align="cener">(</td><td><code class="literal">\left( <++> \right)</code></td></tr><tr><td align="cener">[</td><td><code class="literal">\left[ <++> \right]</code></td></tr><tr><td align="cener">|</td><td><code class="literal">\left| <++> \right|</code></td></tr><tr><td align="cener">{</td><td><code class="literal">\left\{ <++> \right\}</code></td></tr><tr><td align="cener"><</td><td><code class="literal">\langle <++> \rangle</code></td></tr><tr><td align="cener">q</td><td><code class="literal">\lefteqn{<++>}<++></code></td></tr></tbody></table></div><p>
If the character before the cursor is none of the above, then it will
simply insert a <code class="literal">\label{<++>}<++></code>.
</p></div><div class="section" title="3.10.2 <Alt-B>"><div class="titlepage"><div><div><h4 class="title"><a id="Alt-B"></a>3.10.2 <code class="literal"><Alt-B></code></h4></div></div></div><p>
This insert-mode mapping encloses the previous character in
<code class="literal">\mathbf{}</code>.
</p></div><div class="section" title="3.10.3 <Alt-C>"><div class="titlepage"><div><div><h4 class="title"><a id="Alt-C"></a>3.10.3 <code class="literal"><Alt-C></code></h4></div></div></div><p>
In insert mode, this key is polymorphic as follows:
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
If the previous character is a letter or number, then capitalize it and
enclose it in <code class="literal">\mathcal{}</code>.
</li><li class="listitem">
otherwise insert <code class="literal">\cite{}</code>.
</li></ol></div><p>
In visual mode, it will simply enclose the selection in
<code class="literal">\mathcal{}</code>
</p></div><div class="section" title="3.10.4 <Alt-I>"><div class="titlepage"><div><div><h4 class="title"><a id="Alt-I"></a>3.10.4 <code class="literal"><Alt-I></code></h4></div></div></div><p>
This mapping inserts an <code class="literal">\item</code> command at the
current cursor location depending on which environment the cursor is
enclosed in. The style of the <code class="literal">\item</code> command is
dependent on the enclosing environment. By default,
<code class="literal"><Alt-I></code> has styles defined forthe following
environments:
</p><div class="informaltable"><table border="1"><colgroup><col></col><col></col></colgroup><thead><tr><th>Environment</th><th>Style</th></tr></thead><tbody><tr><td>itemize</td><td>\item </td></tr><tr><td>enumerate</td><td>\item </td></tr><tr><td>theindex</td><td>\item </td></tr><tr><td>thebibliography</td><td>\item[<+biblabel+>]{<+bibkey+>} <++></td></tr><tr><td>description</td><td>\item[<+label+>] <++></td></tr></tbody></table></div><p>
<code class="literal"><Alt-I></code> is intelligent enough to
account for nested environments. For example,
</p><pre class="programlisting">\begin{itemize}
\item first item
\item second item
\begin{description}
\item[label1] first desc
\item[label2] second
% <Alt-I> will insert "\item[<+label+>] <++>" if
% used here
\end{description}
\item third item
% <Alt-I> will insert "\item " when if used here.
\end{itemize}
% <Alt-I> will insert nothing ("") if used here</pre><p>
</p><p>
The style used by <code class="literal"><Alt-I></code> can be customized
using the <a class="link" href="customizing-macros.html#Tex_ItemStyle_environment" title="11.3.13 Tex_ItemStyle_environment"><code class="literal">g:Tex_ItemStyle_environment</code></a>
variable.
