.toc file used to make a table of contents (\. The name itself then consists of either
(a) a string of letters or (b) a single non-letter.

in \item[closing bracket {]}]. Similarly, if an optional
argument comes last, with no required argument after it, then to make
the first character of the following text be an open square bracket,

\text... commands,
is used with an argument, as in \textit{text}. This is
the preferred form. But shown after it, in parenthesis, is the
corresponding declaration form, which is sometimes useful. This form
takes no arguments, as in {\itshape text}. The scope of
the declaration form lasts until the next type style command or the end
of the current group. In addition, each has an environment form such as
\begin{itshape}...\end{itshape}.
\sffamily\bfseries or \bfseries\sffamily.
\nocorrlist, which by default consists of a period and a comma.
To suppress the automatic insertion of italic correction, use
\nocorr at the start or end of the command argument, such as
\textit{\nocorr text} or \textsc{text \nocorr}.
\emph{text} command
is semantic, for text to be emphasized, and should not be used as a
substitute for \textit. For example, \emph{start
text \emph{middle text} end text} will result in the
start text and end text in italics, but middle text
will be in roman.
{\cmd...} instead of
\cmd{...}.
\em command is the unconditional version of \emph.
\mathbf{\mathit{symbol}} does not
create a boldface and italic symbol; instead, it will just be in
italics. This is because typically math symbols need consistent
typographic treatment, regardless of the surrounding environment.
\mathversion{bold} can be used for
switching to bold letters and symbols in
formulas. \mathversion{normal} restores the default.
textcomptextcomp \oldstylenums{numerals} will typeset
so-called &textldquo;old-style&textrdquo; numerals, which have differing heights and
depths (and sometimes widths) from the standard &textldquo;lining&textrdquo; numerals,
which all have the same height as uppercase letters. &latex;&textrsquo;s
default fonts support this, and will respect \textbf (but not
other styles; there are no italic old-style numerals in Computer
Modern). Many other fonts have old-style numerals also; sometimes the
textcomp package must be loaded, and sometimes package options
are provided to make them the default. FAQ entry:

\small lasts until the end of the

command or the end of the current group, so you could enclose it in
extra curly braces {\small We are here, we are here, we are

\part command outputs a part number
such as Part I, alone on its line, in boldface, and in large

then &latex; will skip a page if needed to have the new part on an
odd-numbered page. In report it is again alone on a page, but

searching for a square bracket may get false positives but the word

$$math text$$ from Plain &tex; is sometimes
mistakenly used as a synonym for displaymath. It is not a
synonym, because the displaymath environment checks that it isn&textrsquo;t
started in math mode and that it ends in math mode begun by the matching

different vertical spacing, and because the displaymath

this:

common code: combining vertical space of two adjacent environments;
detecting whether the text following the environment should be
considered a new paragraph or a continuation of the previous one;
adjusting the left and right margins for possible nested list
environments.
trivlist uses the current values of the list
parameters (\parsep is set to the
value of \parskip, and \leftmargin, \labelwidth,

tabbing environment and the more widely-used
tabular environment put text in columns. The most important
distinction is that in tabular the width of columns is
determined automatically by &latex;, while in tabbing the user
sets the tab stops. Another distinction is that tabular
generates a box, but tabbing can be broken across pages.
Finally, while tabular can be used in any mode, tabbing
can be used only in paragraph mode and it starts a new paragraph.
tabbing environment always starts a new paragraph, without
indentation. Moreover, as shown in the example above, there is no need
to use the starred form of the \hspace command at the beginning
of a tabbed row. The right margin of the tabbing environment is
the end of line, so that the width of the environment is
\linewidth.
tabbing environment contains a sequence of tabbed
rows. The first tabbed row begins immediately after
\begin{tabbing} and each row ends with \\ or
\kill. The last row may omit the \\ and end with just
\end{tabbing}.
tabbing environment has a current tab stop
pattern, a sequence of tab stops, numbered 0, 1,
etc. These create n corresponding columns. Tab stop 0 is
always the left margin, defined by the enclosing environment. Tab
stop number i is set if it is assigned a horizontal
position on the page. Tab stop number i can only be set if
all the stops 0, &dots;, have already been set; normally
later stops are to the right of earlier ones.
tabbing environment is typeset
ragged right and left-aligned on the current tab stop. Typesetting is
done in LR mode (tabbing environment.
They are all fragile (\>, \<, \',

array or tabular environment is broken into parts, where

entry. To affect that area, this argument can contain vertical bars
| indicating the placement of vertical rules, and &arobase;{...}
expressions. Thus if cols is |c| then this multicolumn
entry will be centered and a vertical rule will come in the intercolumn
area before it and after it. This table details the exact behavior.
\begin{tabular}{|cc|c|c|}
\multicolumn{1}{r}{w} % entry one
&\multicolumn{1}{|r|}{x} % entry two
&\multicolumn{1}{|r}{y} % entry three
&z % entry four
\end{tabular}
\multicolumn has the cols specifier r with no
initial vertical bar. Between entry one and entry two there will be a
vertical rule; although the first cols does not have an ending
vertical bar, the second cols does have a starting one. Between
entry two and entry three there is a single vertical rule; despite that
the cols in both of the surrounding multicolumn&textrsquo;s call for
a vertical rule, you only get one rule. Between entry three and entry
four there is no vertical rule; the default calls for one but the
cols in the entry three \multicolumn leaves it out, and
that takes precedence. Finally, following entry four there is a
vertical rule because of the default.
tabular definition&textrsquo;s default intercolumn
area specification, including the placement of vertical rules.
tabular definition the first column

overriding the specification to center those two columns on the page
range en-dash.

tabular specification by default puts a vertical
rule between the first and second columns, no such vertical rule appears
in the first row here. That&textrsquo;s because there is no vertical bar in the
cols part of the first row&textrsquo;s first \multicolumn command.
\vlinetabular or array environment
extending the full height and depth of an entry&textrsquo;s row. Can also be
used in an &arobase;-expression, although its synonym vertical
bar | is more common. This command is rarely used in the
body of a table; typically a table&textrsquo;s vertical lines are specified in
tabular&textrsquo;s cols argument and overridden as needed with
\multicolumn (\hfill moves the \vline to the left edge of the
cell. But that is different than putting it halfway between the two
columns, so between the first and second columns there are two vertical
rules, with the one from the {c|cc} specifier coming before the
one produced by the \vline\hfill. In contrast, the first row&textrsquo;s
third entry shows the usual way to put a vertical bar between two
columns. In the second row, the ghi is the widest entry in its
column so in the \vline\hfill the \hfill has no effect and
the vertical line in that entry appears immediately next to the
g, with no whitespace.

\ignorespaces & \ignorespacesafterend\ignorespaces

ignorespaces is often used when defining commands via
\newcommand, or \newenvironment, or \def. The
example below illustrates. It allows a user to show the points values
for quiz questions in the margin but it is inconvenient because, as
shown in the enumerate list, users must not put any space between
the command and the question text.
\newcommand{\points}[1]{\makebox[0pt]{\makebox[10em][l]{#1~pts}}
\begin{enumerate}
\item\points{10}no extra space output here

\fullname will reproduce that.

\honorific{ Mr/Ms} \fullname{Jones} % extra space before title
\end{tabular}
\newcommand{\fullname}[1]{\ignorespaces\&arobase;honorific~#1}.
\ignorespaces is also often used in a \newenvironment
at the end of the begin clause, that is, as part of the second
argument, as in \begin{newenvironment}{env
name}{... \ignorespaces}{...}.
\ignorespacesafterend. An example is that this will show a much
larger vertical space between the first and second environments than
between the second and third.
\newenvironment{eq}{\begin{equation}}{\end{equation}}

\end{eq}
\begin{equation}

\end{equation}
\begin{equation}

\end{equation}
% immediately after the

However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered the rightful property of some one or other of their daughters. ``My dear Mr. Bennet,'' said his lady to him one day, ``have you heard that Netherfield Park is let at last?''

to do. You can use one of the commands: \dotsc if you need the
ellipsis appropriate for a comma following, \dotsb if you need
the ellipses that fits when the dots are followed by a binary operator
or relation symbol, \dotsi for dots with integrals, or
\dotso for others.

\vphantom in this example, the top bars of the two

\textcolor and \color differ in that the first is
a command form, enclosing the text to be colored as an argument. Often
this form is more convenient, or at least more explicit. The second
form is a declaration, as in The moon is made of {\color{green}
green} cheese, so it is in effect until the end of the current group
or environment. This is sometimes useful when writing macros or as
below where it colors everything inside the center environment,
including the vertical and horizontal lines.

\glspl{label} produces the plural
of name (by default it tries adding an s). The third form
capitalizes the first letter of name, as does the fourth form,
which also takes the plural.

letter environment body begins with a required
\opening command such as \opening{Dear Madam or Sir:}.
The letter body text is ordinary &latex; so it can contain
everything from enumerated lists to displayed math, except that commands
such as \chapter that make no sense in a letter are turned off.
Each letter environment body typically ends with a
\closing command such as \closing{Yours,}.
\closing. You can say who
is receiving a copy of the letter with a command like \cc{the
Boss \\ the Boss's Boss}. There&textrsquo;s a similar \encl command for
a list of enclosures. And, you can add a postscript with \ps.

letter environments. If
you just put \makelabels in the preamble then at the end of the
document you will get a sheet with labels for all the recipients, one
for each letter environment, that you can copy to a sheet of peel-off
address labels.
\startlabels,
\mlabel, and \returnaddress (and perhaps \name) in
the preamble. The command \startlabels sets the width, height,
number of columns, etc., of the page onto which the labels are printed.
The command \mlabel{return address}{recipient
address} produces the two labels (or one, if you choose to ignore the
return address) for each letter environment. The first argument,
return address, is the value returned by the macro
\returnaddress. The second argument, recipient address, is
the value passed in the argument to the letter environment. By
default \mlabel ignores the first argument, the return
address, causing the default behavior described in the prior paragraph.
