<p>Everything LaTeX numbers for you has a counter associated with
it. The name of the counter is the same as the name of the
environment or command that produces the number, except with no
<code>\</code>. (enumi - enumiv are used for the nested enumerate
environment.) Below is a list of the counters used in LaTeX's
standard document classes to control numbering.</p>
<pre>
part paragraph figure enumi
chapter subparagraph table enumii
section page footnote enumiii
subsection equation mpfootnote enumiv
subsubsection
</pre>
<ul>
<li><a href="#SEC4">\addtocounter</a>: Add a quantity to a
counter.</li>
<li><a href="#SEC5">\alph</a>: Print value of a counter using
letters.</li>
<li><a href="#SEC6">\arabic</a>: Print value of a counter using
numerals.</li>
<li><a href="#SEC7">\fnsymbol</a>: Print value of a counter using
symbols.</li>
<li><a href="#SEC8">\newcounter</a>: Define a new counter.</li>
<li><a href="#SEC9">\refstepcounter</a>: Add to counter, resetting
subsidiary counters.</li>
<li><a href="#SEC10">\roman</a>: Print value of a counter using
roman numerals.</li>
<li><a href="#SEC12">\setcounter</a>: Set the value of a
counter.</li>
<li><a href="#SEC11">\stepcounter</a>: Add to counter, resetting
subsidiary counters.</li>
<li><a href="#SEC13">\usecounter</a>: Use a specified counter in a
list environment.</li>
<li><a href="#SEC14">\value</a>: Use the value of a counter in an
expression.</li>
</ul>
<h3><a name="SEC4" href="#TOC4">\addtocounter</a></h3>
<p><code>\addtocounter{counter}{value}</code></p>
<p>The <code>\addtocounter</code> command increments the
<code>counter</code> by the amount specified by the
<code>value</code> argument. The <code>value</code> argument can be
negative.</p>
<h3><a name="SEC5" href="#TOC5">\alph</a></h3>
<p><code>\alph{counter}</code></p>
<p>This command causes the value of the <code>counter</code> to be
printed in alphabetic characters. The <code>\alph</code> command
uses lower case alphabetic alphabetic characters, i.e., <code>a, b,
c...</code> while the <code>\Alph</code> command uses upper case
alphabetic characters, i.e., <code>A, B, C...</code>.</p>
<h3><a name="SEC6" href="#TOC6">\arabic</a></h3>
<p><code>\arabic{counter}</code></p>
<p>The <code>\arabic</code> command causes the value of the
<code>counter</code> to be printed in Arabic numbers, i.e.,
<code>3</code>.</p>
<h3><a name="SEC7" href="#TOC7">\fnsymbol</a></h3>
<p><code>\fnsymbol{counter}</code></p>
<p>The <code>\fnsymbol</code> command causes the value of the
<code>counter</code> to be printed in a specific sequence of nine
symbols that can be used for numbering footnotes.</p>
<p>eg. From 1-9:</p>
<p>NB. <code>counter</code> must have a value between 1 and 9
inclusive.</p>
<h3><a name="SEC8" href="#TOC8">\newcounter</a></h3>
<p><code>\newcounter{foo}[counter]</code></p>
<p>The <code>\newcounter</code> command defines a new counter named
<code>foo</code>. The counter is initialized to zero.</p>
<p>The optional argument <code>[counter]</code> causes the counter
<code>foo</code> to be reset whenever the counter named in the
optional argument is incremented.</p>
<h3><a name="SEC9" href="#TOC9">\refstepcounter</a></h3>
<p><code>\refstepcounter{counter}</code></p>
<p>The <code>\refstepcounter</code> command works like
<code>\stepcounter</code> See section <a href=
"#SEC11">\stepcounter</a>, except it also defines the current
<code>\ref</code> value to be the result of
<code>\thecounter</code>.</p>
<h3><a name="SEC10" href="#TOC10">\roman</a></h3>
<p><code>\roman{counter}</code></p>
<p>This command causes the value of the <code>counter</code> to be
printed in Roman numerals. The <code>\roman</code> command uses
lower case Roman numerals, i.e., <code>i, ii, iii...</code>, while
the <code>\Roman</code> command uses upper case Roman numerals,
i.e., <code>I, II, III...</code>.</p>
<h3><a name="SEC11" href="#TOC11">\stepcounter</a></h3>
<p><code>\stepcounter{counter}</code></p>
<p>The <code>\stepcounter</code> command adds one to the
<code>counter</code> and resets all subsidiary counters.</p>
<h3><a name="SEC12" href="#TOC12">\setcounter</a></h3>
<p><code>\setcounter{counter}{value}</code></p>
<p>The <code>\setcounter</code> command sets the value of the
<code>counter</code> to that specified by the <code>value</code>
argument.</p>
<h3><a name="SEC13" href="#TOC13">\usecounter</a></h3>
<p><code>\usecounter{counter}</code></p>
<p>The <code>\usecounter</code> command is used in the second
argument of the <code>list</code> environment to allow the counter
specified to be used to number the list items.</p>
<h3><a name="SEC14" href="#TOC14">\value</a></h3>
<p><code>\value{counter}</code></p>
<p>The <code>\value</code> command produces the value of the
<code>counter</code> named in the mandatory argument. It can be
used where LaTeX expects an integer or number, such as the second
argument of a <code>\setcounter</code> or
<code>\addtocounter</code> command, or in:</p>
<pre>
\hspace{\value{foo}\parindent}
</pre>
<p>It is useful for doing arithmetic with counters.</p>

<p>One reason for numbering things like figures and equations is to
refer the reader to them, as in "See Figure 3 for more
details."</p>
<ul>
<li><a href="#SEC16">\label</a>: Assign a symbolic name to a piece
of text.</li>
<li><a href="#SEC17">\pageref</a>: Refer to a page number.</li>
<li><a href="#SEC18">\ref</a>: Refer to a section, figure or
similar.</li>
</ul>
<h3><a name="SEC16" href="#TOC16">\label</a></h3>
<p><code>\label{key}</code></p>
<p>A <code>\label</code> command appearing in ordinary text assigns
to the <code>key</code> the number of the current sectional unit;
one appearing inside a numbered environment assigns that number to
the <code>key</code>.</p>
<p>A <code>key</code> can consist of any sequence of letters,
digits, or punctuation characters. Upper and lowercase letters are
different.</p>
<p>To avoid accidentally creating two labels with the same name, it
is common to use labels consisting of a prefix and a suffix
separated by a colon. The prefixes conventionally used are</p>
<ul>
<li><code>cha</code> for chapters</li>
<li><code>sec</code> for lower-level sectioning commands</li>
<li><code>fig</code> for figures</li>
<li><code>tab</code> for tables</li>
<li><code>eq</code> for equations</li>
</ul>
<p>Thus, a label for a figure would look like
<code>fig:bandersnatch</code>.</p>
<h3><a name="SEC17" href="#TOC17">\pageref</a></h3>
<p><code>\pageref{key}</code></p>
<p>The <code>\pageref</code> command produces the page number of
the place in the text where the corresponding <code>\label</code>
command appears. ie. where <code>\label{key}</code> appears.</p>
<h3><a name="SEC18" href="#TOC18">\ref</a></h3>
<p><code>\ref{key}</code></p>
<p>The <code>\ref</code> command produces the number of the
sectional unit, equation number, ... of the corresponding
<code>\label</code> command.</p>

<h3><a name="SEC31" href="#TOC31">array</a></h3>
<pre>
\begin{array}{col1col2...coln}
column 1 entry & column 2 entry ... & column n entry \\
.
.
.
\end{array}
</pre>
<p>Math arrays are produced with the array environment. It has a
single mandatory argument describing the number of columns and the
alignment within them. Each column, <code>coln</code>, is specified
by a single letter that tells how items in that row should be
formatted.</p>
<ul>
<li><code>c</code> -- for centred</li>
<li><code>l</code> -- for flush left</li>
<li><code>r</code> -- for flush right</li>
</ul>
<p>Column entries must be separated by an <code>&</code>.
Column entries may include other LaTeX commands. Each row of the
array must be terminated with the string <code>\\</code>.</p>
<p>Note that the <code>array</code> environment can only be used in
math mode, so normally it is used inside an <code>equation</code>
environment.</p>
<h3><a name="SEC32" href="#TOC32">center</a></h3>
<pre>
\begin{center}
Text on line 1 \\
Text on line 2 \\
.
.
.
\end{center}
</pre>
<p>The <code>center</code> environment allows you to create a
paragraph consisting of lines that are centred within the left and
right margins on the current page. Each line must be terminated
with the string <code>\\</code>.</p>
<ul>
<li><a href="#SEC33">\centering</a>: The declaration form of the
<code>center</code> environment.</li>
</ul>
<h4><a name="SEC33" href="#TOC33">\centering</a></h4>
<p>This declaration corresponds to the <code>center</code>
environment. This declaration can be used inside an environment
such as <code>quote</code> or in a <code>parbox</code>. The text of
a figure or table can be centred on the page by putting a
<code>\centering</code> command at the beginning of the figure or
table environment.</p>
<p>Unlike the <code>center</code> environment, the
<code>\centering</code> command does not start a new paragraph; it
simply changes how LaTeX formats paragraph units. To affect a
paragraph unit's format, the scope of the declaration must contain
the blank line or <code>\end</code> command (of an environment like
quote) that ends the paragraph unit.</p>
<h3><a name="SEC34" href="#TOC34">description</a></h3>
<pre>
\begin{description}
\item [label] First item
\item [label] Second item
.
.
.
\end{description}
</pre>
<p>The <code>description</code> environment is used to make
labelled lists. The <code>label</code> is bold face and flushed
right.</p>
<h3><a name="SEC35" href="#TOC35">enumerate</a></h3>
<p><a name="IDX69"></a> <a name="IDX70"></a></p>
<pre>
\begin{enumerate}
\item First item
\item Second item
.
.
.
\end{enumerate}
</pre>
<p>The <code>enumerate</code> environment produces a numbered list.
Enumerations can be nested within one another, up to four levels
deep. They can also be nested within other paragraph-making
environments.</p>
<p>Each item of an enumerated list begins with an
<code>\item</code> command. There must be at least one
<code>\item</code> command within the environment.</p>
<p>The <code>enumerate</code> environment uses the
<code>enumi</code> through <code>enumiv</code> counters (see
section <a href="#SEC3">Counters</a>). The type of numbering can be
changed by redefining <code>\theenumi</code> etc.</p>
<h3><a name="SEC36" href="#TOC36">eqnarray</a></h3>
<p><a name="IDX71"></a> <a name="IDX72"></a> <a name=

<pre>
\begin{eqnarray}
math formula 1 \\
math formula 2 \\
.
.
.
\end{eqnarray}
</pre>
<p>The <code>eqnarray</code> environment is used to display a
sequence of equations or inequalities. It is very much like a
three-column <code>array</code> environment, with consecutive rows
separated by <code>\\</code> and consecutive items within a row
separated by an <code>&</code>.</p>
<p>An equation number is placed on every line unless that line has
a <code>\nonumber</code> command.</p>
<p>The command <code><a name="IDX74">\lefteqn</a></code> is used
for splitting long formulas across lines. It typesets its argument
in display style flush left in a box of zero width.</p>
<h3><a name="SEC37" href="#TOC37">equation</a></h3>
<p><a name="IDX75"></a> <a name="IDX76"></a> <a name=
"IDX77"></a></p>
<pre>
\begin{equation}
math formula
\end{equation}
</pre>
<p>The <code>equation</code> environment centres your equation on
the page and places the equation number in the right margin.</p>
<h3><a name="SEC38" href="#TOC38">figure</a></h3>
<p><a name="IDX78"></a> <a name="IDX79"></a></p>
<pre>
\begin{figure}[placement]
body of the figure
<a name="IDX80">\caption{figure title}</a>
\end{figure}
</pre>
<p>Figures are objects that are not part of the normal text, and
are usually "floated" to a convenient place, like the top of a
page. Figures will not be split between two pages.</p>
<p>The optional argument <code>[placement]</code> determines where
LaTeX will try to place your figure. There are four places where
LaTeX can possibly put a float:</p>
<ol>
<li><code>h</code> (Here) - at the position in the text where the
figure environment appears.</li>
<li><code>t</code> (Top) - at the top of a text page.</li>
<li><code>b</code> (Bottom) - at the bottom of a text page.</li>
<li><code>p</code> (Page of floats) - on a separate float page,
which is a page containing no text, only floats.</li>
</ol>
<p>The standard report and article classes use the default
placement <code>tbp</code>.</p>
<p>The body of the figure is made up of whatever text, LaTeX
commands, etc. you wish. The <code>\caption</code> command allows
you to title your figure.</p>
<h3><a name="SEC39" href="#TOC39">flushleft</a></h3>
<p><a name="IDX81"></a> <a name="IDX82"></a> <a name=
"IDX83"></a></p>
<pre>
\begin{flushleft}
Text on line 1 \\
Text on line 2 \\
.
.
.
\end{flushleft}
</pre>
<p>The <code>flushleft</code> environment allows you to create a
paragraph consisting of lines that are flushed left, to the
left-hand margin. Each line must be terminated with the string
<code>\\</code>.</p>
<ul>
<li><a href="#SEC40">\raggedright</a>: The declaration form of the
<code>flushleft</code> environment.</li>
</ul>
<h4><a name="SEC40" href="#TOC40">\raggedright</a></h4>
<p><a name="IDX84"></a> <a name="IDX85"></a> <a name="IDX86"></a>
<a name="IDX87"></a></p>
<p>This declaration corresponds to the <code>flushleft</code>
environment. This declaration can be used inside an environment
such as <code>quote</code> or in a <code>parbox</code>.</p>
<p>Unlike the <code>flushleft</code> environment, the
<code>\raggedright</code> command does not start a new paragraph;
it simply changes how LaTeX formats paragraph units. To affect a
paragraph unit's format, the scope of the declaration must contain
the blank line or <code>\end</code> command (of an environment like
quote) that ends the paragraph unit.</p>
<h3><a name="SEC41" href="#TOC41">flushright</a></h3>
<p><a name="IDX88"></a> <a name="IDX89"></a> <a name=

<pre>
\begin{flushright}
Text on line 1 \\
Text on line 2 \\
.
.

\end{flushright}
</pre>
<p>The <code>flushright</code> environment allows you to create a
paragraph consisting of lines that are flushed right, to the
right-hand margin. Each line must be terminated with the string
<code>\\</code>.</p>
<ul>
<li><a href="#SEC42">\raggedleft</a>: The declaration form of the
<code>flushright</code> environment.</li>
</ul>
<h4><a name="SEC42" href="#TOC42">\raggedleft</a></h4>
<p><a name="IDX91"></a> <a name="IDX92"></a> <a name="IDX93"></a>
<a name="IDX94"></a></p>
<p>This declaration corresponds to the <code>flushright</code>
environment. This declaration can be used inside an environment
such as <code>quote</code> or in a <code>parbox</code>.</p>
<p>Unlike the <code>flushright</code> environment, the
<code>\raggedleft</code> command does not start a new paragraph; it
simply changes how LaTeX formats paragraph units. To affect a
paragraph unit's format, the scope of the declaration must contain
the blank line or <code>\end</code> command (of an environment like
quote) that ends the paragraph unit.</p>
<h3><a name="SEC43" href="#TOC43">itemize</a></h3>
<p><a name="IDX95"></a> <a name="IDX96"></a> <a name=
"IDX97"></a></p>
<pre>
\begin{itemize}
\item First item
\item Second item
.
.
.
\end{itemize}
</pre>
<p>The <code>itemize</code> environment produces a "bulleted" list.
Itemizations can be nested within one another, up to four levels
deep. They can also be nested within other paragraph-making
environments.</p>
<p>Each item of an <code>itemized</code> list begins with an
<code>\item</code> command. There must be at least one
<code>\item</code> command within the environment.</p>
<p>The <code>itemize</code> environment uses the <code>itemi</code>
through <code>itemiv</code> counters (see section <a href=
"#SEC3">Counters</a>). The type of numbering can be changed by
redefining <code>\theitemi</code> etc.</p>
<h3><a name="SEC44" href="#TOC44">letter</a></h3>
<p><a name="IDX98"></a></p>
<p>This environment is used for creating letters. See section
<a href="#SEC91">Letters</a>.</p>
<h3><a name="SEC45" href="#TOC45">list</a></h3>
<p><a name="IDX99"></a> <a name="IDX100"></a></p>
<p>The <code>list</code> environment is a generic environment which
is used for defining many of the more specific environments. It is
seldom used in documents, but often in macros.</p>
<pre>
\begin{list}{label}{spacing}
\item First item
\item Second item
.
.
.
\end{list}
</pre>
<p>The <code>{label}</code> argument specifies how items should be
labelled. This argument is a piece of text that is inserted in a
box to form the label. This argument can and usually does contain
other LaTeX commands.</p>
<p>The <code>{spacing}</code> argument contains commands to change
the spacing parameters for the list. This argument will most often
be null, i.e., <code>{}</code>. This will select all default
spacing which should suffice for most cases.</p>
<h3><a name="SEC46" href="#TOC46">minipage</a></h3>
<p><a name="IDX101"></a> <a name="IDX102"></a> <a name=
"IDX103"></a> <a name="IDX104"></a></p>
<pre>
\begin{minipage}[position]{width}
text
\end{minipage}
</pre>
<p>The <code>minipage</code> environment is similar to a
<code>\parbox</code> command. It takes the same optional
<code>position</code> argument and mandatory <code>width</code>
argument. You may use other paragraph-making environments inside a
minipage.</p>
<p>Footnotes in a <code>minipage</code> environment are handled in
a way that is particularly useful for putting footnotes in figures
or tables. A <code>\footnote</code> or <code>\footnotetext</code>
command puts the footnote at the bottom of the minipage instead of
at the bottom of the page, and it uses the <code>mpfootnote</code>
counter instead of the ordinary <code>footnote</code> counter See
section <a href="#SEC3">Counters</a>.</p>
<p>NOTE: Don't put one minipage inside another if you are using
footnotes; they may wind up at the bottom of the wrong
minipage.</p>
<h3><a name="SEC47" href="#TOC47">picture</a></h3>
<p><a name="IDX105"></a> <a name="IDX106"></a> <a name=
"IDX107"></a></p>
<pre>
\begin{picture}(width,height)(x offset,y offset)
.
.
picture commands
.
.
\end{picture}
</pre>
<p>The <code>picture</code> environment allows you to create just
about any kind of picture you want containing text, lines, arrows
and circles. You tell LaTeX where to put things in the picture by
specifying their coordinates. A coordinate is a number that may
have a decimal point and a minus sign -- a number like
<code>5</code>, <code>2.3</code> or <code>-3.1416</code>. A
coordinate specifies a length in multiples of the unit length
<code>\unitlength</code>, so if <code>\unitlength</code> has been
set to <code>1cm</code>, then the coordinate 2.54 specifies a
length of 2.54 centimetres. You can change the value of
<code>\unitlength</code> anywhere you want, using the
<code>\setlength</code> command, but strange things will happen if
you try changing it inside the picture environment.</p>
<p>A position is a pair of coordinates, such as
<code>(2.4,-5)</code>, specifying the point with x-coordinate
<code>2.4</code> and y-coordinate <code>-5</code>. Coordinates are
specified in the usual way with respect to an origin, which is
normally at the lower-left corner of the picture. Note that when a
position appears as an argument, it is not enclosed in braces; the
parentheses serve to delimit the argument.</p>
<p>The <code>picture</code> environment has one mandatory argument,
which is a <code>position</code>. It specifies the size of the
picture. The environment produces a rectangular box with width and
height determined by this argument's x- and y-coordinates.</p>
<p>The <code>picture</code> environment also has an optional
<code>position</code> argument, following the <code>size</code>
argument, that can change the origin. (Unlike ordinary optional
arguments, this argument is not contained in square brackets.) The
optional argument gives the coordinates of the point at the
lower-left corner of the picture (thereby determining the origin).
For example, if <code>\unitlength</code> has been set to
<code>1mm</code>, the command</p>
<pre>
\begin{picture}(100,200)(10,20)
</pre>
<p>produces a picture of width 100 millimeters and height 200
millimeters, whose lower-left corner is the point (10,20) and whose
upper-right corner is therefore the point (110,220). When you first
draw a picture, you will omit the optional argument, leaving the
origin at the lower-left corner. If you then want to modify your
picture by shifting everything, you just add the appropriate
optional argument.</p>
<p>The environment's mandatory argument determines the nominal size
of the picture. This need bear no relation to how large the picture
really is; LaTeX will happily allow you to put things outside the
picture, or even off the page. The picture's nominal size is used
by LaTeX in determining how much room to leave for it.</p>
<p>Everything that appears in a picture is drawn by the
<code>\put</code> command. The command</p>
<pre>
\put (11.3,-.3){...}
</pre>
<p>puts the object specified by <code>...</code> in the picture,
with its reference point at coordinates (11.3,-.3). The reference
points for various objects will be described below.</p>
<p>The <code>\put</code> command creates an <strong>LR
box</strong>. You can put anything in the text argument of the
<code>\put</code> command that you'd put into the argument of an
<code>\mbox</code> and related commands. When you do this, the
reference point will be the lower left corner of the box.</p>
<p>Picture commands:</p>
<ul>
<li><a href="#SEC48">\circle</a>: Draw a circle.</li>
<li><a href="#SEC49">\dashbox</a>: Draw a dashed box.</li>
<li><a href="#SEC50">\frame</a>: Draw a frame around an
object.</li>
<li><a href="#SEC51">\framebox (picture)</a>: Draw a box with a
frame around it.</li>
<li><a href="#SEC52">\line</a>: Draw a straight line.</li>
<li><a href="#SEC53">\linethickness</a>: Set the line
thickness.</li>
<li><a href="#SEC54">\makebox (picture)</a>: Draw a box of the
specified size.</li>
<li><a href="#SEC55">\multiput</a>: Draw multiple instances of an
object.</li>
<li><a href="#SEC56">\oval</a>: Draw an ellipse.</li>
<li><a href="#SEC57">\put</a>: Place an object at a specified
place.</li>
<li><a href="#SEC58">\shortstack</a>: Make a pile of objects.</li>
<li><a href="#SEC59">\vector</a>: Draw a line with an arrow.</li>
</ul>
<h4><a name="SEC48" href="#TOC48">\circle</a></h4>
<p><a name="IDX108"></a></p>
<p><code>\circle[*]{diameter}</code></p>
<p>The <code>\circle</code> command produces a circle with a
diameter as close to the specified one as possible. If the
<code>*</code>-form of the command is used, LaTeX draws a solid
circle.</p>
<p>Note that only circles up to 40 pt can be drawn.</p>
<h4><a name="SEC49" href="#TOC49">\dashbox</a></h4>
<p><a name="IDX109"></a></p>
<p>Draws a box with a dashed line.</p>
<p><code>\dashbox{dash_length}(width,height){...}</code></p>
<p>The <code>\dashbox</code> has an extra argument which specifies
the width of each dash. A dashed box looks best when the
<code>width</code> and <code>height</code> are multiples of the
<code>dash_length</code>.</p>
<h4><a name="SEC50" href="#TOC50">\frame</a></h4>
<p><a name="IDX110"></a></p>
<p><code>\frame{...}</code></p>
<p>The <code>\frame</code> command puts a rectangular frame around
the object specified in the argument. The reference point is the
bottom left corner of the frame. No extra space is put between the
frame and the object.</p>
<h4><a name="SEC51" href="#TOC51">\framebox</a></h4>
<p><a name="IDX111"></a></p>
<p><code>\framebox(width,height)[position]{...}</code></p>
<p>The <code>\framebox</code> command is exactly the same as the
<code>\makebox</code> command, except that it puts a frame around
the outside of the box that it creates.</p>
<p>The <code>framebox</code> command produces a rule of thickness
<code>\fboxrule</code>, and leaves a space <code>\fboxsep</code>
between the rule and the contents of the box.</p>
<h4><a name="SEC52" href="#TOC52">\line</a></h4>
<p><a name="IDX112"></a></p>
<p><code>\line(x slope,y slope){length}</code></p>
<p>The <code>\line</code> command draws a line of the specified
<code>length</code> and <code>slope</code>.</p>
<p>Note that LaTeX can only draw lines with slope = x/y, where x
and y have integer values from -6 through 6.</p>
<h4><a name="SEC53" href="#TOC53">\linethickness</a></h4>
<p><a name="IDX113"></a></p>
<p><code>\linethickness{dimension}</code></p>
<p>Declares the thickness of horizontal and vertical lines in a
picture environment to be <code>dimension</code>, which must be a
positive length. It does not affect the thickness of slanted lines
and circles, or the quarter circles drawn by <code>\oval</code> to
form the corners of an oval.</p>
<h4><a name="SEC54" href="#TOC54">\makebox</a></h4>
<p><a name="IDX114"></a></p>
<p><code>\makebox(width,height)[position]{...}</code></p>
<p>The <code>\makebox</code> command for the picture environment is
similar to the normal <code>\makebox</code> command except that you
must specify a <code>width</code> and <code>height</code> in
multiples of <code>\unitlength</code>.</p>
<p>The optional argument, <code>[position]</code>, specifies the
quadrant that your text appears in. You may select up to two of the
following:</p>
<ul>
<li><code>t</code> - Moves the item to the top of the
rectangle</li>
<li><code>b</code> - Moves the item to the bottom</li>
<li><code>l</code> - Moves the item to the left</li>
<li><code>r</code> - Moves the item to the right</li>

<p><a name="IDX115"></a></p>
<p><code>\multiput(x coord,y coord)(delta x,delta y){number of
copies}{object}</code></p>
<p>The <code>\multiput</code> command can be used when you are
putting the same object in a regular pattern across a picture.</p>
<h4><a name="SEC56" href="#TOC56">\oval</a></h4>
<p><a name="IDX116"></a></p>
<p><code>\oval(width,height)[portion]</code></p>
<p>The <code>\oval</code> command produces a rectangle with rounded
corners. The optional argument, <code>[portion]</code>, allows you
to select part of the oval.</p>
<ul>
<li><code>t</code> - Selects the top portion</li>
<li><code>b</code> - Selects the bottom portion</li>
<li><code>r</code> - Selects the right portion</li>
<li><code>l</code> - Selects the left portion</li>
</ul>
<p>Note that the "corners" of the oval are made with quarter
circles with a maximum radius of 20 pt, so large "ovals" will look
more like boxes with rounded corners.</p>
<h4><a name="SEC57" href="#TOC57">\put</a></h4>
<p><a name="IDX117"></a></p>
<p><code>\put(x coord,y coord){ ... }</code></p>

<p><a name="IDX118"></a></p>
<p><code>\shortstack[position]{... \\ ... \\ ...}</code></p>
<p>The <code>\shortstack</code> command produces a stack of
objects. The valid positions are:</p>
<ul>
<li><code>r</code> - Moves the objects to the right of the
stack</li>
<li><code>l</code> - Moves the objects to the left of the
stack</li>
<li><code>c</code> - Moves the objects to the center of the stack
(default)</li>
</ul>

</pre>
<p>The <code>tabbing</code> environment provides a way to align
text in columns. It works by setting tab stops and tabbing to them
much the way you do with an ordinary typewriter.</p>
<p>It is best suited for cases where the width of each column is
constant and known in advance.</p>
<p>This environment can be broken across pages, unlike the
<code>tabular</code> environment.</p>
<p>The following commands can be used inside a <code>tabbing</code>
environment:</p>
<dl>
<dt><code><a name="IDX129">\=</a></code></dt>
<dd>Sets a tab stop at the current position.</dd>
<dt><code><a name="IDX130">\></a></code></dt>
<dd>Advances to the next tab stop.</dd>
<dt><code><a name="IDX131">\<</a></code></dt>
<dd>This command allows you to put something to the left of the
local margin without changing the margin. Can only be used at the
start of the line.</dd>
<dt><code><a name="IDX132">\+</a></code></dt>
<dd>Moves the left margin of the next and all the following
commands one tab stop to the right.</dd>
<dt><code><a name="IDX133">\-</a></code></dt>
<dd>Moves the left margin of the next and all the following
commands one tab stop to the left.</dd>
<dt><code><a name="IDX134">\'</a></code></dt>
<dd>Moves everything that you have typed so far in the current
column, i.e. everything from the most recent <code>\></code>,
<code>\<</code>, <code>\'</code>, <code>\\</code>, or
<code>\kill</code> command, to the right of the previous column,
flush against the current column's tab stop.</dd>
<dt><code><a name="IDX135">\`</a></code></dt>
<dd>Allows you to put text flush right against any tab stop,
including tab stop 0. However, it can't move text to the right of
the last column because there's no tab stop there. The
<code>\`</code> command moves all the text that follows it, up to
the <code>\\</code> or <code>\end{tabbing}</code> command that ends
the line, to the right margin of the tabbing environment. There
must be no <code>\></code> or <code>\'</code> command between
the <code>\`</code> and the command that ends the line.</dd>
<dt><code><a name="IDX136">\kill</a></code></dt>
<dd>Sets tab stops without producing text. Works just like
<code>\\</code> except that it throws away the current line instead
of producing output for it. The effect of any <code>\=</code>,
<code>\+</code> or <code>\-</code> commands in that line remain in
effect.</dd>
<dt><code><a name="IDX137">\pushtabs</a></code></dt>
<dd>Saves all current tab stop positions. Useful for temporarily
changing tab stop positions in the middle of a <code>tabbing</code>
environment.</dd>
<dt><code><a name="IDX138">\pushtabs</a></code></dt>
<dd>Restores the tab stop positions saved by the last
<code>\pushtabs</code>.</dd>
<dt><code><a name="IDX139">\a</a></code></dt>
<dd>In a <code>tabbing</code> environment, the commands
<code>\=</code>, <code>\'</code> and <code>\`</code> do not produce
accents as normal. Instead, the commands <code>\a=</code>,
<code>\a'</code> and <code>\a`</code> are used.</dd>
</dl>
<p>This example typesets a Pascal function in a traditional
format:</p>
<pre>
\begin{tabbing}
function \= fact(n : integer) : integer;\\
\> begin \= \+ \\
\> if \= n $>$ 1 then \+ \\
fact := n * fact(n-1) \- \\
else \+ \\
fact := 1; \-\- \\
end;\\

<pre>
\begin{table}[placement]
body of the table
\caption{table title}
\end{table}
</pre>
<p>Tables are objects that are not part of the normal text, and are
usually "floated" to a convenient place, like the top of a page.
Tables will not be split between two pages.</p>
<p>The optional argument <code>[placement]</code> determines where
LaTeX will try to place your table. There are four places where
LaTeX can possibly put a float:</p>
<ul>
<li><code>h</code> : Here - at the position in the text where the
table environment appears.</li>
<li><code>t</code> : Top - at the top of a text page.</li>
<li><code>b</code> : Bottom - at the bottom of a text page.</li>
<li><code>p</code> : Page of floats - on a separate float page,
which is a page containing no text, only floats.</li>
</ul>
<p>The standard <code>report</code> and <code>article</code>
classes use the default placement <code>[tbp]</code>.</p>
<p>The body of the table is made up of whatever text, LaTeX
commands, etc., you wish. The <code>\caption</code> command allows
you to title your table.</p>
<h3><a name="SEC64" href="#TOC64">tabular</a></h3>
<p><a name="IDX143"></a> <a name="IDX144"></a> <a name=
"IDX145"></a></p>
<pre>
\begin{tabular}[pos]{cols}
column 1 entry & column 2 entry ... & column n entry \\
.
.

\end{tabular}
</pre>
<p>or</p>
<pre>
\begin{tabular*}{width}[pos]{cols}
column 1 entry & column 2 entry ... & column n entry \\
.
.
.
\end{tabular*}
</pre>
<p>These environments produce a box consisting of a sequence of
rows of items, aligned vertically in columns. The mandatory and
optional arguments consist of:</p>
<dl>
<dt><code>width</code></dt>
<dd>Specifies the width of the <code>tabular*</code> environment.
There must be rubber space between columns that can stretch to fill
out the specified width.</dd>
<dt><code>pos</code></dt>
<dd>Specifies the vertical position; default is alignment on the
center of the environment.
<ul>
<li><code>t</code> - align on top row</li>
<li><code>b</code> - align on bottom row</li>
</ul>
</dd>
<dt><code>cols</code></dt>
<dd>Specifies the column formatting. It consists of a sequence of
the following specifiers, corresponding to the sequence of columns
and intercolumn material.
<ul>
<li><code>l</code> - A column of left-aligned items.</li>
<li><code>r</code> - A column of right-aligned items.</li>
<li><code>c</code> - A column of centred items.</li>
<li><code>|</code> - A vertical line the full height and depth of
the environment.</li>
<li><code>@{text}</code> - This inserts <code>text</code> in every
row. An @-expression suppresses the intercolumn space normally
inserted between columns; any desired space between the inserted
text and the adjacent items must be included in text. An
<code>\extracolsep{wd}</code> command in an @-expression causes an
extra space of width <code>wd</code> to appear to the left of all
subsequent columns, until countermanded by another
<code>\extracolsep</code> command. Unlike ordinary intercolumn
space, this extra space is not suppressed by an @-expression. An
<code>\extracolsep</code> command can be used only in an
@-expression in the <code>cols</code> argument.</li>
<li><code>p{wd}</code> - Produces a column with each item typeset
in a parbox of width <code>wd</code>, as if it were the argument of
a <code>\parbox[t]{wd}</code> command. However, a <code>\\</code>
may not appear in the item, except in the following situations:
<ol>
<li>inside an environment like <code>minipage</code>,
<code>array</code>, or <code>tabular</code>.</li>
<li>inside an explicit <code>\parbox</code>.</li>
<li>in the scope of a <code>\centering</code>,
<code>\raggedright</code>, or <code>\raggedleft</code> declaration.
The latter declarations must appear inside braces or an environment
when used in a <code>p</code>-column element.</li>
</ol>
</li>
<li><code>*{num}{cols}</code> - Equivalent to <code>num</code>
copies of <code>cols</code>, where <code>num</code> is any positive
integer and <code>cols</code> is any list of column-specifiers,
which may contain another <code>*-expression</code>.</li>
</ul>
</dd>
</dl>
<p>These commands can be used inside a <code>tabular</code>
environment:</p>
<ul>
<li><a href="#SEC65">\cline</a>: Draw a horizontal line spanning
some columns.</li>
<li><a href="#SEC66">\hline</a>: Draw a horizontal line spanning
all columns.</li>
<li><a href="#SEC67">\multicolumn</a>: Make an item spanning
several columns.</li>
<li><a href="#SEC68">\vline</a>: Draw a vertical line.</li>
</ul>
<h4><a name="SEC65" href="#TOC65">\cline</a></h4>
<p><a name="IDX146"></a></p>
<p><code>\cline{i-j}</code></p>
<p>The <code>\cline</code> command draws horizontal lines across
the columns specified, beginning in column <code>i</code> and
ending in column <code>j</code>, which are identified in the
mandatory argument.</p>
<h4><a name="SEC66" href="#TOC66">\hline</a></h4>
<p><a name="IDX147"></a></p>
<p>The <code>\hline</code> command will draw a horizontal line the
width of the table. It's most commonly used to draw a line at the
top, bottom, and between the rows of the table.</p>
<h4><a name="SEC67" href="#TOC67">\multicolumn</a></h4>
<p><a name="IDX148"></a></p>
<p><code>\multicolumn{cols}{pos}{text}</code></p>
<p>The <code>\multicolumn</code> is used to make an entry that
spans several columns. The first mandatory argument,
<code>cols</code>, specifies the number of columns to span. The
second mandatory argument, <code>pos</code>, specifies the
formatting of the entry; <code>c</code> for centred, <code>l</code>
for flushleft, <code>r</code> for flushright. The third mandatory
argument, <code>text</code>, specifies what text is to make up the
entry.</p>
<h4><a name="SEC68" href="#TOC68">\vline</a></h4>
<p><a name="IDX149"></a></p>
<p>The <code>\vline</code> command will draw a vertical line
extending the full height and depth of its row. An
<code>\hfill</code> command can be used to move the line to the
edge of the column. It can also be used in an @-expression.</p>
<h3><a name="SEC69" href="#TOC69">thebibliography</a></h3>

<pre>
\begin{thebibliography}{widest-label}
\bibitem[label]{cite_key}
.
.
.
\end{thebibliography}
</pre>
<p>The <code>thebibliography</code> environment produces a
bibliography or reference list. In the <code>article</code> class,
this reference list is labelled "References"; in the
<code>report</code> class, it is labelled "Bibliography".</p>
<ul>
<li><code>widest-label</code>: Text that, when printed, is
approximately as wide as the widest item label produces by the
<code>\bibitem</code> commands.</li>
</ul>
<ul>
<li><a href="#SEC70">\bibitem</a>: Specify a bibliography
item.</li>
<li><a href="#SEC71">\cite</a>: Refer to a bibliography item.</li>
<li><a href="#SEC72">\nocite</a>: Include an item in the
bibliography.</li>
<li><a href="#SEC73">Using BibTeX</a>: Automatic generation of
bibliographies.</li>
</ul>
<h4><a name="SEC70" href="#TOC70">\bibitem</a></h4>
<p><a name="IDX152"></a></p>
<p><code>\bibitem[label]{cite_key}</code></p>
<p>The <code>\bibitem</code> command generates an entry labelled by
<code>label</code>. If the <code>label</code> argument is missing,
a number is generated as the <code>label</code>, using the
<code>enumi</code> counter. The <code>cite_key</code> is any
sequence of letters, numbers, and punctuation symbols not
containing a comma. This command writes an entry on the
<tt>`.aux'</tt> file containing <code>cite_key</code> and the
item's <code>label</code>. When this <tt>`.aux'</tt> file is read
by the <code>\begin{document}</code> command, the item's
<code>label</code> is associated with <code>cite_key</code>,
causing the reference to <code>cite_key</code> by a
<code>\cite</code> command to produce the associated
<code>label</code>.</p>
<h4><a name="SEC71" href="#TOC71">\cite</a></h4>
<p><a name="IDX153"></a></p>
<p><code>\cite[text]{key_list}</code></p>
<p>The <code>key_list</code> argument is a list of citation keys.
This command generates an in-text citation to the references
associated with the keys in <code>key_list</code> by entries on the
<tt>`.aux'</tt> file read by the <code>\begin{document}</code>
command.</p>
<p>The optional <code>text</code> argument will appear after the
citation, i.e. <code>\cite[p. 2]{knuth}</code> might produce
`[Knuth, p. 2]'.</p>
<h4><a name="SEC72" href="#TOC72">\nocite</a></h4>
<p><a name="IDX154"></a></p>
<p><code>\nocite{key_list}</code></p>
<p>The <code>\nocite</code> command produces no text, but writes
<code>key_list</code>, which is a list of one or more citation
keys, on the <tt>`.aux'</tt> file.</p>
<h4><a name="SEC73" href="#TOC73">Using BibTeX</a></h4>

<p>If you use the BibTeX program by Oren Patashnik (highly
recommended if you need a bibliography of more than a couple of
titles) to maintain your bibliography, you don't use the
<code>thebibliography</code> environment. Instead, you include the
lines</p>
<pre>
\bibliographystyle{style}
\bibliography{bibfile}
</pre>
<p>where <code>style</code> refers to a file
<code>style.bst</code>, which defines how your citations will look.
The standard styles distributed with BibTeX are:</p>
<dl>
<dt><code>alpha</code></dt>
<dd>Sorted alphabetically. Labels are formed from name of author
and year of publication.</dd>
<dt><code>plain</code></dt>
<dd>Sorted alphabetically. Labels are numeric.</dd>
<dt><code>unsrt</code></dt>
<dd>Like <code>plain</code>, but entries are in order of
citation.</dd>
<dt><code>abbrv</code></dt>
<dd>Like <code>plain</code>, but more compact labels.</dd>
</dl>
<p>In addition, numerous other BibTeX style files exist tailored to
the demands of various publications.</p>
<p>The argument to <code>\bibliography</code> refers to the file
<code>bibfile.bib</code>, which should contain your database in
BibTeX format. Only the entries referred to via <code>\cite</code>
and <code>\nocite</code> will be listed in the bibliography.</p>
<h3><a name="SEC74" href="#TOC74">theorem</a></h3>
<p><a name="IDX160"></a> <a name="IDX161"></a></p>
<pre>
\begin{theorem}

<pre>
\begin{titlepage}
text
\end{titlepage}
</pre>
<p>The <code>titlepage</code> environment creates a title page,
i.e. a page with no printed page number or heading. It also causes
the following page to be numbered page one. Formatting the title
page is left to you. The <code><a name="IDX165">\today</a></code>
command comes in handy for title pages.</p>
<p>Note that you can use the <code>\maketitle</code> (see section
<a href="#SEC132">\maketitle</a>) command to produce a standard
title page.</p>

<p><code>\verb char literal_text char</code></p>
<p><code>\verb*char literal_text char</code></p>
<p>Typesets <code>literal_text</code> exactly as typed, including
special characters and spaces, using a typewriter
(<code>\tt</code>) type style. There may be no space between
<code>\verb</code> or <code>\verb*</code> and <code>char</code>
(space is shown here only for clarity). The <code>*-form</code>
differs only in that spaces are printed as `\verb*| |'.</p>

</pre>
<p>The <code>verse</code> environment is designed for poetry,
though you may find other uses for it.</p>
<p>The margins are indented on the left and the right. Separate the
lines of each stanza with <code>\\</code>, and use one or more
blank lines to separate the stanzas.</p>

<p>Footnotes can be produced in one of two ways. They can be
produced with one command, the <code>\footnote</code> command. They
can also be produced with two commands, the
<code>\footnotemark</code> and the <code>\footnotetext</code>
commands. See the specific command for information on why you would
use one over the other.</p>
<ul>
<li><a href="#SEC80">\footnote</a>: Insert a footnote.</li>

</ul>
<h3><a name="SEC80" href="#TOC80">\footnote</a></h3>
<p><a name="IDX176"></a></p>
<p><code>\footnote[number]{text}</code></p>
<p>The <code>\footnote</code> command places the numbered footnote
<code>text</code> at the bottom of the current page. The optional
argument, <code>number</code>, is used to change the default
footnote number. This command can only be used in outer paragraph
mode; i.e., you cannot use it in sectioning commands like
<code>\chapter</code>, in figures, tables or in a
<code>tabular</code> environment.</p>
<h3><a name="SEC81" href="#TOC81">\footnotemark</a></h3>
<p><a name="IDX177"></a></p>
<p>The <code>\footnotemark</code> command puts the footnote
<code>number</code> in the text. This command can be used in inner
paragraph mode. The text of the footnote is supplied by the
<code>\footnotetext</code> command.</p>
<p>This command can be used to produce several consecutive footnote
markers referring to the same footnote by using</p>
<p><code>\footnotemark[\value{footnote}]</code></p>
<p>after the first <code>\footnote</code> command.</p>
<h3><a name="SEC82" href="#TOC82">\footnotetext</a></h3>
<p><a name="IDX178"></a></p>
<p><code>\footnotetext[number]{text}</code></p>
<p>The <code>\footnotetext</code> command produces the
<code>text</code> to be placed at the bottom of the page. This
command can come anywhere after the <code>\footnotemark</code>
command. The <code>\footnotetext</code> command must appear in
outer paragraph mode.</p>
<p>The optional argument, <code>number</code>, is used to change
the default footnote number.</p>

<p><a name="IDX180"></a> <a name="IDX181"></a></p>
<p><code>\newlength{\gnat}</code></p>
<p>The <code>\newlength</code> command defines the mandatory
argument, <code>\gnat</code>, as a <code>length</code> command with
a value of <code>0in</code>. An error occurs if a
<code>\gnat</code> command already exists.</p>
<h3><a name="SEC85" href="#TOC85">\setlength</a></h3>
<p><a name="IDX182"></a> <a name="IDX183"></a></p>
<p><code>\setlength{\gnat}{length}</code></p>
<p>The <code>\setlength</code> command is used to set the value of
a <code>length</code> command. The <code>length</code> argument can
be expressed in any terms of length LaTeX understands, i.e., inches
(<code>in</code>), millimeters (<code>mm</code>), points
(<code>pt</code>), etc.</p>
<h3><a name="SEC86" href="#TOC86">\addtolength</a></h3>
<p><a name="IDX184"></a> <a name="IDX185"></a></p>
<p><code>\addtolength{\gnat}{length}</code></p>
<p>The <code>\addtolength</code> command increments a "length

argument. It can be a negative amount.</p>
<h3><a name="SEC87" href="#TOC87">\settodepth</a></h3>
<p><a name="IDX186"></a></p>
<p><code>\settodepth{\gnat}{text}</code></p>
<p>The <code>\settodepth</code> command sets the value of a

<p>You can use LaTeX to typeset letters, both personal and
business. The <code>letter</code> document class is designed to
make a number of letters at once, although you can make just one if
you so desire.</p>
<p>Your <tt>`.tex'</tt> source file has the same minimum commands
as the other document classes, i.e., you must have the following
commands as a minimum:</p>
<pre>
\documentclass{letter}
\begin{document}
... letters ...
\end{document}
</pre>
<p>Each letter is a <code>letter</code> environment, whose argument
is the name and address of the recipient. For example, you might
have:</p>
<pre>
\begin{letter}{Mr. Joe Smith\\ 2345 Princess St.
\\ Edinburgh, EH1 1AA}
...
\end{letter}
</pre>
<p>The letter itself begins with the <code>\opening</code> command.
The text of the letter follows. It is typed as ordinary LaTeX
input. Commands that make no sense in a letter, like
<code>\chapter</code>, do not work. The letter closes with a
<code>\closing</code> command.</p>
<p>After the <code>closing</code>, you can have additional
material. The <code>\cc</code> command produces the usual "cc:
...". There's also a similar <code>\encl</code> command for a list
of enclosures. With both these commands, use <code>\\</code> to
separate the items.</p>
<p>These commands are used with the <code>letter</code> class:</p>
<ul>
<li><a href="#SEC92">\address</a>: Your return address.</li>
<li><a href="#SEC93">\cc</a>: Cc list.</li>
<li><a href="#SEC94">\closing</a>: Saying goodbye.</li>
<li><a href="#SEC95">\encl</a>: List of enclosed material.</li>
<li><a href="#SEC96">\location</a>: Your organization's

<li><a href="#SEC97">\makelabels</a>: Making address labels.</li>
<li><a href="#SEC98">\name</a>: Your name, for the return
address.</li>
<li><a href="#SEC99">\opening</a>: Saying hello.</li>
<li><a href="#SEC100">\ps</a>: Adding a postscript.</li>

<li><a href="#SEC103">\stopbreaks</a>: Disallow page breaks.</li>
<li><a href="#SEC104">\telephone</a>: Your phone number.</li>
</ul>
<h3><a name="SEC92" href="#TOC92">\address</a></h3>
<p><a name="IDX197"></a></p>
<p><code>\address{Return address}</code></p>
<p>The return address, as it should appear on the letter and the
envelope. Separate lines of the address should be separated by
<code>\\</code> commands. If you do not make an
<code>\address</code> declaration, then the letter will be
formatted for copying onto your organization's standard letterhead.
If you give an <code>\address</code> declaration, then the letter
will be formatted as a personal letter.</p>
<h3><a name="SEC93" href="#TOC93">\cc</a></h3>
<p><a name="IDX198"></a> <a name="IDX199"></a></p>
<p><code>\cc{Kate Schechter\\Rob McKenna}</code></p>
<p>Generate a list of other persons the letter was sent to. Each
name is printed on a separate line.</p>
<h3><a name="SEC94" href="#TOC94">\closing</a></h3>
<p><a name="IDX200"></a> <a name="IDX201"></a></p>
<p><code>\closing{text}</code></p>
<p>The letter closes with a <code>\closing</code> command,
i.e.,</p>
<pre>
\closing{Best Regards,}
</pre>
<h3><a name="SEC95" href="#TOC95">\encl</a></h3>
<p><a name="IDX202"></a> <a name="IDX203"></a></p>

<p>Generate a list of enclosed material.</p>
<h3><a name="SEC96" href="#TOC96">\location</a></h3>
<p><a name="IDX204"></a></p>
<p><code>\location{address}</code></p>
<p>This modifies your organization's standard address. This only
appears if the <code>firstpage</code> pagestyle is selected.</p>
<h3><a name="SEC97" href="#TOC97">\makelabels</a></h3>
<p><a name="IDX205"></a></p>
<p><code>\makelabels{number}</code></p>
<p>If you issue this command in the preamble, LaTeX will create a
sheet of address labels. This sheet will be output before the
letters.</p>
<h3><a name="SEC98" href="#TOC98">\name</a></h3>
<p><a name="IDX206"></a></p>
<p><code>\name{June Davenport}</code></p>
<p>Your name, used for printing on the envelope together with the

mandatory argument, <code>text</code>, is whatever text you wish to
start your letter, i.e.,</p>
<pre>
\opening{Dear Joe,}
</pre>
<h3><a name="SEC100" href="#TOC100">\ps</a></h3>

<p><a name="IDX210"></a></p>
<p><code>\signature{Harvey Swick}</code></p>
<p>Your name, as it should appear at the end of the letter
underneath the space for your signature. Items that should go on
separate lines should be separated by <code>\\</code> commands.</p>
<h3><a name="SEC102" href="#TOC102">\startbreaks</a></h3>
<p><a name="IDX211"></a></p>
<p><code>\startbreaks</code></p>
<p>Used after a <code>\stopbreaks</code> command to allow page

<p>The first thing LaTeX does when processing ordinary text is to
translate your input file into a string of glyphs and spaces. To
produce a printed document, this string must be broken into lines,
and these lines must be broken into pages. In some environments,
you do the line breaking yourself with the <code>\\</code> command,
but LaTeX usually does it for you.</p>
<ul>
<li><a href="#SEC106">\\</a>: Start a new line.</li>
<li><a href="#SEC107">\- (hyphenation)</a>: Insert explicit
hyphenation.</li>

<h3><a name="SEC106" href="#TOC106">\\</a></h3>
<p><a name="IDX217"></a> <a name="IDX218"></a></p>
<p><code>\\[*][extra-space]</code></p>
<p>The <code>\\</code> command tells LaTeX to start a new line. It
has an optional argument, <code>extra-space</code>, that specifies
how much extra vertical space is to be inserted before the next
line. This can be a negative amount.</p>
<p>The <code>\\*</code> command is the same as the ordinary
<code>\\</code> command except that it tells LaTeX not to start a
new page after the line.</p>
<h3><a name="SEC107" href="#TOC107">\-</a></h3>
<p><a name="IDX219"></a> <a name="IDX220"></a></p>
<p>The <code>\-</code> command tells LaTeX that it may hyphenate
the word at that point. LaTeX is very good at hyphenating, and it
will usually find all correct hyphenation points. The
<code>\-</code> command is used for the exceptional cases.</p>
<p>Note that when you insert <code>\-</code> commands in a word,
the word will only be hyphenated at those points and not at any of
the hyphenation points that LaTeX might otherwise have chosen.</p>
<h3><a name="SEC108" href="#TOC108">\cleardoublepage</a></h3>
<p><a name="IDX221"></a> <a name="IDX222"></a></p>
<p>The <code>\cleardoublepage</code> command ends the current page
and causes all figures and tables that have so far appeared in the
input to be printed. In a two-sided printing style, it also makes
the next page a right-hand (odd-numbered) page, producing a blank
page if necessary.</p>
<h3><a name="SEC109" href="#TOC109">\clearpage</a></h3>
<p><a name="IDX223"></a> <a name="IDX224"></a></p>
<p>The <code>\clearpage</code> command ends the current page and
causes all figures and tables that have so far appeared in the
input to be printed.</p>
<h3><a name="SEC110" href="#TOC110">\enlargethispage</a></h3>
<p><a name="IDX225"></a> <a name="IDX226"></a></p>
<p><code>\enlargethispage{size}</code></p>
<p><code>\enlargethispage*{size}</code></p>
<p>Enlarge the <code>\textheight</code> for the current page by the
specified amount; e.g. <code>\enlargethispage{\baselineskip}</code>
will allow one additional line.</p>
<p>The starred form tries to squeeze the material together on the
page as much as possible. This is normally used together with an
explicit <code>\pagebreak</code>.</p>
<h3><a name="SEC111" href="#TOC111">\fussy</a></h3>
<p><a name="IDX227"></a></p>
<p><code>\fussy</code></p>
<p>This declaration (which is the default) makes TeX more fussy
about line breaking. This can avoids too much space between words,
but may produce overfull boxes.</p>
<p>This command cancels the effect of a previous
<code>\sloppy</code> command. section <a href=
"#SEC119">\sloppy</a></p>
<h3><a name="SEC112" href="#TOC112">\hyphenation</a></h3>
<p><a name="IDX228"></a> <a name="IDX229"></a></p>
<p><code>\hyphenation{words}</code></p>
<p>The <code>\hyphenation</code> command declares allowed
hyphenation points, where <code>words</code> is a list of words,
separated by spaces, in which each hyphenation point is indicated
by a <code>-</code> character.</p>
<h3><a name="SEC113" href="#TOC113">\linebreak</a></h3>
<p><a name="IDX230"></a> <a name="IDX231"></a></p>
<p><code>\linebreak[number]</code></p>
<p>The <code>\linebreak</code> command tells LaTeX to break the
current line at the point of the command. With the optional
argument, <code>number</code>, you can convert the
<code>\linebreak</code> command from a demand to a request. The
number must be a number from 0 to 4. The higher the number, the
more insistent the request is.</p>
<p>The <code>\linebreak</code> command causes LaTeX to stretch the
line so it extends to the right margin.</p>
<h3><a name="SEC114" href="#TOC114">\newline</a></h3>
<p><a name="IDX232"></a> <a name="IDX233"></a></p>
<p>The <code>\newline</code> command breaks the line right where it
is. It can only be used in paragraph mode.</p>
<h3><a name="SEC115" href="#TOC115">\newpage</a></h3>
<p><a name="IDX234"></a> <a name="IDX235"></a></p>
<p>The <code>\newpage</code> command ends the current page.</p>
<h3><a name="SEC116" href="#TOC116">\nolinebreak</a></h3>
<p><a name="IDX236"></a></p>
<p><code>\nolinebreak[number]</code></p>
<p>The <code>\nolinebreak</code> command prevents LaTeX from
breaking the current line at the point of the command. With the
optional argument, <code>number</code>, you can convert the
<code>\nolinebreak</code> command from a demand to a request. The
number must be a number from 0 to 4. The higher the number, the
more insistent the request is.</p>
<h3><a name="SEC117" href="#TOC117">\nopagebreak</a></h3>
<p><a name="IDX237"></a></p>
<p><code>\nopagebreak[number]</code></p>
<p>The <code>\nopagebreak</code> command prevents LaTeX from
breaking the current page at the point of the command. With the
optional argument, <code>number</code>, you can convert the
<code>\nopagebreak</code> command from a demand to a request. The
number must be a number from 0 to 4. The higher the number, the
more insistent the request is.</p>
<h3><a name="SEC118" href="#TOC118">\pagebreak</a></h3>
<p><a name="IDX238"></a> <a name="IDX239"></a></p>
<p><code>\pagebreak[number]</code></p>
<p>The <code>\pagebreak</code> command tells LaTeX to break the

<p>To get an expression <i>exp</i> to appear as a subscript, you
just type <code>_{</code><i>exp</i><code>}</code>. To get
<i>exp</i> to appear as a superscript, you type
<code>^{</code><i>exp</i><code>}</code>. LaTeX handles
superscripted superscripts and all of that stuff in the natural
way. It even does the right thing when something has both a
subscript and a superscript.</p>

<p>LaTeX provides almost any mathematical symbol you're likely to
need. The commands for generating them can be used only in math
mode. For example, if you include <code>$\pi$</code> in your
source, you will get the symbol in your output.</p>

type and puts in the spacing that it thinks is best. LaTeX formats
mathematics the way it's done in mathematics texts. If you want
different spacing, LaTeX provides the following four commands for
use in math mode:</p>

<dt><code><a name="IDX276">\ddots</a></code></dt>
<dd>Produces a diagonal ellipsis. eg.</dd>
<dt><code><a name="IDX277">\frac{num}{den}</a></code></dt>
<dd>Produces the fraction <code>num</code> divided by
<code>den</code>. eg.</dd>
<dt><code><a name="IDX278">\ldots</a></code></dt>
<dd>Produces an ellipsis. This command works in any mode, not just

<dd>Causes the argument text to be overlined. eg.</dd>
<dt><code><a name="IDX281">\sqrt[root]{arg}</a></code></dt>

<p>When LaTeX is processing your input text, it is always in one of
three modes:</p>
<ul>
<li>Paragraph mode</li>
<li>Math mode</li>
<li>Left-to-right mode, called LR mode for short</li>
</ul>
<p>LaTeX changes mode only when it goes up or down a staircase to a
different level, though not all level changes produce mode changes.
Mode changes occur only when entering or leaving an environment, or
when LaTeX is processing the argument of certain text-producing
commands.</p>
<p>"Paragraph mode" is the most common; it's the one LaTeX is in
when processing ordinary text. In that mode, LaTeX breaks your text
into lines and breaks the lines into pages. LaTeX is in "math mode"
when it's generating a mathematical formula. In "LR mode", as in
paragraph mode, LaTeX considers the output that it produces to be a
string of words with spaces between them. However, unlike paragraph
mode, LaTeX keeps going from left to right; it never starts a new
line in LR mode. Even if you put a hundred words into an
<code>\mbox</code>, LaTeX would keep typesetting them from left to
right inside a single box, and then complain because the resulting
box was too wide to fit on the line.</p>
<p>LaTeX is in LR mode when it starts making a box with an
<code>\mbox</code> command. You can get it to enter a different
mode inside the box - for example, you can make it enter math mode
to put a formula in the box. There are also several text-producing
commands and environments for making a box that put LaTeX in
paragraph mode. The box make by one of these commands or
environments will be called a <code>parbox</code>. When LaTeX is in
paragraph mode while making a box, it is said to be in "inner
paragraph mode". Its normal paragraph mode, which it starts out in,
is called "outer paragraph mode".</p>

<p><code>\author{names}</code></p>
<p>The <code>\author</code> command declares the author(s), where
<code>names</code> is a list of authors separated by
<code>\and</code> commands. Use <code>\\</code> to separate lines
within a single author's entry -- for example, to give the author's

<p>The valid options are:</p>
<ul>
<li><code>plain</code> - Just a plain page number.</li>
<li><code>empty</code> - Produces empty heads and feet - no page

<pre>
\markboth{left head}{right head}
</pre>
<p>The <code>\markboth</code> command is used in conjunction with
the page style <code>myheadings</code> for setting both the left
and the right heading. You should note that a "left-hand heading"
is generated by the last <code>\markboth</code> command before the
end of the page, while a "right-hand heading" is generated by the
first <code>\markboth</code> or <code>\markright</code> that comes
on the page if there is one, otherwise by the last one before the

<p><a name="IDX306"></a></p>
<pre>
\markright{right head}
</pre>
<p>The <code>\markright</code> command is used in conjunction with
the page style <code>myheadings</code> for setting the right
heading, leaving the left heading unchanged. You should note that a
"left-hand heading" is generated by the last <code>\markboth</code>

<li>The table of contents</li>
<li>The running head at the top of the page</li>
</ol>
<p>You may not want the same thing to appear in these other two
places as appears in the text heading. To handle this situation,
the sectioning commands have an <code>optional</code> argument that
provides the text for these other two purposes.</p>
<p>All sectioning commands have <code>*</code>-forms that print a

<h3><a name="SEC145" href="#TOC145">\hfill</a></h3>
<p><a name="IDX319"></a></p>
<p>The <code>\hfill</code> fill command produces a "rubber length"

spaces.</p>
<h3><a name="SEC146" href="#TOC146">\hrulefill</a></h3>
<p><a name="IDX320"></a></p>
<p>The <code>\hrulefill</code> fill command produces a "rubber

with a horizontal rule.</p>
<h3><a name="SEC147" href="#TOC147">\hspace</a></h3>
<p><a name="IDX321"></a></p>
<p><code>\hspace[*]{length}</code></p>
<p>The <code>\hspace</code> command adds horizontal space. The
length of the space can be expressed in any terms that LaTeX
understands, i.e., points, inches, etc. You can add negative as
well as positive space with an <code>\hspace</code> command. Adding
negative space is like backspacing.</p>
<p>LaTeX removes horizontal space that comes at the end of a line.
If you don't want LaTeX to remove this space, include the optional
<code>*</code> argument. Then the space is never removed.</p>
<h3><a name="SEC148" href="#TOC148">\addvspace</a></h3>
<p><a name="IDX322"></a> <a name="IDX323"></a> <a name=
"IDX324"></a></p>
<p><code>\addvspace{length}</code></p>
<p>The <code>\addvspace</code> command normally adds a vertical
space of height length. However, if vertical space has already been
added to the same point in the output by a previous
<code>\addvspace</code> command, then this command will not add
more space than needed to make the natural length of the total
vertical space equal to <code>length</code>.</p>
<h3><a name="SEC149" href="#TOC149">\bigskip</a></h3>
<p><a name="IDX325"></a></p>
<p>The <code>\bigskip</code> command is equivalent to

<p><code>\vspace[*]{length}</code></p>
<p>The <code>\vspace</code> command adds vertical space. The length
of the space can be expressed in any terms that LaTeX understands,
i.e., points, inches, etc. You can add negative as well as positive
space with an <code>\vspace</code> command.</p>
<p>LaTeX removes vertical space that comes at the end of a page. If

<h3><a name="SEC154" href="#TOC154">\fbox</a></h3>
<p><a name="IDX330"></a></p>
<p><code>\fbox{text}</code></p>
<p>The <code>\fbox</code> command is exactly the same as the
<code>\mbox</code> command, except that it puts a frame around the
outside of the box that it creates.</p>
<h3><a name="SEC155" href="#TOC155">\framebox</a></h3>
<p><a name="IDX331"></a></p>
<p><code>\framebox[width][position]{text}</code></p>
<p>The <code>\framebox</code> command is exactly the same as the
<code>\makebox</code> command, except that it puts a frame around
the outside of the box that it creates.</p>
<p>The framebox command produces a rule of thickness
<code>\fboxrule</code>, and leaves a space <code>\fboxsep</code>
between the rule and the contents of the box.</p>

<code>cmd</code>, which must have been declared with
<code>\newsavebox</code>.</p>
<h3><a name="SEC157" href="#TOC157">\makebox</a></h3>
<p><a name="IDX333"></a></p>
<p><code>\makebox[width][position]{text}</code></p>
<p>The <code>\makebox</code> command creates a box just wide enough
to contain the <code>text</code> specified. The width of the box is
specified by the optional <code>width</code> argument. The position
of the text within the box is determined by the optional
<code>position</code> argument.</p>
<ul>
<li><code>c</code> -- centred (default)</li>
<li><code>l</code> -- flushleft</li>
<li><code>r</code> -- flushright</li>
<li><code>s</code> -- stretch from left to right margin. The text

<h3><a name="SEC158" href="#TOC158">\mbox</a></h3>
<p><a name="IDX334"></a></p>
<p><code>\mbox{text}</code></p>
<p>The <code>\mbox</code> command creates a box just wide enough to

<p>Use this command to prevent text from being split across
lines.</p>
<h3><a name="SEC159" href="#TOC159">\newsavebox</a></h3>
<p><a name="IDX335"></a></p>
<p><code>\newsavebox{cmd}</code></p>

<h3><a name="SEC160" href="#TOC160">\parbox</a></h3>
<p><a name="IDX336"></a></p>
<p>
<code>\parbox[position][height][inner-pos]{width}{text}</code></p>
<p>A <code>parbox</code> is a box whose contents are created in
<code>paragraph</code> mode. The <code>\parbox</code> has two
mandatory arguments:</p>
<ul>
<li><code>width</code> - specifies the width of the parbox,
and</li>
<li><code>text</code> - the text that goes inside the parbox.</li>
</ul>
<p>LaTeX will position a <code>parbox</code> so its center lines up
with the center of the text line. The optional <i>position</i>
argument allows you to line up either the top or bottom line in the
parbox (default is top).</p>
<p>If the <i>height</i> argument is not given, the box will have
the natural height of the text.</p>
<p>The <i>inner-pos</i> argument controls the placement of the text
inside the box. If it is not specified, <i>position</i> is
used.</p>
<ul>
<li><code>t</code> -- text is placed at the top of the box.</li>
<li><code>c</code> -- text is centred in the box.</li>
<li><code>b</code> -- text is placed at the bottom of the box.</li>
<li><code>s</code> -- stretch vertically. The text must contain
vertically stretchable space for this to work.</li>
</ul>
<p>A <code>\parbox</code> command is used for a parbox containing a
small piece of text, with nothing fancy inside. In particular, you
shouldn't use any of the paragraph-making environments inside a
<code>\parbox</code> argument. For larger pieces of text, including
ones containing a paragraph-making environment, you should use a
<code>minipage</code> environment See section <a href=
"#SEC46">minipage</a>.</p>
<h3><a name="SEC161" href="#TOC161">\raisebox</a></h3>
<p><a name="IDX337"></a></p>
<p>
<code>\raisebox{distance}[extend-above][extend-below]{text}</code></p>
<p>The <code>\raisebox</code> command is used to raise or lower
text. The first mandatory argument specifies how high the text is
to be raised (or lowered if it is a negative amount). The text
itself is processed in <code>LR mode</code>.</p>
<p>Sometimes it's useful to make LaTeX think something has a
different size than it really does - or a different size than LaTeX
would normally think it has. The <code>\raisebox</code> command
lets you tell LaTeX how tall it is.</p>
<p>The first optional argument, <code>extend-above</code>, makes
LaTeX think that the text extends above the line by the amount
specified. The second optional argument, <code>extend-below</code>,
makes LaTeX think that the text extends below the line by the
amount specified.</p>
<h3><a name="SEC162" href="#TOC162">\rule</a></h3>
<p><a name="IDX338"></a></p>
<p><code>\rule[raise-height]{width}{thickness}</code></p>
<p>The <code>\rule</code> command is used to produce horizontal
lines. The arguments are defined as follows:</p>
<ul>
<li><code>raise-height</code> - specifies how high to raise the
rule (optional)</li>
<li><code>width</code> - specifies the length of the rule
(mandatory)</li>
<li><code>thickness</code> - specifies the thickness of the rule
(mandatory)</li>

<p>The following characters play a special role in LaTeX and are
called "special printing characters", or simply "special
characters".</p>
<pre>
# $ % & ~ _ ^ \ { }
</pre>
<p>Whenever you put one of these special characters into your file,
you are doing something special. If you simply want the character
to be printed just as any other letter, include a <code>\</code> in
front of the character. For example, <code>\$</code> will produce
<code>$</code> in your output.</p>
<p>One exception to this rule is the <code>\</code> itself because
<code>\\</code> has its own special meaning. A <code>\</code> is
produced by typing <code><a name="IDX346">$\backslash$</a></code>
in your file.</p>
<p>Also, <code>\~</code> means `place a tilde accent over the
following letter', so you will probably want to use
<code>\verb</code> instead.</p>
<p><a name="IDX348"></a></p>
<p>In addition, you can access any character of a font once you
know its number by using the <code><a name=
"IDX347">\symbol</a></code> command. For example, the character
used for displaying spaces in the <code>\verb*</code> command has
the code decimal 32, so it can be typed as
<code>\symbol{32}</code>.</p>
<p>You can also specify octal numbers with <code>'</code> or
hexadecimal numbers with <code>"</code>, so the previous example
could also be written as <code>\symbol{'40}</code> or
<code>\symbol{"20}</code>.</p>

<p><code>\include{file}</code></p>
<p>The <code>\include</code> command is used in conjunction with
the <code>\includeonly</code> command for selective inclusion of
files. The <code>file</code> argument is the first name of a file,
denoting <tt>`file.tex'</tt>. If <code>file</code> is one the file

<p>except that if the file <tt>`file.tex'</tt> does not exist, then
a warning message rather than an error is produced. If the file is

<p>A table of contents is produced with the <code><a name=
"IDX357">\tableofcontents</a></code> command. You put the command
right where you want the table of contents to go; LaTeX does the
rest for you. It produces a heading, but it does not automatically
start a new page. If you want a new page after the table of
contents, include a <code>\newpage</code> command after the
<code>\tableofcontents</code> command.</p>
<p>There are similar commands <code><a name=
"IDX358">\listoffigures</a></code> and <code><a name=
"IDX359">\listoftables</a></code> for producing a list of figures
and a list of tables, respectively. Everything works exactly the
same as for the table of contents.</p>
<p>NOTE: If you want any of these items to be generated, you cannot
have the <code><a name="IDX360">\nofiles</a></code> command in your
document.</p>
<ul>
<li><a href="#SEC173">\addcontentsline</a>: Add an entry to table
of contents etc.</li>
<li><a href="#SEC174">\addtocontents</a>: Add text directly to
table of contents file etc.</li>
</ul>
<h3><a name="SEC173" href="#TOC173">\addcontentsline</a></h3>
<p><a name="IDX361"></a></p>
<p><code>\addcontentsline{file}{sec_unit}{entry}</code></p>
<p>The <code>\addcontentsline</code> command adds an entry to the
specified list or table where:</p>
<ul>
<li><code>file</code> is the extension of the file on which
information is to be written: <code>toc</code> (table of contents),
<code>lof</code> (list of figures), or <code>lot</code> (list of
tables).</li>
<li><code>sec_unit</code> controls the formatting of the entry. It
should be one of the following, depending upon the value of the
file argument:
<ol>
<li><code>toc</code> -- the name of the sectional unit, such as
part or subsection.</li>
<li><code>lof</code> -- figure</li>
<li><code>lot</code> -- table</li>
</ol>
</li>
<li><code>entry</code> is the text of the entry.</li>
</ul>
<h3><a name="SEC174" href="#TOC174">\addtocontents</a></h3>
<p><a name="IDX362"></a></p>
<p><code>\addtocontents{file}{text}</code></p>
<p>The <code>\addtocontents</code> command adds text (or formatting
commands) directly to the file that generates the table of contents
or list of figures or tables.</p>
<ul>
<li><code>file</code> is the extension of the file on which
information is to be written: <code>toc</code> (table of contents),
<code>lof</code> (list of figures), or <code>lot</code> (list of
tables).</li>
<li><code>text</code> is the information to be written.</li>

</ul>
<h3><a name="SEC176" href="#TOC176">\typein</a></h3>
<p><a name="IDX365"></a></p>
<p><code>\typein[cmd]{msg}</code></p>
<p>Prints <code>msg</code> on the terminal and causes LaTeX to stop
and wait for you to type a line of input, ending with return. If
the <code>cmd</code> argument is missing, the typed input is
processed as if it had been included in the input file in place of
the <code>\typein</code> command. If the <code>cmd</code> argument
is present, it must be a command name. This command name is then
defined or redefined to be the typed input.</p>
<h3><a name="SEC177" href="#TOC177">\typeout</a></h3>
<p><a name="IDX366"></a></p>
<p><code>\typeout{msg}</code></p>
<p>Prints <code>msg</code> on the terminal and in the
<code>log</code> file. Commands in <code>msg</code> that are
defined with <code>\newcommand</code> or <code>\renewcommand</code>
are replaced by their definitions before being printed.</p>
<p>LaTeX's usual rules for treating multiple spaces as a single
space and ignoring spaces after a command name apply to
<code>msg</code>. A <code>\space</code> command in <code>msg</code>
causes a single space to be printed. A <code>^^J</code> in
<code>msg</code> prints a newline.</p>

<p>The following type style commands are supported by LaTeX.</p>
<p>These commands are used like <code>\textit{italics text}</code>.
The corresponding command in parenthesis is the "declaration form",
which takes no arguments. The scope of the declaration form lasts
until the next type style command or the end of the current
group.</p>
<p>The declaration forms are cumulative; i.e., you can say
<code>\sffamily\bfseries</code> to get sans serif boldface.</p>
<p>You can also use the environment form of the declaration forms;
e.g. <code>\begin{ttfamily}...\end{ttfamily}</code>.</p>

<p><a name="IDX414"></a> <a name="IDX415"></a></p>
<p>These commands are primarily intended for writers of macros and
packages. The commands listed here are only a subset of the
available ones. For full details, you should consult Chapter 7 of
<cite>The LaTeX Companion</cite>.</p>
<dl>
<dt><code><a name="IDX416">\fontencoding{enc}</a></code></dt>
<dd>Select font encoding. Valid encodings include <code>OT1</code>
and <code>T1</code>.</dd>
<dt><code><a name="IDX417">\fontfamily{family}</a></code></dt>
<dd>Select font family. Valid families include:
<ul>
<li><code>cmr</code> for Computer Modern Roman</li>
<li><code>cmss</code> for Computer Modern Sans Serif</li>
<li><code>cmtt</code> for Computer Modern Typewriter</li>
</ul>
and numerous others.</dd>
<dt><code><a name="IDX418">\fontseries{series}</a></code></dt>
<dd>Select font series. Valid series include:
<ul>
<li><code>m</code> Medium (normal)</li>
<li><code>b</code> Bold</li>
<li><code>c</code> Condensed</li>
<li><code>bc</code> Bold condensed</li>
<li><code>bx</code> Bold extended</li>
</ul>
and various other combinations.</dd>
<dt><code><a name="IDX419">\fontshape{shape}</a></code></dt>
<dd>Select font shape. Valid shapes are:
<ul>
<li><code>n</code> Upright (normal)</li>
<li><code>it</code> Italic</li>
<li><code>sl</code> Slanted (oblique)</li>
<li><code>sc</code> Small caps</li>
<li><code>ui</code> Upright italics</li>
<li><code>ol</code> Outline</li>
</ul>
The two last shapes are not available for most font families.</dd>
<dt><code><a name="IDX420">\fontsize{size}{skip}</a></code></dt>
<dd>Set font size. The first parameter is the font size to switch
to; the second is the <code>\baselineskip</code> to use. The unit
of both parameters defaults to pt. A rule of thumb is that the
baselineskip should be 1.2 times the font size.</dd>
<dt><code><a name="IDX421">\selectfont</a></code></dt>
<dd>The changes made by calling the four font commands described
above do not come into effect until <code>\selectfont</code> is
called.</dd>
<dt><code><a name=
"IDX422">\usefont{enc}{family}{series}{shape}</a></code></dt>
<dd>Equivalent to calling <code>\fontencoding</code>,
<code>\fontfamily</code>, <code>\fontseries</code> and
<code>\fontshape</code> with the given parameters, followed by
<code>\selectfont</code>.</dd>
