LaTeX commands you actually type

Updated 2026-09

This is not every command in TeX. It is the set you type in a Textira draft. The venue class already loaded packages; if a command is missing here, the shell may not provide it.

How to read the table

A command takes arguments on one line. An environment has begin/end and wraps a block. If that split is unclear, open Command vs environment. Lengths have their own page so you do not resize a venue column by hand.

Text

\emph{…}
Semantic emphasis. Safer nesting than \textit.
\textbf{…}
Bold. Do not fake a heading with it.
\textit{…}
Italic. Terms and titles; prefer \emph for stress.
\texttt{…}
Monospace. Identifiers, paths, command names.
\textsc{…}
Small caps. Some venue fonts only fake them.
\mbox{…} / \textrm{…}
A short unbreakable word inside math.
\noindent
Skip indent on this paragraph. Do not zero parindent for the paper.
\vspace{…}
Local vertical space. Rare in a venue draft—it shoves floats.

Sections and pointers

\section{…}
Top-level section. Conference papers rarely need deeper than subsection.
\subsection{…}
A subsection.
\paragraph{…}
Run-in heading. Sometimes used in related work.
\label{…}
Names the current counter. Must follow the caption.
\ref{…}
The number of a section, figure, or table.
\eqref{…}
An equation number, with parentheses.
\url{…}
A breakable URL. Do not force a long DOI into \texttt.

Math

\begin{equation}
One numbered display.
\begin{align}
Aligned rows. Put & before the relation.
\begin{gather}
Several centered lines, not aligned.
\frac{a}{b}
A fraction. Fine in displays; consider \tfrac inline.
\sum / \prod / \int
Big operators. Limits with _ and ^.
\left( … \right)
Fences that grow. Skip left/right on a plain parenthesis.
\mathrm{…}
Upright text in math, such as the letters in arg min.
\mathbf{…}
Bold Latin. Vectors more often use \boldsymbol or a macro.
\mathbb{R}
Blackboard bold. Needs amsfonts / amssymb.
\begin{pmatrix}
Parenthesis matrix. Square brackets: bmatrix.

Floats

\begin{figure}
A single-column figure.
\begin{figure*}
A full-width figure. Use this for wide plots in two-column venue layouts.
\includegraphics[width=…]{…}
Insert a graphic. Tie width to \linewidth, not a raw 400pt.
\caption{…}
The caption. Below figures, above tables.
\begin{table}
A single-column table.
\begin{tabular}{…}
Column spec, such as lcr or @{}l r@{}.
\toprule / \midrule / \bottomrule
A three-line table. Skip vertical rules.
\multicolumn{n}{c}{…}
A header that spans columns.

Citations

\cite{a,b}
Inserts cites in the template style.
\citet{key}
natbib textual: Smith (2024).
\citep{key}
natbib parenthetical: (Smith, 2024).
\bibliography{refs}
BibTeX list. The class owns the bst.
\printbibliography
biblatex list. Do not also call \bibliography.

FAQ

The card already lists some of these.
The card follows writing order. This page follows kind, so you can check one command’s caveats.
The template says undefined control sequence.
Check the spelling, then whether this class provides it. Venue classes rarely let you \usepackage{titlesec} to restyle headings.
