Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Load the fontenc package and choose T1 font encoding."

A block of code is set as follows:

\[
  \int_a^b \! f(x) \, dx = \lim_{\Delta x \rightarrow 0}
  \sum_{i=1}^{n} f(x_i) \,\Delta x_i
\]

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

\documentclass{book}
\usepackage{cleveref}
\crefname{enumi}{position}{positions}
\begin{document}
\chapter{Statistics}
\label{stats}
\section{Most used packages by LaTeX.org users}
\label{packages}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Click the Typeset button to compile the document."
