我想在每一页的背景中插入章节标题。（也可以是章节标题）
我搜索了一下，除了当前章节标题之外没有找到任何其他内容。
MWE-1：
\documentclass{article}
\usepackage{lipsum}
\begin{document}
\section{The first section}
\lipsum[1-3]
\section{The second section}
\lipsum[1-3]
\section{The third section}
\lipsum[1-3]
\section{The fourth section}
Hi, I'm the 4th.
The title of the 2nd section is... ?? Huh??
\section{The fifth section}
\lipsum[1-3]
\section{The sixth section}
\lipsum[1-3]
\section{The seventh section}
\lipsum[1-3]
\end{document}
MWE-2：
实际上，我需要在以下选项卡按钮中排版实际的部分标题：
\documentclass{article}
\usepackage[a5paper,vmargin=2cm]{geometry}
\usepackage{background}
\usepackage{etoolbox}
\usepackage{totcount}
\usepackage{lipsum}
% to have access to the total number of sections
\regtotcounter{section}
% every section starts on a new page
\pretocmd{\section}{\clearpage}{}{}
% auxiliary lengths for the height of the frame and the width of each tab
\newlength\frameheight
\newlength\avgtabwidth
% style for the section tabs
\tikzset{tab/.style={
text width=\avgtabwidth,anchor=south,
draw=gray,thick,rectangle,rounded corners=12pt,rotate=270,
align=center,text height=20pt,
text depth=25pt,inner sep=0pt,fill=gray!20,
yshift=-18pt,font=\sffamily\LARGE}}
% style for the current section tab
\tikzset{selectedtab/.style={tab,color=white,fill=gray!90}}
% the page number is showed in the background material
\pagestyle{empty}
\AtBeginDocument{
% calculation of the width for each tab
\setlength\frameheight{\dimexpr\textheight+2cm\relax}
\ifnum\totvalue{section}>0
\setlength\avgtabwidth{\dimexpr\frameheight/\totvalue{section}\relax}
\fi
% the main part; as background material we place the border,
% the section (current and other) tabs and the page number
\backgroundsetup{scale=1, color=black, angle=0, opacity=1, contents={
\begin{tikzpicture}[remember picture, overlay]
\node[inner sep=0pt, text width=\the\dimexpr\textwidth+1.5cm]
at (current page.center) (border)
{\rule{0pt}{\dimexpr\textheight+2cm\relax}};
\foreach \valsection in {0,...,\numexpr\totvalue{section}-1\relax} {
\node[\ifnum\thesection<\numexpr\valsection+1 tab\relax
\else \ifnum\thesection>\numexpr\valsection+1 tab\relax
\else selectedtab\fi\fi,
xshift=(0.5+\valsection)*\avgtabwidth]
at (border.north east) (tab-\valsection)
{Section \the\numexpr\valsection+1\relax};
}
\node[draw=gray, line width=2pt, rectangle, rounded corners=10pt,
inner sep=0pt, text width=\the\dimexpr\textwidth+1.5cm\relax, fill=white]
at (current page.center) {\rule{0pt}{\dimexpr\textheight+2cm\relax}};
\node[font=\LARGE\sffamily,fill=white]
at (border.south) {\makebox[3em][c]{\thepage}};
\end{tikzpicture}
}}
}
\begin{document}
\section{Test Section One}
\lipsum[1-3]
\section{Test Section Two}
\lipsum[1-3]
\section{Test Section Three}
\lipsum[1-3]
\section{Test Section Four}
\lipsum[2]
\end{document}

这是 MWE 的稍微修改后的版本，它展示了如何以自动方式插入部分名称：
\documentclass{article}
\usepackage[a5paper,vmargin=2cm]{geometry} % http://ctan.org/pkg/geometry
\usepackage{background} % http://ctan.org/pkg/background
\usepackage{etoolbox} % http://ctan.org/pkg/etoolbox
\usepackage{totcount} % http://ctan.org/pkg/totcount
\usepackage{lipsum} % http://ctan.org/pkg/lipsum
\usepackage{nameref} % http://ctan.org/pkg/nameref
% Automatically insert `\label` with every `\section`
\let\oldsection\section
\renewcommand{\section}[2][\relax]{%
\ifx#1\relax
\oldsection{#2}%
\else
\oldsection[#1]{#2}%
\fi%
\label{sec:\thesection}%
}
% to have access to the total number of sections
\regtotcounter{section}
% every section starts on a new page
\pretocmd{\section}{\clearpage}{}{}
% auxiliary lengths for the height of the frame and the width of each tab
\newlength\frameheight
\newlength\avgtabwidth
% style for the section tabs
\tikzset{tab/.style={
text width=\avgtabwidth,anchor=south,
draw=gray,thick,rectangle,rounded corners=12pt,rotate=270,
align=center,text height=20pt,
text depth=25pt,inner sep=0pt,fill=gray!20,
yshift=-18pt,font=\sffamily\LARGE}}
% style for the current section tab
\tikzset{selectedtab/.style={tab,color=white,fill=gray!90}}
% the page number is showed in the background material
\pagestyle{empty}
\AtBeginDocument{
% calculation of the width for each tab
\setlength\frameheight{\dimexpr\textheight+2cm\relax}
\ifnum\totvalue{section}>0
\setlength\avgtabwidth{\dimexpr\frameheight/\totvalue{section}\relax}
\fi
% the main part; as background material we place the border,
% the section (current and other) tabs and the page number
\backgroundsetup{scale=1, color=black, angle=0, opacity=1, contents={
\begin{tikzpicture}[remember picture, overlay]
\node[inner sep=0pt, text width=\the\dimexpr\textwidth+1.5cm]
at (current page.center) (border)
{\rule{0pt}{\dimexpr\textheight+2cm\relax}};
\foreach \valsection in {0,...,\numexpr\totvalue{section}-1\relax} {
\node[\ifnum\thesection<\numexpr\valsection+1 tab\relax
\else \ifnum\thesection>\numexpr\valsection+1 tab\relax
\else selectedtab\fi\fi,
xshift=(0.5+\valsection)*\avgtabwidth]
at (border.north east) (tab-\valsection)
{\nameref{sec:\the\numexpr\valsection+1\relax}};
}
\node[draw=gray, line width=2pt, rectangle, rounded corners=10pt,
inner sep=0pt, text width=\the\dimexpr\textwidth+1.5cm\relax, fill=white]
at (current page.center) {\rule{0pt}{\dimexpr\textheight+2cm\relax}};
\node[font=\LARGE\sffamily,fill=white]
at (border.south) {\makebox[3em][c]{\thepage}};
\end{tikzpicture}
}}
}
\begin{document}
\section[First]{Test Section One}
\lipsum[1-3]
\section[Second]{Test Section Two}
\lipsum[1-3]
\section[Third]{Test Section Three}
\lipsum[1-3]
\section[Fourth]{Test Section Four}
\lipsum[2]
\end{document}
这些变化包括：
- 修改
\section为自动插入表单的标签sec:\thesection；以及 sec:<num>检索使用标签的部分的名称nameref。
当然，这种\section修改并不是最理想的，因为它不允许使用星号*变体。但是，在您的实施中可能不需要这样做，因为您无论如何都会以标签的形式列出章节标题。无论如何，如果需要，可以改进/更改这一点。
