# Numbering chapter thumbs, removing 0 from toc

I'm using KOMA-Script for chapter-thumbs. How can I modify it to remove '0' chapter thumb from TOC ?

Use \lohead[]{} to remove the chapterthumbs and \loheadwithchapterthumbs{} to enable them.

\documentclass{scrbook}
\usepackage{rotating}
\usepackage{xcolor}
\usepackage{scrpage2}
\usepackage{chapterthumbs}
\usepackage{blindtext}% dummy text
\begin{document}
\tableofcontents
\cleardoublepage
\blinddocument
\end{document}


But note that package chapterthumbs is outdated because it is based on the deprecated package scrpage2.

I would suggest to use package chapterthumb which can be used with scrlayer-scrpage. chapterthumb.sty is part of the KOMA-Script book examples. You can download it from https://komascript.de/komascriptbuch5examples. It is in folder "Anhang-B" of the zip file.

\documentclass{scrbook}
\usepackage[ngerman]{babel}
\usepackage{chapterthumb}[2016/02/01]
\usepackage{scrlayer-scrpage}
\renewcommand*{\chapterthumbwidth}{.05\paperheight}
\renewcommand*{\chapterthumbskip}{.05\paperheight}
\renewcommand*{\chapterthumbformat}{\thechapter}

\usepackage{blindtext}% dummy text
\begin{document}
\tableofcontents
\blinddocument
\end{document}


Both examples work with the standard class book too.

If you want to enable and disable the chapter thumbs manually you can define commands which add or remove the layer chapterthumb to or from all layer page styles respectively:

\documentclass{scrbook}
\usepackage[ngerman]{babel}
\usepackage{chapterthumb}[2016/02/01]
\usepackage{scrlayer-scrpage}

\renewcommand*{\chapterthumbwidth}{.05\paperheight}
\renewcommand*{\chapterthumbskip}{.05\paperheight}
\renewcommand*{\chapterthumbformat}{\thechapter}

\newcommand*\chapterthumbson{%
}% command to enable chapter thumbs
\newcommand*\chapterthumbsoff{%
\RemoveLayersFromPageStyle{@everystyle@}{chapterthumb}%
}% command to disable chapter thums
\chapterthumbsoff% disable chapter thumbs
\usepackage{blindtext}% dummy text
\begin{document}
\tableofcontents
\blinddocument

\clearpage
\chapterthumbson% enable chapter thumbs
\blinddocument
\end{document}

• Thanks I will use it but when I'm applying your sample I'm getting: Package scrlayer Error: cannot define '\newpagestyle'. See the scrlayer package documentation for explanation. – bartzmc Apr 8 '17 at 6:01
• With my example or with your code? There is no MWE in your question. Maybe you load another package for page header and footer too? titleps? Note that this package can not be used together with chapterthumb (or chapterthumbs). The chapter thumbs are realized by pagestyles defined by scrlayer-scrpage/scrlayer (or scrpage2). – esdd Apr 8 '17 at 9:09
• Thanks, you were right, I had too many packages included, I have removed some of them and it's working. I have 3 chapters but I want chapterthumb numeration to start with second chapter, how can I do that? – bartzmc Apr 8 '17 at 11:47
• I have added a suggestion that allowes to enable and disable the chapter thumbs manually. – esdd Apr 8 '17 at 12:29
• It's only removing chapter thumb from first chapter. I want second chapter to start with 1st chapter thumb numeration. – bartzmc Apr 8 '17 at 12:46
