% \section{Introduction}
% \indent This \LaTeX{} package puts running, customizable thumb marks in the outer
% margin, moving downward as the chapter number (or whatever shall be marked
% by the thumb marks) increases. Additionally an overview page/table of thumb
% marks can be added automatically, which gives the respective names of the
% thumbed objects, the page where the object/thumb mark first appears,
% and the thumb mark itself at the respective position. The thumb marks are
% probably useful for documents, where a quick and easy way to find
% e.\,g.~a~chapter is needed, for example in reference guides, anthologies,
% or quite large documents.\\
% \xpackage{thumbs} must be loaded after the page size has been set,
% when printing the document \textquotedblleft shrink to
% page\textquotedblright\ should not be used, a printer capable of
% printing up to the border of the sheet of paper is needed
% (or afterwards cutting the paper).\\
% Usage with |\usepackage[landscape]{geometry}|,
% |\documentclass[landscape]{|\ldots|}|, |\usepackage[landscape]{geometry}|,
% |\usepackage{lscape}|, or |\usepackage{pdflscape}| is possible.\\
% There \emph{are} already some packages for creating thumbs, but because
% none of them did what I wanted, I wrote this new package.\footnote{Probably%
% this holds true for the motivation of the authors of quite a lot of packages.}
%
% \section{Usage}
%
% \subsection{Loading}
% \indent Load the package placing
% \begin{quote}
%   |\usepackage[<|\textit{options}|>]{thumbs}|
% \end{quote}
% \noindent in the preamble of your \LaTeXe\ source file.\\
% The \xpackage{thumbs} package takes the dimensions of the page
% |\AtBeginDocument| and does not react to changes afterwards.
% Therefore this package must be loaded \emph{after} the page dimensions
% have been set, e.\,g. with package \xpackage{geometry}
% (\url{http://ctan.org/pkg/geometry}). Of course it is also OK to just keep
% the default page/paper settings, but when anything is changed, it must be
% done before \xpackage{thumbs} executes its |\AtBeginDocument| code.\\
% The format of the paper, where the document shall be printed upon,
% should also be used for creating the document. Then the document can
% be printed without adapting the size, like e.\,g. \textquotedblleft shrink
% to page\textquotedblright . That would add a white border around the document
% and by moving the thumb marks from the edge of the paper they no longer appear
% at the side of the stack of paper. (Therefore e.\,g. for printing the example
% file to A4 paper it is necessary to add |a4paper| option to the document class
% and recompile it! Then the thumb marks column change will occur at another
% point, of course.) It is also necessary to use a printer
% capable of printing up to the border of the sheet of paper. Alternatively
% it is possible after the printing to cut the paper to the right size.
% While performing this manually is probably quite cumbersome,
% printing houses use paper, which is slightly larger than the
% desired format, and afterwards cut it to format.\\
% Some faulty \xfile{pdf}-viewer adds a white line at the bottom and
% right side of the document when presenting it. This does not change
% the printed version. To test for this problem, a page of the example
% file has been completely coloured. (Probably better exclude that page from
% printing\ldots)\\
% When using the thumb marks overview page, it is necessary to |\protect|
% entries like |\pi| (same as with entries in tables of contents, figures,
% tables,\ldots).\\
%
% \subsection{Options}
% \DescribeMacro{options}
% \indent The \xpackage{thumbs} package takes the following options:
%
% \subsubsection{linefill\label{sss:linefill}}
% \DescribeMacro{linefill}
% \indent Option |linefill| wants to know how the line between object
% (e.\,g.~chapter name) and page number shall be filled at the overview
% page. Empty option will result in a blank line, |line| will fill the distance
% with a line, |dots| will fill the distance with dots.
%
% \subsubsection{minheight\label{sss:minheight}}
% \DescribeMacro{minheight}
% \indent Option |minheight| wants to know the minimal vertical extension
%  of each thumb mark. This is only useful in combination with option |height=auto|
%  (see below). When the height is automatically calculated and smaller than
%  the |minheight| value, the height is set equal to the given |minheight| value
%  and a new column/page of thumb marks is used. The default value is
%  $47\unit{pt}$\ $(\approx 16.5\unit{mm} \approx 0.65\unit{in})$.
%
% \subsubsection{height\label{sss:height}}
% \DescribeMacro{height}
% \indent Option |height| wants to know the vertical extension of each thumb mark.
%  The default value \textquotedblleft |auto|\textquotedblright\ calculates
%  an appropriate value automatically decreasing with increasing number of thumb
%  marks (but fixed for each document). When the height is smaller than |minheight|,
%  this package deems this as too small and instead uses a new column/page of thumb
%  marks. If smaller thumb marks are really wanted, choose a smaller |minheight|
% (e.\,g.~$0\unit{pt}$).
%
% \subsubsection{width\label{sss:width}}
% \DescribeMacro{width}
% \indent Option |width| wants to know the horizontal extension of each thumb mark.
%  The default option-value \textquotedblleft |auto|\textquotedblright\ calculates
%  a width-value automatically: (|\paperwidth| minus |\textwidth|), which is the
%  total width of inner and outer margin, divided by~$4$. Instead of this, any
%  positive width given by the user is accepted. (Try |width={\paperwidth}|
%  in the example!) Option |width={autoauto}| leads to thumb marks, which are
%  just wide enough to fit the widest thumb mark text.
%
% \subsubsection{distance\label{sss:distance}}
% \DescribeMacro{distance}
% \indent Option |distance| wants to know the vertical spacing between
%  two thumb marks. The default value is $2\unit{mm}$.
%
% \subsubsection{topthumbmargin\label{sss:topthumbmargin}}
% \DescribeMacro{topthumbmargin}
% \indent Option |topthumbmargin| wants to know the vertical spacing between
%  the upper page (paper) border and top thumb mark. The default (|auto|)
%  is 1 inch plus |\th@bmsvoffset| plus |\topmargin|. Dimensions (e.\,g. $1\unit{cm}$)
%  are also accepted.
%
% \pagebreak
%
% \subsubsection{bottomthumbmargin\label{sss:bottomthumbmargin}}
% \DescribeMacro{bottomthumbmargin}
% \indent Option |bottomthumbmargin| wants to know the vertical spacing between
%  the lower page (paper) border and last thumb mark. The default (|auto|) for the
%  position of the last thumb is\\
%  |1in+\topmargin-\th@mbsdistance+\th@mbheighty+\headheight+\headsep+\textheight|
%  |+\footskip-\th@mbsdistance|\newline
%  |-\th@mbheighty|.\\
%  Dimensions (e.\,g. $1\unit{cm}$) are also accepted.
%
% \subsubsection{eventxtindent\label{sss:eventxtindent}}
% \DescribeMacro{eventxtindent}
% \indent Option |eventxtindent| expects a dimension (default value: $5\unit{pt}$,
% negative values are possible, of course),
% by which the text inside of thumb marks on even pages is moved away from the
% page edge, i.e. to the right. Probably using the same or at least a similar value
% as for option |oddtxtexdent| makes sense.
%
% \subsubsection{oddtxtexdent\label{sss:oddtxtexdent}}
% \DescribeMacro{oddtxtexdent}
% \indent Option |oddtxtexdent| expects a dimension (default value: $5\unit{pt}$,
% negative values are possible, of course),
% by which the text inside of thumb marks on odd pages is moved away from the
% page edge, i.e. to the left. Probably using the same or at least a similar value
% as for option |eventxtindent| makes sense.
%
% \subsubsection{evenmarkindent\label{sss:evenmarkindent}}
% \DescribeMacro{evenmarkindent}
% \indent Option |evenmarkindent| expects a dimension (default value: $0\unit{pt}$,
% negative values are possible, of course),
% by which the thumb marks (background and text) on even pages are moved away from the
% page edge, i.e. to the right. This might be usefull when the paper,
% onto which the document is printed, is later cut to another format.
% Probably using the same or at least a similar value as for option |oddmarkexdent|
% makes sense.
%
% \subsubsection{oddmarkexdent\label{sss:oddmarkexdent}}
% \DescribeMacro{oddmarkexdent}
% \indent Option |oddmarkexdent| expects a dimension (default value: $0\unit{pt}$,
% negative values are possible, of course),
% by which the thumb marks (background and text) on odd pages are moved away from the
% page edge, i.e. to the left. This might be usefull when the paper,
% onto which the document is printed, is later cut to another format.
% Probably using the same or at least a similar value as for option |oddmarkexdent|
% makes sense.
%
% \subsubsection{evenprintvoffset\label{sss:evenprintvoffset}}
% \DescribeMacro{evenprintvoffset}
% \indent Option |evenprintvoffset| expects a dimension (default value: $0\unit{pt}$,
% negative values are possible, of course),
% by which the thumb marks (background and text) on even pages are moved downwards.
% This might be usefull when a duplex printer shifts recto and verso pages
% against each other by some small amount, e.g. a~millimeter or two, which
% is not uncommon. Please do not use this option with another value than $0\unit{pt}$
% for files which you submit to other persons. Their printer probably shifts the
% pages by another amount, which might even lead to increased mismatch
% if both printers shift in opposite directions. Ideally the pdf viewer
% would correct the shift depending on printer (or at least give some option
% similar to \textquotedblleft shift verso pages by
% \hbox{$x\unit{mm}$\textquotedblright{}.}
%
% \subsubsection{thumblink\label{sss:thumblink}}
% \DescribeMacro{thumblink}
% \indent Option |thumblink| determines, what is hyperlinked at the thumb marks
% overview page (when the \xpackage{hyperref} package is used):
%
% \begin{description}
% \item[- |none|] creates \emph{none} hyperlinks
%
% \item[- |title|] hyperlinks the \emph{titles} of the thumb marks
%
% \item[- |page|] hyperlinks the \emph{page} numbers of the thumb marks
%
% \item[- |titleandpage|] hyperlinks the \emph{title and page} numbers of the thumb marks
%
% \item[- |line|] hyperlinks the whole \emph{line}, i.\,e. title, dots%
%        (or line or whatsoever) and page numbers of the thumb marks
%
% \item[- |rule|] hyperlinks the whole \emph{rule}.
% \end{description}
%
% \subsubsection{nophantomsection\label{sss:nophantomsection}}
% \DescribeMacro{nophantomsection}
% \indent Option |nophantomsection| globally disables the automatical placement of a
% |\phantomsection| before the thumb marks. Generally it is desirable to have a
% hyperlink from the thumbs overview page to lead to the thumb mark and not to some
% earlier place. Therefore automatically a |\phantomsection| is placed before each
% thumb mark. But for example when using the thumb mark after a |\chapter{...}|
% command, it is probably nicer to have the link point at the top of that chapter's
% title (instead of the line below it). When automatical placing of the
% |\phantomsection|s has been globally disabled, nevertheless manual use of
% |\phantomsection| is still possible. The other way round: When automatical placing
% of the |\phantomsection|s has \emph{not} been globally disabled, it can be disabled
% just for the following thumb mark by the command |\thumbsnophantom|.
%
% \subsubsection{ignorehoffset, ignorevoffset\label{sss:ignoreoffset}}
% \DescribeMacro{ignorehoffset}
% \DescribeMacro{ignorevoffset}
% \indent Usually |\hoffset| and |\voffset| should be regarded,
% but moving the thumb marks away from the paper edge probably
% makes them useless. Therefore |\hoffset| and |\voffset| are ignored
% by default, or when option |ignorehoffset| or |ignorehoffset=true| is used
% (and |ignorevoffset| or |ignorevoffset=true|, respectively).
% But in case that the user wants to print at one sort of paper
% but later trim it to another one, regarding the offsets would be
% necessary. Therefore |ignorehoffset=false| and |ignorevoffset=false|
% can be used to regard these offsets. (Combinations
% |ignorehoffset=true, ignorevoffset=false| and
% |ignorehoffset=false, ignorevoffset=true| are also possible.)\\
%
% \subsubsection{verbose\label{sss:verbose}}
% \DescribeMacro{verbose}
% \indent Option |verbose=false| (the default) suppresses some messages,
%  which otherwise are presented at the screen and written into the \xfile{log}~file.
%  Look for\\
%  |************** THUMB dimensions **************|\\
%  in the \xfile{log} file for height and width of the thumb marks as well as
%  top and bottom thumb marks margins.
%
% \subsubsection{draft\label{sss:draft}}
% \DescribeMacro{draft}
% \indent Option |draft| (\emph{not} the default) sets the thumb mark width to
% $2\unit{pt}$, thumb mark text colour to black and thumb mark background colour
% to grey (|gray|). Either do not use this option with the \xpackage{thumbs} package at all,
% or use |draft=false|, or |final|, or |final=true| to get the original appearance
% of the thumb marks.\\
%
% \subsubsection{hidethumbs\label{sss:hidethumbs}}
% \DescribeMacro{hidethumbs}
% \indent Option |hidethumbs| (\emph{not} the default) prevents \xpackage{thumbs}
% to create thumb marks (or thumb marks overview pages). This could be useful
% when thumb marks were placed, but for some reason no thumb marks (and overview pages)
% shall be placed. Removing |\usepackage[...]{thumbs}| would not work but
% create errors for unknown commands (e.\,g. |\addthumb|, |\addtitlethumb|,
% |\thumbnewcolumn|, |\stopthumb|, |\continuethumb|, |\addthumbsoverviewtocontents|,
% |\thumbsoverview|, |\thumbsoverviewback|, |\thumbsoverviewverso|, and
% |\thumbsoverviewdouble|). (A~|\jobname.tmb| file is created nevertheless.)~--

% \subsubsection{\textbackslash addthumb}
% \DescribeMacro{\addthumb}
% To add a thumb mark, use the |\addthumb| command, which has these four parameters:
% \begin{enumerate}
% \item a title for the thumb mark (for the thumb marks overview page,
%         e.\,g. the chapter title),
%
% \item the text to be displayed in the thumb mark (for example the chapter
%         number: |\thechapter|),
%
% \item the colour of the text in the thumb mark,
%
% \item and the background colour of the thumb mark
% \end{enumerate}
% (parameters in this order) at the page where you want this thumb mark placed
% (for the first time).\\
%
% \subsubsection{\textbackslash addtitlethumb}
% \DescribeMacro{\addtitlethumb}
% When a thumb mark shall not or cannot be placed on a page, e.\,g.~at the title page or
% when using |\includepdf| from \xpackage{pdfpages} package, but the reference in the thumb
% marks overview nevertheless shall name that page number and hyperlink to that page,
% |\addtitlethumb| can be used at the following page. It has five arguments. The arguments
% one to four are identical to the ones of |\addthumb| (see above),
% and the fifth argument consists of the label of the page, where the hyperlink
% at the thumb marks overview page shall link to. The \xpackage{thumbs} package does
% \emph{not} create that label! But for the first page the label
% \texttt{pagesLTS.0} can be use, which is already placed there by the used
% \xpackage{pageslts} package.\\
%
% \subsubsection{\textbackslash stopthumb and \textbackslash continuethumb}
% \DescribeMacro{\stopthumb}
% \DescribeMacro{\continuethumb}
% When a page (or pages) shall have no thumb marks, use the |\stopthumb| command
% (without parameters). Placing another thumb mark with |\addthumb| or |\addtitlethumb|
% or using the command |\continuethumb| continues the thumb marks.\\
%
% \subsubsection{\textbackslash thumbsoverview/back/verso/double}
% \DescribeMacro{\thumbsoverview}
% \DescribeMacro{\thumbsoverviewback}
% \DescribeMacro{\thumbsoverviewverso}
% \DescribeMacro{\thumbsoverviewdouble}
% The commands |\thumbsoverview|, |\thumbsoverviewback|, |\thumbsoverviewverso|, and/or
% |\thumbsoverviewdouble| is/are used to place the overview page(s) for the thumb marks.
% Their single parameter is used to mark this page/these pages (e.\,g. in the page header).
% If these marks are not wished, |\thumbsoverview...{}| will generate empty marks in the
% page header(s). |\thumbsoverview| can be used more than once (for example at the
% beginning and at the end of the document, or |\thumbsoverview| at the beginning and
% |\thumbsoverviewback| at the end). The overviews have labels |TableOfThumbs1|,
% |TableOfThumbs2|, and so on, which can be referred to with e.\,g. |\pageref{TableOfThumbs1}|.
% The reference |TableOfThumbs| (without number) aims at the last used Table of Thumbs
% (for compatibility with older versions of this package).
% \begin{description}
% \item[-] |\thumbsoverview| prints the thumb marks at the right side
%            and (in |twoside| mode) skips left sides (useful e.\,g. at the beginning

%
% \item[-] |\thumbsoverviewverso| prints the thumb marks at the right side
%            and (in |twoside| mode) repeats them at the next left side and so on
%           (useful anywhere in the document and when one wants to prevent empty
%            pages)
%
% \item[-] |\thumbsoverviewdouble| prints the thumb marks at the left side

% \smallskip
%
% \subsubsection{\textbackslash thumbnewcolumn}
% \DescribeMacro{\thumbnewcolumn}
% With the command |\thumbnewcolumn| a new column can be started, even if the current one
% was not filled. This could be useful e.\,g. for a dictionary, which uses one column for
% translations from language A to language B, and the second column for translations
% from language B to language A. But in that case one probably should increase the
% size of the thumb marks, so that $26$~thumb marks (in~case of the Latin alphabet)
% fill one thumb column. Do not use |\thumbnewcolumn| on a page where |\addthumb| was
% already used, but use |\addthumb| immediately after |\thumbnewcolumn|.\\
%
% \subsubsection{\textbackslash addthumbsoverviewtocontents}
% \DescribeMacro{\addthumbsoverviewtocontents}
% |\addthumbsoverviewtocontents| with two arguments is a replacement for
% |\addcontentsline{toc}{<level>}{<text>}|, where the first argument of
% |\addthumbsoverviewtocontents| is for |<level>| and the second for |<text>|.
% If an entry of the thumbs mark overview shall be placed in the table of contents,
% |\addthumbsoverviewtocontents| with its arguments should be used immediately before
% |\thumbsoverview|.
%
% \subsubsection{\textbackslash thumbsnophantom}
% \DescribeMacro{\thumbsnophantom}
% When automatical placing of the |\phantomsection|s has \emph{not} been globally
% disabled by using option |nophantomsection| (see subsection~\ref{sss:nophantomsection}),
% it can be disabled just for the following thumb mark by the command |\thumbsnophantom|.

\section*{Example for thumbs}
\addcontentsline{toc}{section}{Example for thumbs}
\markboth{Example for thumbs}{Example for thumbs}

This example demonstrates the most common uses of package
\textsf{thumbs}, v1.0q as of 2014/03/09 (HMM).
The used options were \texttt{thumblink=rule}, \texttt{linefill=dots},
\texttt{height=auto}, \texttt{minheight=\{47pt\}}, \texttt{width={auto}},
\texttt{distance=\{2mm\}}, \newline
\texttt{topthumbmargin=\{auto\}}, \texttt{bottomthumbmargin=\{auto\}}, \newline
\texttt{eventxtindent=\{5pt\}}, \texttt{oddtxtexdent=\{5pt\}},
\texttt{evenmarkindent=\{0pt\}}, \texttt{oddmarkexdent=\{0pt\}},
\texttt{evenprintvoffset=\{0pt\}},
\texttt{nophantomsection=false},
\texttt{ignorehoffset=true}, \texttt{ignorevoffset=true}, \newline
\texttt{final=true},\texttt{hidethumbs=false}, and \texttt{verbose=true}.

\noindent These are the default options, except \texttt{verbose=true}.
For more details please see the documentation!\newline

\textbf{Hyperlinks or not:} If the \textsf{hyperref} package is loaded,
the references in the overview page for the thumb marks are also hyperlinked
(except when option \texttt{thumblink=none} is used).\newline

\bigskip

{\color{teal} Save per page about $200\unit{ml}$ water, $2\unit{g}$ CO$_{2}$
and $2\unit{g}$ wood:\newline
Therefore please print only if this is really necessary.}\newline

\bigskip

\textbf{%
For testing purpose page \pageref{greenpage} has been completely coloured!
\newline
Better exclude it from printing\ldots \newline}

\bigskip

Some thumb mark texts are too large for the thumb mark by intention
(especially when the paper size and therefore also the thumb mark size
is decreased). When option \texttt{width=\{autoauto\}} would be used,
the thumb mark width would be automatically increased.
Please see page~\pageref{HugeText} for details!

\bigskip

For printing this example to another format of paper (e.\,g. A4)
it is necessary to add the according option (e.\,g. \verb|a4paper|)
to the document class and recompile it! (In that case the
thumb marks column change will occur at another point, of course.)
With paper format equal to document format the document can be printed
without adapting the size, like e.\,g.
\textquotedblleft shrink to page\textquotedblright .
That would add a white border around the document
and by moving the thumb marks from the edge of the paper they no longer appear
at the side of the stack of paper. It is also necessary to use a printer
capable of printing up to the border of the sheet of paper. Alternatively
it is possible after the printing to cut the paper to the right size.
While performing this manually is probably quite cumbersome,
printing houses use paper, which is slightly larger than the
desired format, and afterwards cut it to format.

\newpage

\addtitlethumb{Frontmatter}{0}{white}{gray}{pagesLTS.0}

At the first page no thumb mark was used, but we want to begin with thumb marks
at the first page, therefore a
\begin{verbatim}
\addtitlethumb{Frontmatter}{0}{white}{gray}{pagesLTS.0}
\end{verbatim}
was used at the beginning of this page.

\newpage

\tableofcontents

\newpage

To include an overview page for the thumb marks,
\begin{verbatim}
\addthumbsoverviewtocontents{section}{Thumb marks overview}%
\thumbsoverview{Table of Thumbs}
\end{verbatim}
is used, where \verb|\addthumbsoverviewtocontents| adds the thumb
marks overview page to the table of contents.

\smallskip

Generally it is desirable to have a hyperlink from the thumbs overview page
to lead to the thumb mark and not to some earlier place. Therefore automatically
a \verb|\phantomsection| is placed before each thumb mark. But for example when
using the thumb mark after a \verb|\chapter{...}| command, it is probably nicer
to have the link point at the top of that chapter's title (instead of the line
below it). The automatical placing of the \verb|\phantomsection| can be disabled
either globally by using option \texttt{nophantomsection}, or locally for the next
thumb mark by the command \verb|\thumbsnophantom|. (When disabled globally,
still manual use of \verb|\phantomsection| is possible.)

%    \end{macrocode}
% \pagebreak
%    \begin{macrocode}
\addthumbsoverviewtocontents{section}{Thumb marks overview}%
\thumbsoverview{Table of Thumbs}

That were the overview pages for the thumb marks.

\newpage

\section{The first section}
\addthumb{First section}{\space\Huge{\textbf{$1^ \textrm{st}$}}}{yellow}{green}

\begin{verbatim}
\addthumb{First section}{\space\Huge{\textbf{$1^ \textrm{st}$}}}{yellow}{green}
\end{verbatim}

A thumb mark is added for this section. The parameters are: title for the thumb mark,
the text to be displayed in the thumb mark (choose your own format),
the colour of the text in the thumb mark,
and the background colour of the thumb mark (parameters in this order).\newline

Now for some pages of \textquotedblleft content\textquotedblright\ldots

\lipsum[1]
\newpage

\section{The second section}
\addthumb{Second section}{\Huge{\textbf{\arabic{section}}}}{green}{yellow}

For this section, the text to be displayed in the thumb mark was set to
\begin{verbatim}
\Huge{\textbf{\arabic{section}}}
\end{verbatim}
i.\,e. the number of the section will be displayed (huge \& bold).\newline

Let us change the thumb mark on a page with an even number:

\newpage

\section{The third section}
\addthumb{Third section}{\Huge{\textbf{\arabic{section}}}}{blue}{red}

No problem!

And you do not need to have a section to add a thumb:

\newpage

\addthumb{Still third section}{\Huge{\textbf{\arabic{section}b}}}{red}{blue}

This is still the third section, but there is a new thumb mark.

On the other hand, you can even get rid of the thumb marks
for some page(s):

\newpage

\stopthumb

The command
\begin{verbatim}
\stopthumb
\end{verbatim}
was used here. Until another \verb|\addthumb| (with parameters) or
\begin{verbatim}
\continuethumb
\end{verbatim}
is used, there will be no more thumb marks.

\newpage

Still no thumb marks.

\newpage

Still no thumb marks.

\newpage

Still no thumb marks.

\newpage

\continuethumb

Thumb mark continued (unchanged).

\newpage

Thumb mark continued (unchanged).

\newpage

Time for another thumb,

\addthumb{Another heading}{Small text}{white}{black}

and another.

\addthumb{Huge Text paragraph}{\Huge{Huge\\ \ Text}}{yellow}{green}

\bigskip

\textquotedblleft {\Huge{Huge Text}}\textquotedblright\ is too large for
the thumb mark. When option \texttt{width=\{autoauto\}} would be used,
the thumb mark width would be automatically increased. Now the text is
either split over two lines (try \verb|Huge\\ \ Text| for another format)
or (in case \verb|Huge~Text| is used) is written over the border of the
thumb mark. When the text is too wide for the thumb mark and cannot
be split, \LaTeX{} might nevertheless place the text into the next line.
By this the text is placed too low. Adding a 
\hbox{\verb|\protect\vspace*{-| some lenght \verb|}|} to the text could help,
for example\\
\verb|\addthumb{Huge Text}{\protect\vspace*{-3pt}\Huge{Huge~Text}}...|.
\label{HugeText}

\addthumb{Huge Text}{\Huge{Huge~Text}}{red}{blue}

\addthumb{Huge Bold Text}{\Huge{\textbf{HBT}}}{black}{yellow}

When there is more than one thumb mark at one page, this is also no problem.

\section{xcolor}
\addthumb{xcolor}{\Huge{\textbf{xcolor}}}{magenta}{cyan}

It is probably a good idea to have a look at the \textsf{xcolor} package
and use other colours than used in this example.

(About automatically increasing the thumb mark width to the thumb mark text
width please see the note at page~\pageref{HugeText}.)

\newpage

\addthumb{A mark}{\Huge{\textbf{A}}}{lime}{darkgray}

I just need to add further thumb marks to get them reaching the bottom of the page.

Generally the vertical size of the thumb marks is set to the value given in the
height option. If it is \texttt{auto}, the size of the thumb marks is decreased,
so that they fit all on one page. But when they get smaller than \texttt{minheight},
instead of decreasing their size further, a~new thumbs column is started
(which will happen here).

\newpage

\addthumb{B mark}{\Huge{\textbf{B}}}{brown}{pink}

There! A new thumb column was started automatically!

\newpage

\addthumb{C mark}{\Huge{\textbf{C}}}{brown}{pink}

You can, of course, keep the colour for more than one thumb mark.

\newpage

\addthumb{$1/1.\,955\,83$\, EUR}{\Huge{\textbf{D}}}{orange}{violet}

I am just adding further thumb marks.

If you are curious why the thumb mark between
\textquotedblleft C mark\textquotedblright\ and \textquotedblleft E mark\textquotedblright\ has
not been named \textquotedblleft D mark\textquotedblright\ but
\textquotedblleft $1/1.\,955\,83$\, EUR\textquotedblright :

$1\unit{DM}=1\unit{D\ Mark}=1\unit{Deutsche\ Mark}$\newline
$=\frac{1}{1.\,955\,83}\,$\euro $\,=1/1.\,955\,83\unit{Euro}=1/1.\,955\,83\unit{EUR}$.

\newpage

Let us have a look at \verb|\thumbsoverviewverso|:

\addthumbsoverviewtocontents{section}{Table of Thumbs, verso mode}%
\thumbsoverviewverso{Table of Thumbs, verso mode}

\newpage

And, of course, also at \verb|\thumbsoverviewdouble|:

\addthumbsoverviewtocontents{section}{Table of Thumbs, double mode}%
\thumbsoverviewdouble{Table of Thumbs, double mode}

\newpage

\addthumb{E mark}{\Huge{\textbf{E}}}{lightgray}{black}

\addthumb{New thumb marks column}{\Huge{\textit{NC}}}{magenta}{black}

Some faulty pdf-viewer sometimes (for the same document!)

(The origin is 0 0, there is not much to be rounded;
for the other sides the $\unit{pt}$ are written as $\unit{bp}$ into
the pdf-file, i.\,e. the rule is too large by $72.27/72$, which
should cover also rounding errors.)

The thumb marks are also too large - on purpose! This has been done
to assure, that they cover the page up to its (paper) border,
therefore they are placed a little bit over the paper margin.

Now I red somewhere in the net (should have remembered to note the url),
that white margins are presented, whenever there is some object outside
of the page. Thus, it is a feature, not a bug?!
What I do not understand: The same document sometimes is presented
with white lines and sometimes without (same viewer, same PC).\newline
But at least it does not influence the printed version.

It is possible to use the Table of Thumbs more than once (for example
at the beginning and the end of the document) and to refer to them via e.\,g.
\verb|\pageref{TableOfThumbs1}, \pageref{TableOfThumbs2}|,... ,
here: page \pageref{TableOfThumbs1}, page \pageref{TableOfThumbs2},
and via e.\,g. \verb|\pageref{TableOfThumbs}| it is referred to the last used
Table of Thumbs (for compatibility with older package versions).
If there is only one Table of Thumbs, this one is also the last one, of course.
Here it is at page \pageref{TableOfThumbs}.\newline

Now let us have a look at \verb|\thumbsoverviewback|:

\addthumbsoverviewtocontents{section}{Table of Thumbs, back mode}%
\thumbsoverviewback{Table of Thumbs, back mode}

\newpage

Text can be placed after any of the Tables of Thumbs, of course.

%
% If your \TeX{}~distribution (\teTeX{}, \mikTeX{},\dots{}) relies on file name

%
% \subsection{Some details for the interested}
%
% \paragraph{Unpacking with \LaTeX{}.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip{} and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX{} for \docstrip{} (really,
% \docstrip{} does not need \LaTeX{}), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{thumbs.dtx}|
% \end{quote}
% Do not forget to quote the argument according to the demands
% of your shell.
%
% \paragraph{Generating the documentation.\label{GenDoc}}
% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
% the documentation. The process can be configured by a
% configuration file \xfile{ltxdoc.cfg}. For instance, put the following
% line into this file, if you want to have A4 as paper format:
% \begin{quote}
%   \verb|\PassOptionsToClass{a4paper}{article}|
% \end{quote}
%
% \noindent An example follows how to generate the
% documentation with \pdfLaTeX{}:
%
% \begin{quote}
%\begin{verbatim}
%pdflatex thumbs.dtx
%makeindex -s gind.ist thumbs.idx
%pdflatex thumbs.dtx
%makeindex -s gind.ist thumbs.idx
%pdflatex thumbs.dtx
%\end{verbatim}
% \end{quote}
%
% \subsection{Compiling the example}
%
% The example file, \textsf{thumbs-example.tex}, can be compiled via\\
% \indent |latex thumbs-example.tex|\\
% or (recommended)\\
% \indent |pdflatex thumbs-example.tex|\\
% and will need probably at least four~(!) compiler runs to get everything right.

% \begin{History}\label{History}
%   \begin{Version}{2010/04/01 v0.01 -- 2011/05/13 v0.46}
%     \item Diverse $\beta $-versions during the creation of this package.\\
%   \end{Version}
%   \begin{Version}{2011/05/14 v1.0a}
%     \item Upload to \url{http://www.ctan.org/pkg/thumbs}.
%   \end{Version}
%   \begin{Version}{2011/05/18 v1.0b}
%     \item When more than one thumb mark is places at one single page,
%             the variables containing the values (text, colour, backgroundcolour)
%             of those thumb marks are now created dynamically. Theoretically,
%             one can now have $2\,147\,483\,647$ thumb marks at one page instead of
%             six thumb marks (as with \xpackage{thumbs} version~1.0a),
%             but I am quite sure that some other limit will be reached before the
%             $2\,147\,483\,647^ \textrm{th} $ thumb mark.
%     \item Bug fix: When a document using the \xpackage{thumbs} package was compiled,
%             and the \xfile{.aux} and \xfile{.tmb} files were created, and the
%             \xfile{.tmb} file was deleted (or renamed or moved),
%             while the \xfile{.aux} file was not deleted (or renamed or moved),
%             and the document was compiled again, and the \xfile{.aux} file was
%             reused, then reading from the then empty \xfile{.tmb} file resulted
%             in an endless loop. Fixed.
%     \item Minor details.
%   \end{Version}
%   \begin{Version}{2011/05/20 v1.0c}
%     \item The thumb mark width is written to the \xfile{log} file (in |verbose| mode
%             only). The knowledge of the value could be helpful for the user,
%             when option |width={auto}| was used, and one wants the thumb marks to be
%             half as big, or with double width, or a little wider, or a little
%             smaller\ldots\ Also thumb marks' height, top thumb margin and bottom thumb
%             margin are given. Look for\\
%             |************** THUMB dimensions **************|\\
%             in the \xfile{log} file.
%     \item Bug fix: There was a\\
%             |  \advance\th@mbheighty-\th@mbsdistance|,\\
%             where\\
%             |  \advance\th@mbheighty-\th@mbsdistance|\\
%             |  \advance\th@mbheighty-\th@mbsdistance|\\
%             should have been, causing wrong thumb marks' height, thereby wrong number
%             of thumb marks per column, and thereby another endless loop. Fixed.
%     \item The \xpackage{ifthen} package is no longer required for the \xpackage{thumbs}
%             package, removed from its |\RequirePackage| entries.
%     \item The \xpackage{infwarerr} package is used for its |\@PackageInfoNoLine| command.
%     \item The \xpackage{warning} package is no longer used by the \xpackage{thumbs}
%             package, removed from its |\RequirePackage| entries. Instead,
%             the \xpackage{atveryend} package is used, because it is loaded anyway
%             when the \xpackage{hyperref} package is used.
%     \item Minor details.
%   \end{Version}
%   \begin{Version}{2011/05/26 v1.0d}
%     \item Bug fix: labels or index or glossary entries were gobbled for the thumb marks
%             overview page, but gobbling leaked to the rest of the document; fixed.
%     \item New option |silent|, complementary to old option |verbose|.
%     \item New option |draft| (and complementary option |final|), which
%             \textquotedblleft de-coloures\textquotedblright\ the thumb marks
%             and reduces their width to~$2\unit{pt}$.
%   \end{Version}
%   \begin{Version}{2011/06/02 v1.0e}
%     \item Gobbling of labels or index or glossary entries improved.
%     \item Dimension |\thumbsinfodimen| no longer needed.
%     \item Internal command |\thumbs@info| no longer needed, removed.
%     \item New value |autoauto| (not default!) for option |width|, setting the thumb marks
%             width to fit the widest thumb mark text.
%     \item When |width={autoauto}| is not used, a warning is issued, when the thumb marks
%             width is smaller than the thumb mark text.
%     \item Bug fix: Since version v1.0b as of 2011/05/18 the number of thumb marks at one
%             single page was no longer limited to six, but the example still stated this.
%             Fixed.
%     \item Minor details.
%   \end{Version}
%   \begin{Version}{2011/06/08 v1.0f}
%     \item Bug fix: |\th@mb@titlelabel| should be defined |\empty| at the beginning
%             of the package: fixed. (Bug reported by \textsc{Veronica Brandt}. Thanks!)
%     \item Bug fix: |\thumbs@distance| versus |\th@mbsdistance|: There should be only
%             two times |\thumbs@distance|, the value of option |distance|,
%             otherwise it should be the length |\th@mbsdistance|: fixed.
%             (Also this bug reported by \textsc{Veronica Brandt}. Thanks!)
%     \item |\hoffset| and |\voffset| are now ignored by default,
%             but can be regarded using the options |ignorehoffset=false|
%             and |ignorevoffset=false|.
%             (Pointed out again by \textsc{Veronica Brandt}. Thanks!)
%     \item Added to documentation: The package takes the dimensions |\AtBeginDocument|,
%             thus later the page dimensions should not be changed.
%             Now explicitly stated this in the documentation. |\paperwidth| changes
%             are probably possible.
%     \item Documentation and example now give a lot more details.
%     \item Changed diverse details.
%   \end{Version}
%   \begin{Version}{2011/06/24 v1.0g}
%     \item Bug fix: When \xpackage{hyperref} was \textit{not} used,
%             then some labels were not set at all~- fixed.
%     \item Bug fix: When more than one Table of Tumbs was created with the
%            |\thumbsoverview| command, there were some
%            |counter ... already defined|-errors~- fixed.
%     \item Bug fix: When more than one Table of Tumbs was created with the
%            |\thumbsoverview| command, there was a
%            |Label TableofTumbs multiply defined|-error and it was not possible
%            to refer to any but the last Table of Tumbs. Fixed with labels
%            |TableofTumbs1|, |TableofTumbs2|,\ldots\ (|TableofTumbs| still aims
%            at the last used Table of Thumbs for compatibility.)
%     \item Bug fix: Sometimes the thumb marks were stopped one page too early
%             before the Table of Thumbs~- fixed.
%     \item Some details changed.
%   \end{Version}
%   \begin{Version}{2011/08/08 v1.0h}
%     \item Replaced |\global\edef| by |\xdef|.
%     \item Now using the \xpackage{pagecolor} package. Empty thumb marks now
%             inherit their colour from the pages's background. Option |pagecolor|
%             is therefore obsolete.
%     \item The \xpackage{pagesLTS} package has been replaced by the
%             \xpackage{pageslts} package.
%     \item New kinds of thumb mark overview pages introduced additionally to
%             |\thumbsoverview|: |\thumbsoverviewback|, |\thumbsoverviewverso|,
%             and |\thumbsoverviewdouble|.
%     \item New option |hidethumbs=true| to hide thumb marks (and their
%             overview page(s)).
%     \item Option |ignorehoffset| did not work for the thumb marks overview page(s)~-
%             neither |true| nor |false|; fixed.
%     \item Changed a huge number of details.
%   \end{Version}
%   \begin{Version}{2011/08/22 v1.0i}
%     \item Hot fix: \TeX{} 2011/06/27 has changed |\enddocument| and
%             thus broken the |\AtVeryVeryEnd| command/hooking
%             of \xpackage{atveryend} package as of 2011/04/23, v1.7.
%             Version 2011/06/30, v1.8, fixed it, but this version was not available
%             at \url{CTAN.org} yet. Until then |\AtEndAfterFileList| was used.
%   \end{Version}
%   \begin{Version}{2011/10/19 v1.0j}
%     \item Changed some Warnings into Infos (as suggested by \textsc{Martin Baute}).
%     \item The SW(P)-warning is now only given |\IfFileExists{tcilatex.tex}|,
%             otherwise just a message is given. (Warning questioned by
%             \textsc{Martin Baute}, thanks.)
%     \item New option |nophantomsection| to \emph{globally} disable the automatical
%             placement of a |\phantomsection| before \emph{all} thumb marks.
%     \item New command |\thumbsnophantom| to \emph{locally} disable the automatical
%             placement of a |\phantomsection| before the \emph{next} thumb mark.
%     \item README fixed.
%     \item Minor details changed.
%   \end{Version}
%   \begin{Version}{2012/01/01 v1.0k}
%     \item Bugfix: Wrong installation path given in the documentation, fixed.
%     \item No longer uses the |th@mbs@tmpA| counter but uses |\@tempcnta| instead.
%     \item No longer abuses the |\th@mbposyA| dimension but |\@tempdima|.
%     \item Update of documentation, README, and \xfile{dtx} internals.
%   \end{Version}
%   \begin{Version}{2012/01/07 v1.0l}
%     \item Bugfix: Used a |\@tempcnta| where a |\@tempdima| should have been.
%   \end{Version}
%   \begin{Version}{2012/02/23 v1.0m}
%     \item Bugfix: Replaced |\newcommand{\QTO}[2]{#2}| (for SWP) by
%             |\providecommand{\QTO}[2]{#2}|.
%     \item Bugfix: When the \xpackage{tikz} package was loaded before \xpackage{thumbs},
%             in |twoside|-mode the thumb marks were printed at the wrong side
%             of the page. (Bug reported by \textsc{Martin Baute}, thanks!) With
%             \xpackage{hyperref} it really depends on the loading order of the
%             three packages.
%     \item Now using |\ltx@ifpackageloaded| from the \xpackage{ltxcmds} package
%             to check (after |\begin{document}|) whether the \xpackage{hyperref}
%             package was loaded.
%     \item For the thumb marks |\parbox|es instead of |\makebox|es are used
%             (just in case somebody wants to place two lines into a thumb mark, e.\,g.\\
%             |Sch |\\
%             |St|\\
%             in a phone book, where the other |S|es are placed in another chapter).
%     \item Minor details changed.
%   \end{Version}
%   \begin{Version}{2012/02/25 v1.0n}
%     \item Check for loading order of \xpackage{tikz} and \xpackage{hyperref} replaced
%             by robust method. (Thanks to \textsc{David Carlisle}, 
%             \url{http://tex.stackexchange.com/a/45654/6865}!)
%     \item Fixed \texttt{url}-handling in the example in case the \xpackage{hyperref}
%           package was not loaded.
%     \item In the index the line-numbers of definitions were not underlined; fixed.
%     \item In the \xfile{thumbs-example} there are now a few words about
%             \textquotedblleft paragraph-thumbs\textquotedblright{}
%             (i.\,e.~text which is too long for the width of a thumb mark).
%   \end{Version}
%   \begin{Version}{2013/08/22 v1.0o, not released to the general public}
%     \item \textsc{Stephanie Hein} requested the feature to be able to increase
%             the horizontal space between page edge and the text inside of the
%             thumb mark. Therefore options |evenindent| and |oddexdent| were 
%             implemented (later renamed to |eventxtindent| and |oddtxtexdent|).
%     \item \textsc{Bjorn Victor} reported the same problem and also the one,
%             that two marks are not printed at the exact same vertical position
%             on recto and verso pages. Because this can be seen with a lot of
%             duplex printers, the new option |evenprintvoffset| allows to
%             vertically shift the marks on even pages by any length.
%   \end{Version}
%   \begin{Version}{2013/09/17 v1.0p, not released to the general public}
%     \item The thumb mark text is now set in |\parbox|es everywhere.
%     \item \textsc{Heini Geiring} requested the feature to be able to
%             horizontally move the marks away from the page edge,
%             because this is useful when using brochure printing
%             where after the printing the physical page edge is changed
%             by cutting the paper. Therefore the options |evenmarkindent| and
%             |oddmarkexdent| were introduced and the options |evenindent| and
%             |oddexdent| were renamed to |eventxtindent| and |oddtxtexdent|.
%     \item Changed a lot of internal details.
%   \end{Version}
%   \begin{Version}{2014/03/09 v1.0q}
%     \item New version of the \xpackage{atveryend} package is now available at
%             \url{CTAN.org} (see entry in this history for
%             \xpackage{thumbs} version |[2011/08/22 v1.0i]|).
%     \item Support for SW(P) drastically reduced. No more testing is performed.
%             Get a current \TeX{} distribution instead!
%     \item New option |txtcentered|: If it is set to |true|,
%             the thumb's text is placed using |\centering|,
%             otherwise either |\raggedright| or |\raggedleft|
%             (depending on left or right page for double sided documents).
%     \item |\normalsize| added to prevent 
%             \textquotedblleft font size leakage\textquotedblright{} 
%             from the respective page.
%     \item Handling of obsolete options (mainly from version 2013/08/22 v1.0o)
%             added.
%     \item Changed (hopefully improved) a lot of details.
%   \end{Version}
