+% \section{Introduction}\label{intro}
+% The \menukeys package is mainly designed to parse and print
+% sequences of software menus, folders and files or keystrokes.
+% The most predefined styles use the power of \TikZ\footnote{See
+% \url{http://www.ctan.org/pkg/pgf}.} to format the output.
+% 
+% For example if you want to tell the reader of a manual how to set the ruler
+% unit you may type
+% \begin{verbatim}
+%    To set the unit of the rulers go to \menu{Extras > Settings > Rulers}
+%    and choose between millimeters, inches and pixels. The shortcut
+%    to view the rulers is \keys{cmd + R}. Pressing these keys again
+%    will hide the rulers.
+%    
+%    The standard path for saving your document is \directory{Macintosh HD/Users/
+%    Your Name/Documents} but you can change it at \menu{Extras > Settings
+%    > Saving} by clicking \menu{Change save path}.
+% \end{verbatim}
+% and get this:

+% \medskip
+%    To set the unit of the rulers go to \menu{Extras > Settings > Rulers}
+%    and choose between millimeters, inches and pixels. The shortcut
+%    to view the rulers is \keys{cmd + R}. Pressing these keys again
+%    will hide the rulers.
+%    
+%    The standard path for saving your document is \directory{Macintosh HD/Users/
+%    Your Name/Documents} but you can change it at \menu{Extras > Settings
+%    > Saving} by clicking \menu{Change save path}.
+% 
+% \bigskip\noindent
+% The package is loaded as usual via
+% \begin{verbatim}
+%    \usepackage{menukeys}
+% \end{verbatim}
+% 
+% \section{Installation}
+% To install \menukeys manually run
+% \begin{verbatim}
+%    latex menukeys.ins
+% \end{verbatim}
+% and copy |menukeys.sty| to a path where \LaTeX{} can find it.
+% 
+% To typeset this manual run
+% \begin{verbatim}
+%    pdflatex menukeys.dtx
+%    makeindex -s gglo.ist -o menukeys.gls menukeys.glo
+%    makeindex -s gind.ist -o menukeys.ind menukeys.idx
+%    pdflatex menukeys.dtx
+%    pdflatex menukeys.dtx
+% \end{verbatim}
+%
+% \section{Package loading and options}\label{options}
+% Since \menukeys uses \pkg{catoptions}, which does some heavy changes on key-value
+% options, it is recommended to load \menukeys as the \textbf{last package}
+% (even after \pkg{hyperref}\footnote{See \url{http://tex.stackexchange.com/q/237683/4918}
+% and \url{https://github.com/tweh/menukeys/issues/41}.})!
+% 
+% These are the possible options:
+% \begin{description}
+%    \item [definemenumacros:] Most of \menukeys' macros should not
+%       conflict with other packages\footnote{If you find a conflict send an e-mail.}
+%       but the predefined menu macros should be short and easy-to-read
+%       commands, which means that |\menu{A,B,C}| is preferred against
+%       |\printmenusequence{A,B,C}|. For that it's not unlikely that they
+%       conflict with other packages. To prevent this you can tell
+%       \menukeys to not define them by calling the option \DO{definemenumacros}
+%       |definemenumacros=false|. The default value is |true|.
+%       
+%       If you do so you have to define your own menu macros, see section~\ref{menumacros}
+%       for details.
+%    \item [definekeys:] Equal to |definemenumacros|  \DO{definekeys}  for the key macros.
+%       The default value is |true|.
+%    \item [mackeys:] This option \DO{mackeys} allows you to decide whether the mac keys
+%       are shown as text (|mackeys=text|) or symbols  (|mackeys=symbols|). The default
+%       value is |symbols|.
+%    \item [os:] You can specify the OS \DO{os} by saying |os=mac| or |os=win|. This will cause
+%       some key macros to be rendered differently. The default value is |mac|.
+%    \item [hyperrefcolorlinks:] Use this if you want \pkg{hyperref}'s \DO{hyperrefcolorlinks}
+%       colored links, since you can't use the \pkg{hyperref} option \opt{colorlinks} directly
+%       (see sec.~\ref{sec:issues} and~\ref{sec:hyperref-colorlinks}).
+% \end{description}
+% 
+% \section{Usage}
+% \subsection{Basics}\label{basics}
+% \menukeys comes with three ``menu macros'' that parse and print lists. We have
+% \DM{\menu}|\menu|\marg{menu sequence}, with |>| as default input list separator,
+% \DM{\directory}|\directory|\marg{path and files} with |/| as default separator and
+% \DM{\keys}|\keys|\marg{keystrokes} with |+| as default separator. You've seen
+% examples for all of them in section~\ref{intro}.
+% 
+% These macros have also an optional argument to set the input list separator.
+% E.g. if you want to put in your menus with |,| instead of |>| you can say
+% |\menu[,]|\marg{menu sequence}.\footnote{If you want to change the input separator
+%  globally it's recommended to renew the menu macro as described in section~\ref{menumacros}.}
+% 
+% The possible input separators are |/|, |=|, |*|, |+|, |,|, |;|, |:|, |-|, |>|,
+% |<| and |bslash| (to use |\| as separator).  You can hide a separator from the
+% parser by putting a part of the sequence in braces. Spaces around the separator
+% will be ignored, i.e. |\keys{\ctrl+C}| equals |\keys{\ctrl + C}|.
+% \example |\menu[,]{Extras,Settings,{Units, rulers and origin}}| gives 
+% \menu[,]{Extras,Settings,{Units, rulers and origin}}
+%
+% \subsection{Styles}
+% \menukeys defines several ``styles'' that determine the output format
+% of a menu macro. There are some predefined styles and others can be
+% created by the user.
+% \subsubsection{Predefined styles}
+% 
+% \teststyle{menus}{File,Extras,Preferences}{Menu}
+% \teststyle{roundedmenus}{File,Extras,Preferences}{Menu}
+% \teststyle{angularmenus}{File,Extras,Preferences}{Menu}
+% \teststyle[The color of + is taken from optional color B.]
+%    {roundedkeys}{Ctrl,Alt,Q}{S}
+% \teststyle[The color of + is taken from optional color B.\\
+%    The shadow color is taken from optional color C.]
+%    {shadowedroundedkeys}{Ctrl,Alt,Q}{S}
+% \teststyle[The color of + is taken from optional color B.]
+%    {angularkeys}{Ctrl,Alt,Q}{S}
+% \teststyle[The color of + is taken from optional color B.\\
+%    The shadow color is taken from optional color C.]
+%    {shadowedangularkeys}{Ctrl,Alt,Q}{S}
+% \teststyle[The color of + is taken from optional color B.]
+%    {typewriterkeys}{Alt,Q}{S}
+% \teststyle[The sep color is taken from optional color C.]
+%    {paths}{C:,User,Folder,MyFile.tex}{MyFile.tex}
+% \teststyle[%
+%    The folder draw color is taken from optional color B.\\
+%    The folder fill color is taken from optional color A.\\
+%    The sep color is taken from optional color C.%
+%    ]
+%    {pathswithfolder}{C:,User,Folder,MyFile.tex}{MyFile.tex}
+% \teststyle[%
+%    The folder draw color is taken from optional color B.\\
+%    The folder fill color is taken from optional color C.\\
+%    The sep color is taken from optional color C.%
+%    ]
+%    {pathswithblackfolder}{C:,User,Folder,MyFile.tex}{MyFile.tex}
+% 
+% \bigskip\noindent
+% The following three styles allow paths elements to be hyphenated, but
+% they insert only a line break without a hyphen dash. Note that they only
+% work with |T1| and |OT1| encoding (at least I tested only these ones)
+% and that this in some cases doesn't work very well.
+% \teststyle[The sep color is taken from optional color C.]
+%    {hyphenatepaths}{C:,Database,User,ALongUserNameHere,%
+%    ALongerFolderNameAtThisPlace,MyFile.tex}{MyFile.tex}
+% \teststyle[%
+%    The folder draw color is taken from optional color B.\\
+%    The folder fill color is taken from optional color A.\\
+%    The sep color is taken from optional color C.%
+%    ]
+%    {hyphenatepathswithfolder}{C:,Database,User,ALongUserNameHere,%
+%    ALongerFolderNameAtThisPlace,MyFile.tex}{MyFile.tex}
+% \teststyle[%
+%    The folder draw color is taken from optional color B.\\
+%    The folder fill color is taken from optional color C.\\
+%    The sep color is taken from optional color C.%
+%    ]
+%    {hyphenatepathswithblackfolder}{C:,Database,User,ALongUserNameHere,%
+%    ALongerFolderNameAtThisPlace,MyFile.tex}{MyFile.tex}
+%
+% \bigskip\pagebreak
+% \minisec{Hint} The folder is drawn with the command \DM{\drawtikzfolder}
+% |\drawtikzfolder| which is part of \menukeys and has two optional arguments
+% to change the color of the lines and the fill color of the front:\\
+% |\drawtikzfolder|\oarg{front fill}\oarg{draw}
+% 
+% \subsubsection{Declaring styles}
+% The simplest way to define a new style is to use \DM{\newmenustylesimple}
+% |\newmenustylesimple|. It has six arguments: |\newmenustylesimple|\AST%
+% \marg{name}\oarg{pre}\marg{style}\oarg{sep}\oarg{post}\linebreak \marg{theme}
+% \begin{description}
+%    \item [name] is the name of the new style. It must follow the
+%       specifications of \TeX{} control sequences, which means it must
+%       contain only letters and no numbers.
+%    \item [pre] is the code which is executed before a menu macro.
+%    \item [style] is the style for the first list element. It has to be
+%       a \TikZ-style which is applied to a |node|, e.g. |draw,blue|.
+%    \item [sep] is the code executed between the lists elements, e.g. some
+%       space or a symbol.
+%    \item [post] is the code which is executed after a menu macro.
+%    \item [theme] is a color theme (see section~\ref{colors}).
+% \end{description}
+% \example Let us consider we want a list that prints a frame around its
+% elements and separates them by a star. We can use
+% \begin{verbatim}
+%    \newmenustylesimple{mystyle}{draw}[$\ast$]{mycolors}
+% \end{verbatim}
+% 
+% The more advanced command is \DM{\newmenustyle}|\newmenustyle|. It has
+% nine arguments: |\newmenustyle|\AST\marg{name}\oarg{pre}\marg{first}%
+% \oarg{sep}\marg{mid}\marg{last}\marg{single}\newline\oarg{post}\marg{theme}
+% \begin{description}
+%    \item [name] is the name of the new style. It must follow the
+%       specifications of \TeX{} control sequences, which means it must
+%       contain only letters and no numbers.
+%    \item [pre] is the code which is executed before a menu macro.
+%    \item [first] is the style for the first list element. It has to be
+%       a \TikZ-style which is applied to a |node|, e.g. |draw,blue|.
+%    \item [sep] is the code executed between the lists elements, e.g. some
+%       space or a symbol.
+%    \item [mid] is the style for all elements between the first and the
+%       last one. It has to be a \TikZ sytle.
+%    \item [last] is the style for the last list element.
+%       It has to be a \TikZ sytle.
+%    \item [single] this style is used if the list contains only one element.
+%       It has to be a \TikZ sytle.
+%    \item [post] is the code which is executed after a menu macro.
+%    \item [theme] is a color theme (see section~\ref{colors}).
+% \end{description}
+% \example We can extend the previous example and desire that the first and
+% the last element became red, and a single element should have a dashed frame. Furthermore
+% the menu sequence should be preceded  and followed by a bullet point:
+% \begin{verbatim}
+%    \newmenustyle{mystyle}[$\bullet$]{draw,red}[$\ast$]%
+%       {draw}{draw,red}{draw,dashed}[$\bullet$]
+% \end{verbatim}
+% 
+% If the \TikZ |node| system doesn't fit your needs there are the \textbf{starred versions}:
+% Use them and the arguments \meta{first}, 
+% \meta{mid}, \meta{last}, \meta{single} can be any \LaTeX{} code. To access the
+% current list element use \DM{\CurrentMenuElement}|\CurrentMenuElement|.
+% \example consider that we want all menu elements simple be fat and not
+% drawn with a \TikZ |node|. The separator should be the star again:
+% \begin{verbatim}
+%    \newmenustylesimple*{mystyle}{\textbf{\CurrentMenuElement}}[$\ast$]
+% \end{verbatim}
+%
+% If you want to make your own style you must take care of using the color
+% theme. \DM{\usemenucolor} To access a color of the currently applied
+% theme while defining a style use |\usemenucolor|\marg{element} (See 
+% section~\ref{colors} for details about possible elements).
+% 
+% \subsubsection{Copying styles}
+% To copy an existing style to a new style use \DM{\copymenustyle}|\copymenustyle|%
+% \marg{copy}\marg{original}.
+% \example To copy the definition of |mystyle| to |mycopy| use
+% \begin{verbatim}
+%    \copymenustyle{mycopy}{mystyle}
+% \end{verbatim}
+% 
+% \subsubsection{Changing styles}
+% The simplest change we can imagine is to change a single element or the color theme of
+% an existing style. For the first case there is \DM{\changemenuelement}
+% |\changemenuelement|\AST\marg{name} \marg{element}\marg{definition}, where the starred
+% version works like the one of |\newmenustyle| does.
+% \example To change the single element of |mystyle| from dashed to solid use the
+% following code. You may save the original style by copying it as described above.
+% \begin{verbatim}
+%    \changemenuelement{mystyle}{single}{draw}
+% \end{verbatim}
+% \DM{\changemenucolortheme}To satisfy the second case use |\changemenucolortheme|%
+% \marg{name}\marg{color theme}.
+% \example To change the color theme of |mystyle| to |myothercolors| call
+% \begin{verbatim}
+%    \changemenucolortheme{mystyle}{myothercolors}
+% \end{verbatim}
+% 
+% \DM{\renewmenustylesimple}\DM{\providemenustylesimple}\DM{\renewmenustyle}%
+% \DM{\providemenustyle} The next level is redefining a style. This package provides
+% the following  macros the work like their \LaTeX-paragons and have the same
+% arguments as the above described macros: |\renewmenustylesimple|,
+% |\providemenustylesimple|, |\renewmenustyle| and |\providemenustyle|.
+%
+% \subsection{Color themes}\label{colors}%
+% To make the colors of a style become changeable without
+% touching the style itself, \menukeys uses ``color themes''. Every color theme
+% must contain three color definitions that can be used to draw a |node| 
+% background, a |node| frame and a text color, and additionally two optional
+% colors used by some themes.
+% \subsubsection{Predefined themes}
+% There are two predefined color themes
+% \colortest{gray}\colortest{blacknwhite}
+% \subsubsection{Create a theme}
+% \DM{\newmenucolortheme}To create a new theme use |\newmenucolortheme|. It uses the
+% following arguments:\\
+% |\newmenucolortheme|\marg{name}\marg{model}\marg{bg}\marg{br}\marg{txt}\oarg{a}\oarg{b}\oarg{c}
+% \begin{description}
+%    \item [name] is the name of the theme and must contain only letters.
+%    \item [model] is the \pkg{xcolor} color model which is used to define a color, e.g.
+%       |named|, |rgb|, |cmyk|, \dots
+%    \item [bg] is the color definition for the |node| background.
+%    \item [br] is the color definition for the |node| border.
+%    \item [txt] is the color definition for the |node|'s text.
+%    \item [a] is an optional additional color (by default same as bg).
+%    \item [b] is an optional additional color (by default same as br).
+%    \item [c] is an optional additional color (by default same as txt).
+% \end{description}
+% \example To create a theme called |mycolors| we can say
+% \begin{verbatim}
+%    \newmenucolortheme{mycolors}{named}{red}{green}{blue}
+% \end{verbatim}
+% \subsubsection{Copy a theme}
+% \DM{\copymenucolortheme}To copy the definitions of one theme to another,
+% use |\copymenucolortheme| \marg{copy}\marg{original}.
+% \example To copy the colors of |mycolors| to |copycolors| type
+% \begin{verbatim}
+%    \copymenucolortheme{copycolors}{mycolors}
+% \end{verbatim}
+% \subsubsection{Change a theme}
+% \DM{\changemenucolor} If you want to change the color of a theme's element
+% use |\changemenucolor|\marg{name} \marg{element}\marg{model}\marg{color definition},
+% where name is the theme's name and \meta{element} is |bg|, |br|, or |txt|.
+% \example Let's change the text color of |mycolors|:
+% \begin{verbatim}
+%    \changemenucolor{mycolors}{txt}{named}{gray}
+% \end{verbatim}
+% 
+% \DM{\renewmenucolortheme}To redefine a complete theme use |\renewmenucolortheme|.
+% It works with the same arguments as |\newmenucolortheme|.
+%
+% \subsection{Menu macros}\label{menumacros}%
+% The ``menu marcos'' take a list separated by a special symbol to
+% print it with a menu style.
+% \subsubsection{Predefined menu macros}
+% See section~\ref{basics}.
+% \subsubsection{Defining or changing menu macros}
+% \DM{\newmenumacro}To define a new menu macro call |\newmenumacro|\marg{macro}%
+% \oarg{input sep}\marg{style}.
+% \begin{description}
+%    \item [name] is a \LaTeX{} control sequence name.
+%    \item [input sep] is the default separator used in the input list 
+%       (see section~\ref{basics} for a list of valid separators).
+%    
+%       If you don't give it the package's default (|,|) is used.
+%    \item [style] is a menu style.
+% \end{description}
+% This wil give you a macro like |\|\meta{macro}\oarg{input sep}\marg{list}
+% \example Assuming you need a command to format Windows paths, you can
+% define it with
+% \begin{verbatim}
+%    \newmenumacro{\winpath}[bslash]{mystyle}
+% \end{verbatim}
+% and then use it as e.g. |\winpath{C:\System\Deep\Deeper\YourFile.txt}|.
+% Note that |mystyle| must be defined before you call |\newmenumacro|.
+% 
+% \DM{\providemenumacro}\DM{\renewmenumacro}There are also the two commands
+% |\providemenumacro| and |\renewmenumacro| which take the same arguments as
+% |\newmenumacro| and work like the \LaTeX{} macros |\renewcommand| and |\providecommand|.
+% \example To change the default input separator of |\menu| you must know
+% the default style (which is |menus|) and then you can say
+% \begin{verbatim}
+%    \renewmenumacro{\menu}[,]{menus}
+% \end{verbatim}
+%
+% \subsection{Keys}
+% The \menukeys package comes with some macros to print
+% special keys in the sequences set with |\keys|. Depending on
+% the given OS (see section~\ref{options}) some macros behave
+% differently to be able to use a key even if it's undefined
+% via the \opt{os} option macros like |\|\meta{key}|mac| and
+% |\|\meta{key}|win| that will always give the right symbol.
+%
+% The full ist of key macros is shown in table~\ref{tab:keys}.
+%
+% \begin{table}[ht]

+%     \hline
+%  \end{tabular}
+%  \end{minipage}
+% \end{table}
+%
+% \DM{\arrowkey}
+% The macro |\arrowkey|\marg{direction} is a little special
+% since it takes the direction as a singe character |^|, |v|
+% (lower case v), |>| or |<|.
+% 
+% \DM{\ctrlname}\DM{\delname}\DM{\spacename}The texts for |\ctrl|, 
+% |\del| and |\SPACE| are saved in |\ctrlname|, |\delname|, |\spacename| respectively.
+% So you can change them with |\renewcommand|.
+% 
+% The rendering of some Mac macros depend on the option \DO{mackeys}\opt{mackeys}
+% The different versions are shown in the table (left: |text|, right: |symbols|).
+%

+% I apologize that there are no commands for the windows key
+% and the apple logo, but that would be a copyright infringement.
+% 
+% \section{Known issues and bugs}\label{sec:issues}
+% \begin{itemize}
+%    \item If you use the \pkg{inputenc} package \menukeys must be
+%       loaded after it. Otherwise some key macros get corrupted.
+%    \item \changes{v1.1}{2012/02/26}{Load \pkg{xcolor} before \menukeys.}
+%       \menukeys must be loaded after \pkg{xcolor}, if you load
+%       the latter with options. Otherwise you'll get an option clash
+%       Since \menukeys loads \pkg{xcolor} internally you may pass
+%       options as global options via |\documentclass|.
+%       \example Set \pkg{xcolor} to |cmyk| model:
+%       \begin{verbatim}
+%    \documentclass[cmyk]{article}
+%    \usepackage{menukeys}
+%    \begin{document}
+%       Hello World!
+%    \end{document}
+%    \end{verbatim}
+%   \item Using \pkg{hyperref} with the \opt{colorlinks} options causes
+%      an option clash. If you want colored links please load \pkg{hyperref}
+%      \emph{without} this option and load \pkg{menukeys} with \opt{hyperrefcolorlinks}.
+% \end{itemize}
+%
+% If you find something to add to this list please send me an e-mail or report a
+% bug on GitHub (\url{https://github.com/tweh/menukeys}).

+% \section{Implementation}
+% \subsection{Required packages}
+% Load the required packages
+%    \begin{macrocode}
+\RequirePackage{xparse}
+\RequirePackage{xstring}
+\RequirePackage{etoolbox}
+%    \end{macrocode}
+% Furthermore we need \TikZ and some of its libraries,
+%    \begin{macrocode}
+\RequirePackage{tikz}
+   \usetikzlibrary{calc,shapes.symbols,shadows}
+%    \end{macrocode}
+% the color package \pkg{xcolor} and \pkg{adjustbox} for the
+% |typewriterkeys| style.
+%    \begin{macrocode}
+\RequirePackage{xcolor}
+\RequirePackage{adjustbox}
+%    \end{macrocode}
+% Load \pkg{relsize} to be able to change the font size
+% relative to the surrounding text.
+%    \begin{macrocode}
+\RequirePackage{relsize}
+%    \end{macrocode}
+% To define the list parsing commands and allow |\| as
+% a separator we load \pkg{catoptions}
+%    \begin{macrocode}
+\RequirePackage{catoptions}[2011/12/07]
+%    \end{macrocode}
+%
+% \subsection{Helper macros}
+% \begin{macro}{\tw@mk@error}\begin{macro}{\tw@mk@warning}
+% \begin{macro}{\tw@mk@warning@noline}
+% Define macros to call |\PackageError| and warnings
+%    \begin{macrocode}
+\newcommand*{\tw@mk@error}[2][Please consult the manual for more information.]{%
+   \PackageError{menukeys}{#2}{#1}%
+}
+\newcommand*{\tw@mk@warning}[1]{%
+   \PackageWarning{menukeys}{#1}%
+}
+\newcommand*{\tw@mk@warning@noline}[1]{%
+   \PackageWarningNoLine{menukeys}{#1}%
+}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+% \begin{macro}{\tw@mk@tempa}\begin{macro}{\tw@mk@tempb}
+% Some commands for temporary use:
+%    \begin{macrocode}
+\def\tw@mk@tempa{}
+\def\tw@mk@tempb{}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% \begin{macro}{\tw@mk@gobble@args}
+% Define a command to gobble arguments.
+%    \begin{macrocode}
+\DeclareDocumentCommand{\tw@mk@gobble@args}{m}{%
+   \RenewDocumentCommand{\tw@mk@tempa}{#1}{}%
+   \tw@mk@tempa%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Options}
+% First we declare and process the package options
+%    \begin{macrocode}
+\RequirePackage{kvoptions}
+\SetupKeyvalOptions{
+  family=tw@mk,
+  prefix=tw@mk@
+}
+\DeclareBoolOption[true]{definemenumacros}
+\DeclareBoolOption[true]{definekeys}
+\DeclareBoolOption[false]{hyperrefcolorlinks}
+\DeclareStringOption[mac]{os}
+\DeclareStringOption[symbols]{mackeys}
+\ProcessKeyvalOptions{tw@mk}\relax
+%    \end{macrocode}
+% Now we have to do some error treatment:
+%    \begin{macrocode}
+\IfSubStr{.mac.win.}{.\tw@mk@os.}{}{%
+   \tw@mk@error{Unknown value for option 'os'\MessageBreak
+   Possible values are 'mac' or 'win'.}%
+}
+\IfSubStr{.symbols.text.}{.\tw@mk@mackeys.}{}{%
+   \tw@mk@error{Unknown value for option 'mackeys'\MessageBreak
+   Possible values are 'symbols' or 'text'.}%
+}
+%    \end{macrocode}
+%
+% \subsection{Workarounds}
+% Some workarounds to ``slove'' some incompatibilities:
+% \subsubsection{\pkg{hyperref}'s \opt{colorlinks} option}\label{sec:hyperref-colorlinks}
+% \changes{v1.5}{2016/08/08}{New option \opt{hyperrefcolorlinks}}
+% Since the \opt{colorlinks} option of \pkg{hyperref} loads \pkg{color} (with
+% some kind of |\AtBeginDocument|) it results in an option clas due to the
+% changes made by \pkg{catoptions}. Thus one can't use \opt{colorlinks}. Here we
+% provide the code to activate colored links without the extra loading of
+% \pkg{color}.
+%    \begin{macrocode}
+\iftw@mk@hyperrefcolorlinks
+   \Hy@AtBeginDocument{%  (hyperref.sty, line 4790)
+       \def\@pdfborder{0 0 0}% (hyperref.sty, line 4806...)
+       \let\@pdfborderstyle\@empty
+%       \ifHy@typexml% <--------------+
+%       \else%                        | This part
+%         \Hy@CatcodeWrapper{%        | bust be

+       \def\Hy@endcolorlink{\endgroup}%
+       \Hy@Info{Link coloring ON}%
+   }
+\fi
+%    \end{macrocode}
+%
+% \subsection{Color themes}
+% \subsubsection{Internal commands}
+% \begin{macro}{\tw@make@color@theme}
+% First we define an internal command to make a color theme
+%    \begin{macrocode}
+\newcommand*{\tw@make@color@theme}[8]{%
+   \definecolor{tw@color@theme@#1@bg}{#2}{#3}%
+   \definecolor{tw@color@theme@#1@br}{#2}{#4}%
+   \definecolor{tw@color@theme@#1@txt}{#2}{#5}%
+   \definecolor{tw@color@theme@#1@a}{#2}{#6}%
+   \definecolor{tw@color@theme@#1@b}{#2}{#7}%
+   \definecolor{tw@color@theme@#1@c}{#2}{#8}%
+}
+%    \end{macrocode}
+% \end{macro}
+% \subsubsection{User-level commands}
+% \begin{macro}{\newmenucolortheme}\begin{macro}{\renewmenucolortheme}
+% After that we define the user-level commands:
+%    \begin{macrocode}
+\NewDocumentCommand{\newmenucolortheme}{ m m m m m O{#3} O{#4} O{#5} }{%
+   \@ifundefinedcolor{tw@color@theme@#1@bg}{%
+      \tw@make@color@theme{#1}{#2}{#3}{#4}{#5}{#6}{#7}{#8}%
+   }{%
+      \tw@mk@error{Color theme '#1' already defined!\MessageBreak
+      Use \string\renewmenucolortheme\space instead.}%
+   }
+}
+\NewDocumentCommand{\renewmenucolortheme}{ m m m m m O{#3} O{#4} O{#5} }{%
+   \tw@make@color@theme{#1}{#2}{#3}{#4}{#5}{#6}{#7}{#8}%
+}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% \begin{macro}{\changemenucolor}\begin{macro}{\copymenucolortheme}
+% Lastly we define the changing and copying commands
+%    \begin{macrocode}
+\newcommand*{\changemenucolor}[4]{%
+   \IfSubStr{ bg br txt }{ #2 }{%
+      \definecolor{tw@color@theme@#1@#2}{#3}{#4}%
+   }{%
+      \tw@mk@error{No such color element ('#2')!\MessageBreak
+      Possible values are bg, br and txt.}
+   }%
+}
+\newcommand*{\copymenucolortheme}[2]{%
+   \@ifundefinedcolor{tw@color@theme@#1@bg}{%
+      \colorlet{tw@color@theme@#1@bg}{tw@color@theme@#2@bg}%
+      \colorlet{tw@color@theme@#1@br}{tw@color@theme@#2@br}%
+      \colorlet{tw@color@theme@#1@txt}{tw@color@theme@#2@txt}%
+      \colorlet{tw@color@theme@#1@a}{tw@color@theme@#2@a}%
+      \colorlet{tw@color@theme@#1@b}{tw@color@theme@#2@b}%
+      \colorlet{tw@color@theme@#1@c}{tw@color@theme@#2@c}%
+   }{%
+      \tw@mk@error{Color theme '#1' already defined!\MessageBreak
+      Use \string\renewmenucolortheme\space instead.}
+   }
+}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% \begin{macro}{\changemenucolortheme}
+% To be able to change the color theme of a style we must define this:
+%    \begin{macrocode}
+\newcommand{\changemenucolortheme}[2]{%
+   \ifcsundef{tw@style@#1@pre}{%
+      \tw@mk@error{Style '#1' undefined!\MessageBreak
+      Maybe you misspelled it?}%
+   }{%
+      \@ifundefinedcolor{tw@color@theme@#2@bg}{%
+         \tw@mk@error{Color theme '#2' is not defined!}%
+      }{%
+         \csdef{tw@style@#1@color@theme}{#2}%
+      }%
+   }%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\usemenucolor}
+% To use a color of a theme we define |\usemenucolor| as following.
+%    \begin{macrocode}
+\newcommand{\usemenucolor}[1]{%
+   tw@color@theme@\tw@current@color@theme @#1%
+}
+%    \end{macrocode}
+% \end{macro}
+% \subsubsection{Predefined themes}
+% There are two predefined color themes
+%    \begin{macrocode}
+\newmenucolortheme{gray}{gray}{0.95}{0.3}{0}[0.95][0][0]
+\newmenucolortheme{blacknwhite}{gray}{1}{0}{0}[1][0][0]
+%    \end{macrocode}
+% \subsection{Styles}
+% The style generating commands will set some commands that are named
+% like |\tw@style@|\meta{name}|@|\meta{element}.
+% \begin{macro}{\tw@default@sep}
+% \begin{macro}{\tw@default@pre}
+% \begin{macro}{\tw@default@post}
+% Before we can define the internal
+% declaring macro to use it later in the user level commands, we have to set
+% some defaults for the optional arguments
+%    \begin{macrocode}
+\newcommand{\tw@default@sep}{%
+   \hspace{0.2em plus 0.1em minus 0.5em}%
+}
+\newcommand{\tw@default@pre}{}
+\newcommand{\tw@default@post}{}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+% \subsubsection{Internal commands}
+% Now we can define the internal commands.
+% \begin{macro}{\tw@declare@style@simple}
+% Our first step is to define the simple command.
+%    \begin{macrocode}
+\DeclareDocumentCommand{\tw@declare@style@simple}{%
+   s m O{\tw@default@pre} m O{\tw@default@sep} O{\tw@default@post} m

+   \IfBooleanTF{#1}{%
+      \csdef{tw@style@#2@single}{#4}%
+      \csdef{tw@style@#2@first}{#4}%
+      \csdef{tw@style@#2@mid}{#4}%
+      \csdef{tw@style@#2@last}{#4}%
+   }{%
+      \csdef{tw@style@#2@single}{%
+         \tikz[baseline=(tw@node.base)]{%

+      \csdef{tw@style@#2@first}{%

+         \tikz[baseline=(tw@node.base)]{%
+         \node(tw@node)[#4]{\strut\CurrentMenuElement};}}%
+   }%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\tw@declare@sytle}\begin{macro}{\tw@declare@sytle@extra@args}
+% The next step is to create the extended command. This command must have
+% ten arguments (including the star) so we have to define a helping macro
+% to grab the last two macros.
+%    \begin{macrocode}
+\DeclareDocumentCommand{\tw@declare@sytle@extra@args}{%
+   O{\tw@default@post} m

+   \csdef{tw@style@\tw@current@style @post}{#1}%
+   \csdef{tw@style@\tw@current@style @color@theme}{#2}%
+}
+%    \end{macrocode}
+% Now we can define |\tw@declare@style|:
+%    \begin{macrocode}

+   \IfBooleanTF{#1}{%
+      \csdef{tw@style@#2@single}{#8}%
+      \csdef{tw@style@#2@first}{#4}%
+      \csdef{tw@style@#2@mid}{#6}%
+      \csdef{tw@style@#2@last}{#7}%
+   }{%
+      \csdef{tw@style@#2@single}{%
+         \tikz[baseline=(tw@node.base)]{%

+      \csdef{tw@style@#2@first}{%
+         \tikz[baseline=(tw@node.base)]{%
+         \node(tw@node)[#4]{\strut\CurrentMenuElement};}}%
+      \csdef{tw@style@#2@mid}{%

+   }%
+   \tw@declare@sytle@extra@args%
+}
+%    \end{macrocode}
+% \end{macro}\end{macro}
+% \subsubsection{User-level commands}

+% \begin{macro}{\copymenustyle}
+% The last two steps in this part are to define a command to copy

+% \subsubsection{Predefined styles}
+% We define several styles for menu sequences, paths and keystrokes.
+% \begin{macro}{tw@set@tikz@colors}

+% everything directly to the |node|s.

+% \begin{macro}{\renewmenumacro}
+% \begin{macro}{\providemenumacro}
+% Now it's time to build the user-level commands
+%    \begin{macrocode}
+\NewDocumentCommand{\newmenumacro}{m O{\tw@default@input@sep} m}{%
+   \ifcsundef{\expandafter\@gobble\string#1}{%
+      \tw@define@menu@macro{#1}[#2]{#3}%

+   }%
+}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+%
+% \subsubsection{Predefined menu macros}
+% Now we got all tools to predefine some menu macros. To be sure that
+% these commands won't conflict with other packages we introduced the
+% option |definemacros|. Here we have to check it:
+%    \begin{macrocode}
+\iftw@mk@definemenumacros
+%    \end{macrocode}
+% \begin{macro}{\menu}\begin{macro}{\directory}%
+% \changes{v1.1}{2012/02/27}{Renamed \cmd{\path} to \cmd{\directory} because it
+%    crashes with \pkg{biblatex}}
+% \begin{macro}{\keys}
+% And then we define three basic macros.
+%    \begin{macrocode}
+\newmenumacro{\menu}[>]{menus}
+\newmenumacro{\directory}[/]{paths}
+\newmenumacro{\keys}[+]{roundedkeys}
+%    \end{macrocode}
+% \end{macro}\end{macro}\end{macro}
+% Lastly we close the |definemacros| if statement:
+%    \begin{macrocode}
+\fi
+%    \end{macrocode}
+%
+% \subsection{Keys}
+% Before we define anything we check if the user allows it:
+%    \begin{macrocode}
+\iftw@mk@definekeys
+%    \end{macrocode}
+%
+% Before define the key macros we create some macros that save some typing by
+% condensing the similarities between the key macros.
+% \begin{macro}{\tw@make@key@box}
+% The first of these macros helps us building save boxes
+% to store the |{tikzpicture}|, that will draw the key later.
+% This is necessary because otherwise the picture will inherit
+% the style of the key sequence |node|.
+%    \begin{macrocode}
+\NewDocumentCommand{\tw@make@key@box}{m m}{%
+%   \expandafter\newbox\csname tw@mk@box@#1\endcsname
+%   \expandafter\sbox\csname tw@mk@box@#1\endcsname{%
+%      #2%
+%   }%
+   \csdef{tw@mk@#1}{%
+%      \expandafter\usebox\csname tw@mk@box@#1\endcsname%
+      #2%
+   }%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\tw@make@key@macro}
+% The next macro defines the user level command by accessing a
+% macro like |tw@mk@|\meta{key} or |tw@mk@|\meta{key}|@|\meta{os},
+% if the appearance differs between Mac and Windows.
+% To use this macro we assume that the |tw@mk@|\meta{key} commands
+% are defined.
+%    \begin{macrocode}
+\NewDocumentCommand{\tw@make@key@macro}{s m}{%
+   \IfBooleanTF{#1}{%
+      \expandafter\providecommand\csname\expandafter\@gobble\string#2\endcsname{%
+         \expandonce{\maxsizebox{!}{1.8ex}{%
+            \@nameuse{tw@mk@\expandafter\@gobble\string#2@\tw@mk@os}}%
+         }%
+      }%
+      \expandafter\providecommand\csname\expandafter\@gobble\string#2mac\endcsname{%
+         \expandonce{\maxsizebox{!}{1.8ex}{%
+            \@nameuse{tw@mk@\expandafter\@gobble\string#2@mac}}%
+         }%
+      }%
+      \expandafter\providecommand\csname\expandafter\@gobble\string#2win\endcsname{%
+         \expandonce{\maxsizebox{!}{1.8ex}{%
+            \@nameuse{tw@mk@\expandafter\@gobble\string#2@win}}%
+         }%
+      }%
+   }{%
+      \expandafter\providecommand\csname\expandafter\@gobble\string#2\endcsname{%
+         \expandonce{\maxsizebox{!}{1.8ex}{%
+            \@nameuse{tw@mk@\expandafter\@gobble\string#2}}%
+         }%
+      }%
+   }%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\tw@define@mackey}
+% The last helping macro is |\tw@define@mackey|. We use it to execute
+% code depending on the |mackeys| option.
+%    \begin{macrocode}
+\newcommand*{\tw@define@mackey}[2]{%
+   \IfStrEq{text}{\tw@mk@mackeys}{#1}{%
+      \IfStrEq{symbols}{\tw@mk@mackeys}{#2}{}%
+   }%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% Next thing to do is to set up some \TikZ-styles.
+%    \begin{macrocode}
+\tikzset{
+   menukeys key symbol/.style={
+      rounded corners=0pt,
+      line width=0.1ex,
+      baseline={(0,0)},
+   },
+   menukeys thick/.style={line width=0.25ex},
+}
+%    \end{macrocode}
+%
+% Now we ar prepared to generate the key macros. I will be nearly the same
+% way for all keys. Step one is to build a |tw@mk@|\meta{key} macro
+% and then we define the user-level command |\|\meta{key}
+% \begin{macro}{\shift}
+%    \begin{macrocode}
+\normalsize
+\tw@make@key@box{shift}{%
+   \begin{tikzpicture}[yshift=-0.1ex,menukeys key symbol]
+      \draw (0.3ex,0) -- (1.1ex,0) -- (1.1ex,1.2ex) -- %
+            (1.5ex,1.2ex) -- (0.7ex,1.9ex) -- (-0.1ex,1.2ex) -- %
+            (0.3ex,1.2ex) -- cycle;
+   \end{tikzpicture}%
+}
+\tw@make@key@macro{\shift}
+%    \end{macrocode}
+% \end{macro}
+% It's a little more complicated if the appearance should differ depending on the
+% OS: The first step again is to define |tw@mk@|\meta{key}|@mac| and
+% |tw@mk@|\meta{key}|@win|. And then use the starred version
+% |\tw@make@key@macro*| which creates |\|\meta{key} that depends on the |os|
+% option, |\|\meta{key}|mac| and |\|\meta{key}|win|, that are not affected by
+% |os|.
+% \begin{macro}{\capslock}
+%    \begin{macrocode}
+\tw@make@key@box{capslock@mac}{%
+   \begin{tikzpicture}[yshift=-0.1ex,menukeys key symbol]
+      \draw (0.3ex,0.7ex) -- (1.1ex,0.7ex) -- (1.1ex,1.2ex) -- %
+            (1.5ex,1.2ex) -- (0.7ex,1.9ex) -- (-0.1ex,1.2ex) -- %
+            (0.3ex,1.2ex) -- cycle;
+      \draw (0.3ex,0) rectangle (1.1ex,0.4ex);
+   \end{tikzpicture}%
+}
+\tw@make@key@box{capslock@win}{%
+   \begin{tikzpicture}[yscale=-1,yshift=-1.8ex,menukeys key symbol]
+      \draw (0.3ex,0) -- (1.1ex,0) -- (1.1ex,1.2ex) -- %
+            (1.5ex,1.2ex) -- (0.7ex,1.9ex) -- (-0.1ex,1.2ex) -- %
