将按键包中的项目居中对齐

Question

我正在使用 keystroke 包来创建键盘图标。但是，其中几个项目没有居中对齐。例如，单个数字全部右对齐，这让按钮看起来很奇怪。我该如何解决这个问题？

梅威瑟：

\documentclass[12pt]{report}

\usepackage{keystroke}


\begin{document}
    
    \begin{itemize}
        \item \keystroke{0},\keystroke{1} ...\keystroke{9}: The digits 0 through to 9.
        \item \keystroke{+}: Addition
        \item \keystroke{$-$}: Subtraction
        \item \keystroke{$*$}: Multiplication
        \item \keystroke{$/$}: Division
    \end{itemize}
    
\end{document}

Answer 1

尝试这个：

\documentclass[12pt]{report}

\usepackage{keystroke}
\usepackage{xpatch}

\makeatletter
\xpatchcmd\suse@keystr@ke
  {\hbox to 0pt{\unhbox\suse@key\hss}}
  % \suse@key = \hbox{{\keystroke@font\strut#1}}
  % \@tempdimb = max(\wd\suse@key, \dp\suse@key)
  {\hbox to 0pt{\hbox to \@tempdimb{\hss\unhbox\suse@key\hss}\hss}}
  {}{\PatchFailed}
\makeatother


\begin{document}
    
    \begin{itemize}
        \item \keystroke{0},\keystroke{1} ...\keystroke{9}: The digits 0 through to 9.
        \item \keystroke{+}: Addition
        \item \keystroke{$-$}: Subtraction
        \item \keystroke{$*$}: Multiplication
        \item \keystroke{$/$}: Division
    \end{itemize}
    
\end{document}

Answer 2

这段代码很棘手，但是有效！

\documentclass[12pt]{report}

\usepackage{keystroke}


\begin{document}
    
    \begin{itemize}
        \item \keystroke{\,0},\keystroke{\,1} ...\keystroke{\,9}: The digits 0 through to 9.
        \item \keystroke{+}: Addition
        \item \keystroke{$-$}: Subtraction
        \item \keystroke{$\,*$}: Multiplication
        \item \keystroke{$\,/$}: Division
    \end{itemize}
    
\end{document}

或者，您必须在包实现中做出一些编辑。
