Beamer：定理中的“字幕”

在我的文档中，我目前正在使用paragraph我的定理创建“子标题”。

在序言中：

\usepackage{amsthm}
\newtheorem{deff}{Definition}

在文档中：

\begin{deff}

A recipe is 

\paragraph{given}
\begin{enumerate}
\item a desired outcome
\item a language of instruction
\end{enumerate} 
\paragraph{a set of}
\begin{enumerate}
\item required inputs
\item cooking instructions 
\item sanity checks
\end{enumerate}
\paragraph{, such that}
\begin{itemize}
\item the desired outcome is achieved using inputs and instructions
\item the sanity checks verify that the cook is still sane
\end{itemize}

\end{deff}

这使

模拟输出

现在，我想在我的投影仪幻灯片中实现类似的功能。但是，似乎paragraph无法实现 - 以下文档会产生错误（未定义的控制序列）：

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = pdflatexmk


\documentclass{beamer}





% add page numbers for malmoe
\newcommand*\oldmacro{}%
\let\oldmacro\insertshorttitle%
\renewcommand*\insertshorttitle{%
  \oldmacro\hfill%
  \insertframenumber\,/\,\inserttotalframenumber}


\usetheme{Malmoe}
\setbeamertemplate{headline}{}
\setbeamertemplate{footline}{}
\addtobeamertemplate{navigation symbols}{}{%
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \insertframenumber/\inserttotalframenumber
}

\begin{document}





\begin{frame}

A recipe is

我需要alert{}强调列表中的某些项目，所以我不想将其用作\alert标题。我还能如何在 Beamer 中重现上述布局？理想情况下，标题上方的间距也会更小，甚至更好——这是一种让我控制它的方法。

如果您想要使用已定义的命令，则可以例如使用\structure{}：

\documentclass{beamer}

\usetheme{Malmoe}
\setbeamertemplate{headline}{}
\setbeamertemplate{footline}{}
\addtobeamertemplate{navigation symbols}{}{%
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \insertframenumber/\inserttotalframenumber
}

\newtheorem{deff}{Definition} 

\begin{document}

\begin{frame}
\begin{deff}

A recipe is 

\structure{given}
\begin{enumerate}
\item a desired outcome
\item a language of instruction
\end{enumerate} 
\structure{a set of}
\begin{enumerate}[a.]
\item required inputs
\item cooking instructions 
\item sanity checks
\end{enumerate}
\structure{, such that}
\begin{itemize}
\item the desired outcome is achieved using inputs and instructions
\item the sanity checks verify that the cook is still sane
\end{itemize}

\end{deff}
\end{frame}


\end{document}

或者您可以创建一个新命令并对其进行样式设置以满足您的需要：

\documentclass{beamer}


\usetheme{Malmoe}
\setbeamertemplate{headline}{}
\setbeamertemplate{footline}{}
\addtobeamertemplate{navigation symbols}{}{%
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \insertframenumber/\inserttotalframenumber
}

\newtheorem{deff}{Definition} 

\newcommand{\mypar}[1]{\textbf{#1}}

\begin{document}

\begin{frame}
\begin{deff}

A recipe is 

\mypar{given}
\begin{enumerate}
\item a desired outcome
\item a language of instruction
\end{enumerate} 
\mypar{a set of}
\begin{enumerate}[a.]
\item required inputs
\item cooking instructions 
\item sanity checks
\end{enumerate}
\mypar{, such that}
\begin{itemize}
\item the desired outcome is achieved using inputs and instructions
\item the sanity checks verify that the cook is still sane
\end{itemize}

\end{deff}
\end{frame}


\end{document}
