I would like to insert some explanatory text between two items of a numbered list.

Is there a command that can do this in the same way as the \intertext command in an align environment?

  • Do you think it looks nicer to indent the intertext the same amount than other items or remove the indentation? – skan Nov 6 '17 at 12:18

Use the enumitem package and two separate enumerate environments, adding resume as option to the second environment.

\documentclass{article}

\usepackage{enumitem}

\begin{document}

Some text.

\begin{enumerate}
\item First item of enumerated list.
\item Second item.
\end{enumerate}

Some explanatory text.

\begin{enumerate}[resume]
\item Third item.
\end{enumerate}

\end{document}

  • Exactly as explained in [the enumitem package documentation](www.tex-tipografia.com/archive/enumitem.pdf) on page 6. – yo' Sep 30 '13 at 8:48
  • It works! And it looks like I used to wrong key words for my search. – Jan Sep 30 '13 at 8:50

    May be you can define a command: \newcommand{\myintertext}[1]{\end{enumerate} #1\begin{enumerate}[resume]}. – user11232 Sep 30 '13 at 8:58

    If one uses \usepackage[shortlabels]{enumitem}with more sophisticated labels the possibility to use multiple arguments is very helpful: \begin{enumerate}[step 1):, resume] – Jakob Aug 10 at 13:34

Here is a custom command, \enumeratext, which works like \intertext, it does not require enumitem:

\newcounter{saveenumerate}
\makeatletter
\newcommand{\enumeratext}[1]{%
\setcounter{saveenumerate}{\value{enum\romannumeral\the\@enumdepth}}
\end{enumerate}
#1
\begin{enumerate}
\setcounter{enum\romannumeral\the\@enumdepth}{\value{saveenumerate}}%
}
\makeatother

Example:

\documentclass{article}

\newcounter{saveenumerate}
\makeatletter
\newcommand{\enumeratext}[1]{%
\setcounter{saveenumerate}{\value{enum\romannumeral\the\@enumdepth}}
\end{enumerate}
#1
\begin{enumerate}
\setcounter{enum\romannumeral\the\@enumdepth}{\value{saveenumerate}}%
}
\makeatother

\begin{document}
Here is a list:
\begin{enumerate}
\item Something,
\item some other thing,
\item and more;
\enumeratext{Some intertext}
\item let's continue,
    \begin{enumerate}
        \item here is a sublist,
        \item some stuff,
        \enumeratext{more intertext}
        \item yet another stuff.
    \end{enumerate}
\item last thing.
\end{enumerate}

\end{document}

Update: Now works for lower level list.

Here is an analogue for \intertext called \listintertext:

enter image description here

\documentclass{article}

\makeatletter
\newcommand{\listintertext}{\@ifstar\listintertext@\listintertext@@}
\newcommand{\listintertext@}[1]{% \listintertext*{#1}
  \hspace*{-\@totalleftmargin}#1}
\newcommand{\listintertext@@}[1]{% \listintertext{#1}
  \hspace{-\leftmargin}#1}
\makeatother

\begin{document}

\noindent
Some text.

\begin{enumerate}
  \item First item of enumerated list.

  \begin{itemize}
    \item First bullet.

    \listintertext*{Some explanatory text.}

    \item Second bullet.

    \listintertext{Some explanatory text.}

    \item Third bullet.
  \end{itemize}

  \item Second item.

  \listintertext{Some explanatory text.}

  \item Third item.
\end{enumerate}

\end{document}

The starred version \listintertext* always sets the text flush with the left margin, regardless of the nesting depth, while the unstarred version \listintertext sets the text with only the current list depth left margin removed.

  • when the explanatory text is longer than one line, the remaining lines are indented, As far as I can tell this command just applies negative space "its contents", but I cannot come up with a way to extend that to multiple lines The reason I'm focusing on this answer is that I'm trying to use it in a custom list – Mahoma May 15 at 5:58

    @Mahoma: I'm sure one could place the content in a \parbox with some \struts. That would allow multiple lines. – Werner May 16 at 3:36

I achieved the task by just putting \item[] instead of \item in front of the inter text

  • Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – Seamus Jun 9 '16 at 10:48
  • This is the easiest solution. Though some may prefer a non indented one, and it's not as easy as using \noindent – skan Nov 6 '17 at 12:12

This is not necessarily better but I have used the following, due to Michel Bovani, for many years:

            \makeatletter
            \newcommand{\interitemtext}[1]{%
            \begin{list}{}
            {\itemindent=0mm\labelsep=0mm
            \labelwidth=0mm\leftmargin=0mm
            \addtolength{\leftmargin}{-\@totalleftmargin}}
            \item #1
            \end{list}}
                \makeatother

The only improvement I have ever wished is to be able to control the vertical space above and below the interitemtext.
