在 itemize 和 enumerate 内添加文本而不缩进

Question

我有这个MWE：

\documentclass{article}


\newcommand{\toleftmargin}[1]{?????}


\begin{document}
    \toleftmargin{This text should be on the left margin and already is}
    \begin{itemize}
        \item Text

        This text should be still indented

        \toleftmargin{This text should be on the left margin}

        \item Text
        \begin{itemize}
            \item Text

            This text should be still indented

            \toleftmargin{This text should be on the left margin}

            \item Text
        \end{itemize}
        \item Text
    \end{itemize}
    \toleftmargin{This text should be on the left margin and already is}
    \begin{enumerate}
        \item Text

        This text should be still indented

        \toleftmargin{This text should be on the left margin}

        \item Text
        \begin{enumerate}
            \item Text

            This text should be still indented

            \toleftmargin{This text should be on the left margin}

            \item Text

        \end{enumerate}
        \item Text
    \end{enumerate}
\end{document}

我应该创建命令\toleftmargin，通过删除参数中给出的文本的缩进，将文本带到左边距。

我不知道该怎么做。有人知道吗？

在这种情况下，我认为代码片段就可以了。请注意，您至少需要一个\par，第二个将被忽略。

\makeatletter
\newcommand{\toleftmargin}[1]{\par\noindent\hspace{-\@totalleftmargin}\parbox[t]{\textwidth}{#1}}
\makeatother
