How to achieve the following in memoir class:

Question

Consider the example attached below, taken from the memoir package documentation.

I would like to be able to replicate how the words "lines" and "nearest" appear in the margins. For example, say I am defining Coulomb's Law, I would like "Coulomb's Law" to appear in the margin in a similar fashion when I write about it in the main body text.

EDIT: I would like to achieve this without the use of a list environment, which for example @Vinccool96 has provided.

EDIT 2: I would like the command to apply to a specific word in a body of text, and produce result as shown in the screenshot, while also retaining the word in the body of text without necessarily altering its in text appearance, just adding the word again in the margin with the \texttt{} font.

Answer 1

It seems you simple want to write an important word into the margin of your document.

Please see the following MWE (important code marked with <=====)

\documentclass{article} 

\usepackage{blindtext} % <========================= to create dummy text
\usepackage{showframe} % <========= to visualize typing area and margins
\newcommand{\myimportant}[1]{%
  \marginpar{\texttt{#1}}#1% <========= text in margin same text in text
}


\begin{document} 
\blindtext
blafasel \myimportant{word} % <=========================================
blub \blindtext 

\end{document}

and its result:

Be careful: too many \myimportant commands near to each other can result in ugly output ...

Answer 2

I uses the itemize environment with custom labels, the text is made with the \texttt{} command:

\documentclass{article}

\begin{document}

    \begin{itemize}
        \item[\texttt{lines}] This is similar to \texttt{classic}, but results in a 
        smaller final value.
        \item[\texttt{nearest}] The calculated value is the nearest to the given value
        while still maintaining the relationship
    \end{itemize}

\end{document}

Answer 3

In memoir you can use the \marginpar macro; see chapter 12 in the documentation (> texdoc memoir). For example:

\documentclass{memoir}
\newcommand*{\mymarginpar}[1]{\marginpar{#1}#1}
\begin{document}
This is similar to lines\marginpar{lines} but produces a smaller value.

The calculated value is \mymarginpar{nearest} to the given value while
still maintaining a relationship.
\end{document}

Depending on how you want everything to look you might want to add additional information (like fonts to use) in the \marginpar macro. read the manual for additional information.
