To escape many _ in LaTeX efficiently

问题:

How can you escape _ without the use of \_?

This is the example of the question

word_a_a_a_a_a_b_c_dd

There is one function which you can use for this. However, I cannot remember its name.

回答1:

Are you thinking of the underscore package, which redefines the underscore symbol so that you don't have to escape it in text mode? See here.

回答2:

Other than verbatim I wouldn't know.

Verbatim environment:

\begin{verbatim}
  word_a_a_a_a_a_b_c_dd
\end{verbatim}

Inline:

\verb|word_a_a_a_a_a_b_c_dd|

回答3:

I couldn't get the underscore package to work, so I used the url package:

\usepackage{url}
\urlstyle{sf}  % or rm, depending on your font

...

Foo \url{word_a_a_a_a_a_b_c_dd} bar.

回答4:

Typically you want a monospaced font in such situations, so you can use this:

\verb|word_a_a_a_a_a_b_c_dd|

回答5:

You may also be thinking of the lstlisting or verbatim environments, which are commonly used to display code - which can contain underscores. However, these environments do a lot more than just "escape" underscores.
