Question

Is it possible to use multiple commands in one environment block in LaTeX? I tried something like this, but it didn’t work…

\begin{sffamily,emph}
    I'm sans serif and italic!
\end{sffamily,emph}

Answer 1

No, but there are two ways to get around that:

1) Define your own environment:

\newenvironment{sfemph}{\begin{sffamily}\begin{emph}}{\end{sffamily}\end{emph}}

\begin{sfemph}your text here\end{sfemph}

2) Use the non-environment forms (though this doesn’t work for every command):

{\sffamily\emph your text here}
