   Text can be \emph{emphasized}.
   
   Besides being \textit{italic} words could be \textbf{bold},
   \textsl{slanted} or typeset in \textsc{Small Caps}.
   
   Such commands can be \textit{\textbf{nested}}.
   
   \emph{See how \emph{emphasizing} looks when nested.}
   \end{document}

Text-formatting commands usually look like \text**{argument}, where ** stands for a two letter abbreviation like bf for bold face, it for italic, and sl for...
