[Tex/LaTex] Wrong direction of quotation marks

punctuation

How to change the direction of quote mark in latex?
Both of them are in same direction. How to have one in opposite direction?

enter image description here

\documentclass[12pt,a4paper,oneside,onecolumn]{iiscthes}
\usepackage{graphicx}
\usepackage{chapterbib}
\pagestyle{bfheadings}
\title{Introduction}
\date{} 
\begin{document}
\chapter{Introduction}
\section{One}
\subsection{One-One}
\textbf{''More--than--Moore"}
\end{document}

Best Answer

Use the ` key twice, instead of double quotes, i.e.

``More--than--Moore''

It is on the same key as ~ on American keyboards.
