Latex: Opening and Closing quotation marks

Opening quotes are ``and closing quotes are ":

\documentclass{article}

\begin{document}

``Thanks!"

\end{document}

>>>>>> the following proposed solution did not work for me! (NEO)<<<<<<<<<<<<<<<<<<<

For greater control over your quotations (in particular, for your concrete "search and replace" problem), you could consider using the csquotes package:

\documentclass{article}
\usepackage[english]{babel}
\usepackage[autostyle]{csquotes}

\begin{document}

\enquote{Thanks!}

\end{document}
