Having a literal "@" in TexMaker user commands

I am wanting to make a user command that serves as a one-click preamble.

documentclass[answers,10pt]{article}

usepackage[margin=1.in]{geometry}
input{mystyle.sty}

makeatletter
@ifclassloaded{exam}{
usepackage{color}
usepackage[english]{babel}
usepackage{amsmath,amssymb,amsthm,mathdots}
usepackage{graphicx}

definecolor{SolutionColor}{rgb}{0.1,0.3,1}

unframedsolutions
shadedsolutions
definecolor{SolutionColor}{rgb}{0.9,0.9,1}
renewcommand{solutiontitle}{textbf{Solution: }}
}{
newtheoremstyle{sol}
{3pt}
{3pt}
{}
{}
{bfseries}
{:}
{.5em}
{}
theoremstyle{sol}
newtheorem*{solution}{Solution}
}
makeatother

Above is that preamble. However, since "@" is the texmaker syntax for a wildcard, it defaults to that. I was wondering if there was a way to write a literal @ that will not be treated like a wildcard.

Thank you for any help.
