-====== Single Optional Argument for a LaTeX Macro ====== 
  
-I recently needed to create a new macro for a User manual. The macro was to output a defined character, but in a colour specified by the author. Therefore, I needed a macro that accepted a single optional argument. 
- 
-After doing a lot of searching around, I could only find advice on two or more arguments. I needed this: 
- 
-<code latex> 
-Print my symbol in black \specialsymbol please. 
-Print my symbol in red   ​\specialsymbol[red] please. 
-Print my symbol in blue  \specialsymbol[blue] please. 
-</​code>​ 
- 
-The macro is: 
- 
-<code latex> 
-\newcommand{\specialsymbol}[1][black]{% 
-\begin{myfont}% 
-\textcolor{#​1}{`}% backtick character contains the symbol in the "​myfont"​ font. 
-\end{myfont}% 
-}% 
-</​code>​ 
- 
-And for extra niceness, if you want your macro to ensure text following the symbol does not butt up hard against it, change line three to: 
- 
-<code latex> 
-\textcolor{#​1}{`}\ % 
-</​code>​
