Suppose that I have a MME:
\documentclass{article}
\begin{document}
This is test
\begin{equation}
\int_a^b f'(x)dx=f(b)-f(a)
\end{equation}
\end{document}
we know that we can copy the text content This is test directly, while on the other hand, "copy the equation" turns out has bad format. I am wondering is there any package (e.g. navigator) or method that can copy the source code of the equation instead the equation itself?
