This plugin provides the ability to define abbreviations that expand only if a particular prefix is matched.
The main reason for writing this plugin was to make typing text into TeX easier. Many default abbreviations for TeX are provided.
Typing
By Fourier inversion (th~Finv}),
$$
\vp(x) = \int_R2 e^{-2\pi i x \cdot \xi} \hat \vp(\xi) dxi.
$$
produces
By Fourier inversion (theorem~\ref{thmFinv}),
\begin{equation*}
\varphi(x) = \int_{\R^2} e^{-2\pi i x \cdot \xi} \hat \vp(\xi) \, d\xi.
\end{equation*}
If you also have the tex_autoclose plugin installed, then you can type \en
to close any open environment.
