Sorry for that, glad that you found it.

Yes, I found that in the manual, but I would prefer not to preview the
whole environment, only the relevant snippet. Eg given LaTeX code like

--8<---------------cut here---------------start------------->8---
\begin{maxima}[]
  solve(a*x^2+b*x+c=0,x);
\maximaoutput*
\m  \left[ x=-\frac{\sqrt{b^2-4 a c}+b}{2 a} , x=\frac{\sqrt{b^2-4 a c}-b}{2 a} 
\right] \\
\end{maxima}
--8<---------------cut here---------------end--------------->8---

I would prefer to preview only the part after the \m. Or maybe
everything between \maximaoutput* and \end{maxima}. Is that possible in
AUCTeX?

Best,
