Thanks for your time.  I tried the new entry for \overunderset in
amsmath.el, but it seems wrong to me with a minimal sample like this.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\(\overunderset{above}{i=below}{\prod}\)
\end{document}

Isn't the right entry like this?

diff --git a/style/amsmath.el b/style/amsmath.el
index 65aed4e2..2c06380b 100644

+    '("overunderset" "Symbol above" "Symbol below" "Accent symbol")

     '("tfrac" 2)
     '("binom" 2)

I think the definition in amsmath.sty supports my idea:

\newcommand{\overunderset}[3]{\binrel@{#3}%
  \binrel@@{\mathop{\kern\z@#3}\limits^{#1}_{#2}}}

(The order of the arguments is different from \overset and \underset...
I wonder why amsmath developer chose such confusing order.)
