How to look up a symbol?
I want to type ^ in mathmode, but \frown is too long, so my question is where to find a small version?
Update:
Thanks to Mico. I tried \smallfrown, but it seems too big either.

Here are some options for you that scales either \frown or \smallfrown (from amssymb) down to the size of \textasciicircum:

\documentclass{article}
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
\usepackage{amssymb}% http://ctan.org/pkg/amssymb
\begin{document}
\textasciicircum $\frown$ \par
\textasciicircum \raisebox{.5em}{\smash{\scalebox{.5}{$\frown$}}} \par
\textasciicircum $\smallfrown$ \par
\textasciicircum \raisebox{.5em}{\smash{\scalebox{.5}{$\smallfrown$}}} \par
\end{document}
In the above MWE, both \frown and \smallfrown is raised to the level of \textasciicircum for comparison using \raisebox, and scaled down to 50% of its original size (via \scalebox from graphicx).
Depending on the choice, you should define a command that creates the frown you're after, like
\newcommand*{\myfrown}{\raisebox{.5em}{\smash{\scalebox{.5}{$\smallfrown$}}}}
say.
Have you tried \smallfrown (provided by the amssymb package)?
\textasciicircum{} or \^{} can be used within math mode using text mode

amssymbhas\smallfrown. I found this just using detexify. Please check first this How to look up a symbol? – percusse Jun 25 '12 at 14:26\scriptstylenot\scriptsize– David Carlisle Jun 25 '12 at 16:03
