String indication

[David Raleigh Arnold]

I pulled this from the "Lyxtips" file.  Can you include it without too
much trouble for string indication?

=============
circle with letter in it 

\newcommand\kreis[1]{\ensuremath{\mathbin{\settowidth{\dimen7}{\mbox{$\bigcirc$}}%
              \makebox[0pt][l]{$\bigcirc$}\makebox[\dimen7]{#1}}}}

\kreis{u} prints a circle with an u in it.
