Thanks. Another person suggest the use of \skew to me, off-list for
some reason. I did indeed fiddle, and found that
\skew{3.2}\ddot{\widehat{Q}}
gave me results that "pleased" me. It was not clear to me initially that
one could give \skew fractional arguments, like 3.2, but it seems that
one can if one wraps the argument in braces {...}.
Thanks again.
cheers,
