Hi Hans,

Thanks for the response. This is sort of what I wanted, except the \widehat is, well, quite wide. So I hacked it around a bit to put the \widehat from a capital 'I' on top of a capital 'H'. In case it happens to be helpful, the final macro was

\def\hhat{H\kern-0.61em\widehat{\phantom{I}}\kern0.178em}

If I really cared, I wouldn't hard-code those numbers, but since they are in em I'm not really too worried.
