Change of notation

[the_riviera_kid]

Regex to the rescue. I don't use regular expressions too often, so I'm leaving this entry for myself as an example for future reference.

To change every instance of \calU^{*} to \calU^{(*)},

find: \\calU\^\{\(0*\)\}
replace: \\calU\^\{(\0)\}

It'd be hard pressed for that to have been much easier.
