Richard, could you tell me if I have interpreted your above expression
correctly.

I believe this is saying
~ matches
^. starts with seven preceding characters
\d represents a digit
So it is saying look past seven characters "^.{7}" and check that next
character if it is an interger "\d"
Is that a correct narrative for what is going on?
