That, Brian, is an understatement !!!! :-)
And Jonathan, thanks, but I just dabble with stuff.

In fact the "*" is greedier than the "+". How about the "+" instead
of the "*" ?

This expression would probably do similar stuff
Search : ^([^\.]+)\.
Replace : «$1»
However, if one ran a SECOND or subsequent replace, the match occurs
even for the first (or prior) replacements. Probably this would help
to prevent it:
Search : ^([^\.(«|»)]+)\.
Replace : «$1»
I apologize for having taken the contents of this thread beyond the
