So the question remains wether these macros are a good
candidate for
investing time in making them "better".

Yes, that's what happens, but I'm not very fond of it.
Sorry, I was not
clear enough when I described how I think S&R can be
automated.

I think that recording specific S&R actions in general
is useless. The
only S&R actions that are applicable in a general way
are "Replace all",
"Start searching and ask me wether the found text
should be replaced
until no more occurences are found or I stop it" and
"Search and replace
the next occurence of this text". So recording a
single "Replace" is
useful, but having a *combined* macro that contains several
"ExecuteSearch" steps where some of them
replaced the text and some
didn't is useless: you can't apply it to any other text
than the one you
recorded it for (except some very rare cases).

Yes, I understood, sorry for not answering to this directly:
I don't
know how to accomplish that. Perhaps Oliver Specht has an
idea, I will
ask him.

Best regards,
Mathias
