Dear Nick,

thanks for helping.

What do you mean by "better solution"? As far as I can tell, your approach is
precisely what Suvayu pointed to. Using your approach, of course much more is
possible, please look at the create "enumitem" package with all its
customizations.

But this approach is a no-go for me (at least at the moment) mainly due to the
following reasons (please let me know if I'm wrong, I'm a total newbie to
org-mode):
1) I have about 40 lists in one file. Having to put in special LaTeX commands
is not an option (maybe on only has to type it in once, but then it can easily
get overseen, e.g., when you move lists around and the one containing the LaTeX
commands is not the first one in the document anymore)
2) org-mode is basically a "better" text-mode. I don't want to have LaTeX code
in there if I print it as a .txt file.

Is there a solution without having to put
before each list? Can this be set anywhere in the preferences?

But I assume that I still have to put in lists in org-mode like this: 1.,2.,...
or 1),2),... and can't put them in like this (1),(2),...?
Hmm... this is indeed a drawback. The latter lists a far better visible, they
are more consistent with respect to other list types such as (i), (ii), etc.,
and ultimately also with respect to numbering of equations. There are probably
even more typographic reasons to display lists like this. For example, if you
refer to a list within a theorem environment (which has a label itself) and you
use 1., 2.,... lists, then this looks like this:
Theorem 1.2 2. shows that ...
The eye hardly sees that one means Theorem 1.2 Part (2). Even worse, when
reading this, one thinks that the sentence stops after "2.". It's really a bad
thing, and not getting much better with right-sided parentheses.

Cheers,

Marius
