[orca-list] dictionary

[Marion Peterreins <marionpeter gmx net>]

Hi all

I've been using ubuntu 10.4 with Orca 2.30.2 for several weeks now.
I tried to use the standard dictionary of gnome and the following 
problem occured:
I can only use the monolingual english dictionary but  don't know how to 
add other dictionaries like English German for instance.
Where do I find the list of dictionaries and how can I choose them?

Are there perhaps other dictionaries that can be used with orca?

Thanks in advance.
Best wishes, Marion!
