--- Comment #2 from Yolande Haneder yolande@haneder.biz 2007-08-29 23:36:53 --- Workbench is a part of Trados.
Workbench is the tool to analyze documents for translation, create and manage the translation memories or set the settings for term recognition.
It is working either for .doc documents as a separate add-in to word (using macros) or together with a second utility called Tag Editor, which is an interface for processing documents of a wide range or formats (including .doc format).
You can only have it when you use Trados, on its own it's worthless.
