able to translate to and from all the languages listed in the “Choose Language” button?
The languages listed represent all the possible Translation Memory (TM) directions supported by Document. If you have enough data in your Translation Memory eXchange files (TMXs) to accomplish translation of your document, then you can use the Workbench interface. However, the Machine Translator (MT) included in the application only supports translation to or from English and whatever secondary language(s) you have purchased. For a discussion of Machine Translator (MT) vs. Translation Memory (TM) please see a previous question or the Welcome chapter of the Document User Guide.
