(1) When I open my Trados TMs, I never see the text contained in them. Is there a way of making it visible OTHER THAN by exporting the TM into an external file (.txt, .tmx)?
That's the only way, I know of.
(2) Is there a way I can edit Trados TMs directly (that is, WITHOUT exporting the TM into an external file, editing that external file and reimporting it into the TM)?
You can use Maintainance in the Files menu for this. It is VERY useful - for instance to global-search-and-replace wrong terms, and/or do more advanced concordance searches.
