Playing the German language Enderal, I had quite a problem leaving the meditation state. Trying all the keys, I discovered "Z" did what "Y" was supposed to do. This morning with my brain refreshed, I recalled that the German keyboard is different from the English keyboard; especially the Y and Z locations are reversed. There are several other differences, especially in the location of symbols. So if you are trying to play the German version with an English (US/UK) keyboard and encounter difficulties, I suggest you search the internet for an example of a German keyboard to help identify the problem.
[I recall in my foggy memory this issue had occurred years ago with some other RPG that was originally in German (Two Worlds or Gothic, I think), where a problem existed because the _- key and the ?/ key locations were reversed.]
I wonder if this might be a problem when the English version is released. Perhaps there will be a warning in a "read me" file.
