This feature is only included in SoftMaker Office Professional and NX Universal. It is not available in the Android or iOS version.
The Duden Korrektor has an automatic hyphenation module, among other things.
If you enable this option, TextMaker uses the hyphenation module of the Duden Korrektor for automatic hyphenation rather than its own module. This is characterized primarily by the fact that it can use the official Duden dictionary to determine the permissible separations.
Note: The Duden hyphenation only works for text in the language "German (Germany, Austria, Switzerland, etc.)".
Enabling Duden hyphenation
To enable Duden hyphenation, choose the ribbon command File | Options 
to open the dialog box, switch to the Language tab and enable the option Use Duden Korrektor for German hyphenation.
Tip: Alternatively, open the dialog box with the ribbon command Review | Spell check 
| Settings.
From now on, the hyphenation module of the Duden Korrektor will be used (see also Configuring Duden Korrektor) instead of the module integrated into TextMaker for automatic hyphenation.
Note: The operation of the hyphenation function does not change at all. Thus, it will continue to run completely automatically if you don't intervene, and it will separate words automatically. For more information, see Hyphenation.
