How do I apply Styles from my notebook's Style Sheet, in particular Hyphenation->False?

Question

In my notebook's private style sheet, I set the style for Text to

Cell[StyleData["Text"],  Hyphenation->False,  ParagraphIndent->0, 
TabSpacings->{2.9},  FontSize->12]

because I encounter too many mal-hyphenated words in German text (btw: is there a spelling check including hyphenation for non-English text?).

I applied Shift-Ctrl-E again to the Text-prototype cell but text cells in the notebook which I had written before did not inherit this property from the changed style sheet, as I fond out when I checked one cell with automatic but wrong hyphenation.

Even a new Text cell which I create after changing of Text Cell's properties in the notebook's style sheet appear as type Cell["", "Text"], i.e. they inherit nothing from my modified prototype.

What's wrong here?

How do I let all styles definitions from the notebook's style sheet apply to all cells with matching type in the notebook?

Answer 1

In order to switch off Hyphenation e.g. for all Text cells, execute the command

SetOptions[#, Hyphenation -> False] & /@ 
  Cells[EvaluationNotebook[], CellStyle -> "Text"];

in the notebook. Bingo!

(WRI told me that Hyphenation is a Cell option rather than a Notebook option and together with that answer they gave me this workaround.)
