Nonprinting Characters /text/swriter/01/03100000.xhp
Nonprinting Characters Shows nonprinting characters in your text, such as paragraph marks, line breaks, tab stops, and spaces.
When you delete a paragraph mark, the paragraph that is merged takes on the formatting of the paragraph that the cursor is in. To specify which nonprinting characters are displayed, choose %PRODUCTNAME - PreferencesTools - Options - %PRODUCTNAME Writer - Formatting Aids, and then select the options that you want in the Display of area.
