How do I make a selected bit of text non-printing?
By selecting the part you want to print in your text and then File > Print > Selection.
or
Creating Non-printing Text
To create text that is not to be printed do the following:
- Choose Insert - Frame and click OK.
- Enter text in the frame and if you want, resize the frame.
- Choose Format - Frame/Object, and then click the Options tab.
- In the Properties area, clear the Print check box.
- Click OK.
“non printing characters” refers to such as paragraph marks, line breaks, tab stops, and spaces.
To access this command:
Choose View - Nonprinting Characters or Ctrl+F10
On Standard bar, click Nonprinting Characters
Note:
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 Tools - Options - LibreOffice Writer - Formatting Aids, and then select the options that you want in the Display of area.
I recommend to have a look at the free guides, which you can download from http://www.libreoffice.org/get-help/documentation/
