How do you insert paragraph marks automatically?

I already know how to find and replace paragraph marks within OL Writer, by finding “$” and replacing with . I would like to know how to insert paragraph marks by using the find and replace process to find a special mark (I usually use “#” which I have put in places that I would like a paragraph mark) and replace “#” with a paragraph mark. I have tried Find # and replace $ but all I get is an actual dollar sign and not a paragraph mark.
thanks in advance

In the “Find & Replace” dialog open the Other options part and enable Regular expressions. Then use \n in the “Replace” field.
