Keep several paragraphs on same page

How would I insure the text of say, three paragraphs and a heading are kept on the same page?

Select and Right-click the paragraphs, click Paragraph… Go to Text Flow tab and tick “Keep together”.

I tried the above answer. I highlighted the paragraph, right-clicked and found paragraph, but there was no Text Flow tab. I am on version (writer).
