Line and page breaks

Hi all
I was playing arount word menus and found something interesting. Hoe can I use Line and page breaks options in word

To Open this dialog right click on the document>Paragraph > Line and page breaks
I discovered for myself that

Don't hyphenate - doesn't hyphenate
Page breaks before - starts ech paragraph on a new page

Cant understand what Window//Orphan Control, Keep with text, Keep lines together, Suppress the number means.

Can somebody explain or give link?
