If the reason you want to force a page break is to prevent a paragraph from splitting over a page break, a better way to do this is to go the Rows section of the Changing style dialogue box for the base style of your document, and to select the Unbreakable rows option. This will prevent any paragraph in the style from being broken over a page break.
If you just want to keep a single paragraph unbroken, apply Unbreakable rows as an effect to it.
