Range.InsertBreak (Word)

Inserts a page, column, or section break.

When you insert a page or column break, the range is replaced by the break. If you don't want to replace the range, use the Collapse method before using the InsertBreak method. When you insert a section break, the break is inserted immediately preceding the Range.
