Next Page Section Break

Next Page – inserts a section break so the new section begins at the top of the next page
Continuous – inserts a section break on the same page. Use this where you want different formatting on a single page, such as columns in one section and margin to margin text in another
Even Page – inserts a section break and starts the section on the next even numbered page in the document
Odd Page – inserts a section break and starts the section on the next odd numbered page in the document

For example, if the footer has text right-aligned on every page and the orientation of a page is changed from portrait to landscape there is no need to go back to the landscape page and reset the right tab to move the piece of text further right.

The Alignment Tab dialog box will open allowing alignment changes to be made. It is worth noting that whilst the text is now aligned as selected, for example aligned at the right margin, the tab marker on the ruler has not actually changed.
