For example, you can use a different section to rotate a page to landscape or portrait mode, add a different header or footer, or format the section into columns without affecting the rest of the document. This is a better option than pressing Enter a few times to move the text to the next column, since doing that could mess up your formatting if the font size changes or you edit the text.
Column Break: If your document is formatted into multiple columns, you can force text from the first column to move to the next one.
