If you’ve formatted your document with columns (such as a newsletter), you know that your text will automatically flow from one column to the other. You can also insert your own column breaks if you want, which gives you more control over the formatting of your document.
Place your cursor where you want the column to break.
Click Page Layout > Breaks. A menu with options will appear; click Column.
A column break is inserted. Click Home > Show/Hide to see it.
Tip: The keyboard shortcut Ctrl+Shift+Enter also inserts a column break where you’ve placed your cursor.
You can also delete any column breaks you’ve inserted.
