At the bottom you have these options to apply in different ways.
- Click Whole document if you'd like the same margins used throughout the document.
- Click This point forward if you'd like the new margins to apply to the pages of the document beyond the cursor's current location.
- Click Selected sections after selecting a block of text in the document in order to apply the new margins only to the text you selected.
