If a line appears in your document that you cannot select and therefore cannot delete, it may be a paragraph border. Word creates it when you type three or more hyphens, underscores, equal signs, asterisks, tildes, or hash signs and then press Enter. By default, Word converts these characters into a border at the bottom of the paragraph.

To get rid of the line in Word 2007:

1. Click the Home tab.
2. Within the Paragraph group, click the arrow beside the Border button.
3. Select No Border.
