The quick way to create a new document is to:
1. Start a new document from your template
2. Turn on the formatting marks in your document (so you can see the paragraph marks at the end of each paragraph)
3. Scroll to the end of your document and add a few paragraph marks at the end of the document
4. Copy the entire document, except the last couple of paragraph marks
5. Paste into your new document.
