I am a ghostwriter and do several books a month. I am a rookie so I need all the Word help I can get. I am not understanding much of the incoming responses.
If others can see this, perhaps they may offer more badly needed assistance.

Heading vs headers; I'll look into that. Start my body text how? I still don't understand. Can someone please just give me the steps such as Home, document, etc

1. I sent you links because I think you need what is in the link, not to show off my ability to copy and paste.
2. You apply Normal or Body Text styles the same way you do any other style. You told me how you applied "Header 2." Normal should be right there as well. Read the links on styles. Do it now. It gives you the help you are asking for.
3. You are trying to save time. You will save time, I promise, by reading the pages that I linked.Word is a tool of your trade. If you are working with Word that much, you need what is in those pages, now!
4. This is a user-to-user support forum. Others are welcome to chime in. My attitude is that you can lead a horse to water...
