Hi,

I am listing out functions used at our company so I created a list/header.

I am using the header so all I do is choose the header and then apply it to each item in my list.

1. Fund
A. Fund xyz

Then I use the "->" arrow to make the header change from Major to minor headers.

2. Fund XYZ ->
B. Fund XYZ

Here is the problem, word automatically reformats the style when I change from major to minor header. I want the header to be the format I choose but office is choosing for me.

Thanks but no thanks. How can I stop this program from upadting the format ever single time I change the heading from major to minor?

A header is text that goes at the top of multiple pages sometimes including a date or page number. The text at the bottom serving a like purpose is called a footer.

A heading is a (usually short) line of text to help describe the following text and organize a document. There are various heading styles. I am assuming that you are talking about heading styles.

These are styles.

You can modify their format by modifying the style. You can save those modifications in a Template so you can use them in future documents without redoing the work.
