See Changing the Default Font in Microsoft Word. (The links provided by JimP are very good things for you to read if you want Word to work with you instead of seeming to work against you. Reading them should more than save you the time it takes to read them if you regularly use Word for more than single-page documents.)

Suzanne Barnhill put it succinctly in another forum:
"The font for many styles in Word (unless you change it to a specific font) is defined as being either the Body font or the Heading font. This is determined by the theme. If, instead of assigning a specific font to a style, you choose Body or Heading, then if you apply a different theme that uses different Body and Heading fonts, your styles will change automatically. You still define the font size and other properties (Bold, Italic) in the paragraph style, but the font itself can be variable. If you want only specific fonts for the styles (and this would especially be true in a template that used more than two fonts), then you can define them in the template styles; they would then not change if you applied a different
theme (though some other elements, such as colors, might).



"You can see how this works (with Live Preview) by selecting a document that has both headings and body text in it and then hovering over the various theme font sets" ...

Heya Jim and Charles
Thanks very much for the links and quotes. Unfortunately I can't read it all in one sitting so am just responding after going through some of the links and the links in the links.

I am still not 100% sure what the +Body and +Heading refer to however I don't think I really need to worry about them. In Suzanne's quote she seems to refer to them as part of a theme and I don't need a theme. I am a one man company just writing letters and guides and need to make a template for my letters and one for my guides to match my company logo.

I am using the built in Styles and will adjust the Font, Colour, Size and Paragraph setting as needed.

As a side note, where my confusion with +Body and +Heading started was I was trying to understand what I was reading in the 'Preview of Normal:' section.

Font: (Default) +Body (Calibri), Left

I read this as 'the Normal Style is defines as'
Font = (The Default Font) + Something Called Body (Which is currently Calibri)

So the Normal style font is made up of 2 parts - The default font and Calibri?

Delving deeper, when modifying the Normal Style, using the Formats Drop Down List and selecting Fonts, I can see +Body and +Headings are listed as a Fonts? To Microsoft - If its not what the average user knows as a font please don't include it in a list of fonts.

I still haven't found where these mysterious entities are defined.

To be honest I have been working with computers since the 1980's,in DOS I wrote letters in WordStar. Over 3 decades later and I still can't get my head fully around word processing and its jargon :-)

Thanks again for your time
Steve
