using the new FCKConfig.CoreStyles

In my system I do not want the user to be able to see all the options that are displayed by default in the "Format" menu on the toolbar.

In 2.4 I used:
FCKConfig.FontFormats = 'h1;h2;h3' ;

And all that showed up was those 3 options.

How do I customize what is displayed in that menu under the new CoreStyles system??

Also In this particular implementation I have FCKeditor set to use br instead of p tags.

I want to be able to select "Normal" from the format menu to remove a H1 or H2 tag on the selected text, but I dont want it to get wraped in a p or div tag. I just what the h1 or h2 tag to be removed.

So if this was my starting text

<h1>Some title</h1>
Autem qui te lobortis duis dolore, eu minim tincidunt. Facilisi duis, ipsum eum ullamcorper hendrerit aliquam dolor feugiat.

I would want it to look like this after selecting "Some title" and selecting "normal" from the format menu

Some title 
Autem qui te lobortis duis dolore, eu minim tincidunt. Facilisi duis, ipsum eum ullamcorper hendrerit aliquam dolor feugiat.

Or ideally

Some title<br />
Autem qui te lobortis duis dolore, eu minim tincidunt. Facilisi duis, ipsum eum ullamcorper hendrerit aliquam dolor feugiat.

Thanks.
