Add my styles to dropdown without HTMLEditor?

I've seen other threads on this, but they all refer to HTMLEditor, which I don't have. Is there a way to tweak a setting within individual files that will allow my styles (h1, h2, etc.) to appear in the editor dropdown? Right now all I'm getting is "Red Title"...and I'm fairly certain I'm not going to want my clients to use that one in my lovely designs.

Thanks so much!

You can always edit the CSS file to create your own styles

Thanks, but I'm not sure which css file that would be. I have the one I built for the site, but I'm not sure how to get those styles to appear in the editor's dropdown.

You can put in custom styles into the editor by going to the HTMLEditor folder and opening the fckconfig.js file. You can add styles here:
FCKConfig.CustomStyles =
{
'Red Title' : { Element : 'h3', Styles : { 'color' : 'Red' } }
};
