How to ad a font style to CSS Inserts? Will it show up in visual editor font pop up?

I want to add new font styles into the 'CSS inserts' so I can then use them in a page or post. Nothing I put in the 'CSS insert' shows up in the visual editor font drop down menu.

Can you explain this?

What would be the exact format, to make these two examples:

body text
Lucinda Grand
14 pix
bold, italic
color #FF8000

heading text
Times
18 pix
bold
color #FF0080

then put it in the 'CSS insets', and then have it available in the visual editor font pop up.

I just need some exact sample I can try out so that I can see how it works.

Thanks
