FONT SIZES button?

[PeterB]

As well as the FORMAT button (h1, h2 etc.)
I'd really love a 
FONT-SIZE
extralarge, large, small, etc.

Is that already built in? and named what for the BTNS[] array?

If it's not built in, is there an EASY example of how to add it?
I'm not understanding the create drop downs so far :-(

Any ideas?

Many thanks
Peter
