modify syntax highlighting in auctex

[Fabian Braennstroem <fab@ddorf.de>]

Hi,

all I want to modify syntax highlighting in auctex for the
use of beamer documents. Each frame/slide starts with the keyword
'frametitle' and now I want that is has the same style like the
'subsection' keyword, but with a different color, e.g.
green.
I found in 'font-latex.el' the part where 'subsection' is
defined and tried to add:

   ("title-3" ("frametitle")
   font-latex-title-3-face 2 (command 1 t))

to change the style to my own config, but it doesn't work.
There is probably another part where subsection is somehow
defined.

The whole frame-environment looks like:

\frame
{
\frametitle{ something }
  some text
}

Maybe, it is even possible to change the color of the words
frame and framtitle and enlarge and color the title-text!?

Greetings, Fabian
