An AUCTeX question

[nuki]

Hello!
I use Emacs for writing LaTeX files and I've got a question about
folding.
Folding with AUCTeX is documented here:
http://www.gnu.org/software/auctex/manual/auctex/Folding.html#Folding

Now the question: Is it possible to autofold all instances of a
certain
environment? So if I open a TeX file, emacs automatically folds all
environments of one type, for example every "\begin{align}..."? If
this is possible - how? :)
I'm really unexpierienced in writing .emacs-files or LISP.

Regards and thanks in advance,
Tim
