Unfolding vim-latex fold

I don’t know about you guys but I found it is very annoying to have my sections and subsections to be folded in vim/gvim , since somehow I mistakenly put “i” since I want to change to insert mode to unfold (although it should be :za) .

So now, the cruelest method is by

:set foldlevel = 5

usually I put 10 heh.

(since section,subsection and subsubsection may =3 .. so play safe with above that level).

But so far I did not managed to get it work by putting in in $HOME/.vimrc . Any hints?
