I have downloaded and successfully installed the Vim-LaTeX Suite from http://vim-latex.sf.net.
It is a great tool, but slightly annoying that when you open a file it folds all of the text and puts the folds in a collapsed state, as this page of the manual states:
http://vim-latex.sf.net/documentation/latex-suite/latex-folding.html
So you have to type zR
to expand everything each time you open a LaTeX file.
Typing zR
is obviously not hugely annoying, but I was wondering if there was an easy way to disable this functionality, so that the file is displayed with the folds uncollapsed by default?
