When viewing/editing a folded file, it is often needed to inspect/close some fold.
To speed up these operation use the following (put in your $HOME/.vimrc):

" Toggle fold state between closed and opened.
"
" If there is no fold at current line, just moves forward.
" If it is present, reverse it's state.
fun! ToggleFold()
if foldlevel('.') == 0
normal! l
else
if foldclosed('.') < 0
. foldclose
else
. foldopen
endif
endif
" Clear status line
echo
endfun

" Map this function to Space key.
noremap <space> :call ToggleFold()<CR>

See :help folding for more information about folding.
