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.

isn't this what 'za' does? would it be better to just map space to za?

| The problem with just maping space to za is that it wont function as space if it isnt on the folded line.

This command breaks the behavior of <Space> outside folds: it moves the
cursor 3 columns instead of 1, at least for me. Fix: I use
normal! "
instead of
normal! l

| Check and make sure you didn't paste in any extra spaces at the end of the "normal" line. It was moving too far for me, too, but now moves one space since I deleted the space after the "l" which I had pasted in there.

This line:
noremap <space> :call ToggleFold()<CR>
Should be changed to:
nnoremap <space> :call ToggleFold()<CR>
Without doing that, you cannot use the <space> to represent characters, for example:
4c<space>
Would mean change the next 4 characters.

There is more shorter way to do the same:
nnoremap <silent> <space> :exe 'silent! normal! za'.(foldlevel('.')?'':'l')<cr>
Explanation:
- 'normal! za' toggles folds.
- 'silent!' allows to avoid error message when current line doesn't
delong to fold.
- (foldlevel('.')?'':'l') adds forward moving only if current line
doesn't delong to fold.
