If you're finding that 'zo' and 'zc' are hard to type or remember, you could use <spacebar> and <backspace> to open and close folds:

nnoremap <Space> zo
nnoremap <backspace> zc

Or, you could just use the <spacebar> to do both:

nnoremap <Space> @=((foldclosed(line('.')) < 0) ? 'zc' : 'zo')<CR>

Using za is easier - see :help za.

Better add the following mappings:

inoremap <F9> <C-O>za
nnoremap <F9> za
onoremap <F9> <C-C>za
vnoremap <F9> zf

With these mappings, one can create folds in Visual mode and open/close folds in the other modes.

Space already works out of the box for opening folds. The idea for backspace to close again is a good one and will surely make it into my .vimrc :)

zA - toggle open/close folds recursively.

Tip 108 is better than this. It won't affect normal functionality of <Space> when cursor is not on folding.
