让我提出实施描述的行为的以下映射。
nnoremap <silent> <leader>zj :call NextClosedFold('j')<cr>
nnoremap <silent> <leader>zk :call NextClosedFold('k')<cr>
function! NextClosedFold(dir)
let cmd = 'norm!z' . a:dir
let view = winsaveview()
let [l0,l,open] = [0,view.lnum,1]
while l != l0 && open
exe cmd
let [l0,l] = [l,line('.')]
let open = foldclosed(l) < 0
endwhile
if open
call winrestview(view)
endif
endfunction
