In OSX Lion, in vim, I try use this nnoremap.

nnoremap <m-Down> :cnext<cr>zvzz
nnoremap <m-Up> :cprevious<cr>zvzz

vimrc from sjl

I added the nnoremap to ~/.vimrc, but when I press ALT-Down nothing happening.

If you are using Vim in Terminal.app, the Alt key doesn't work by default. You must enable it in its preferences, it's a checkbox labeled "Use option as meta key" in the settings panel.

But you could use MacVim which understands the Alt key by default.

But you could use <leader><Down> and <leader><Up> which are going to work everywhere, :help mapleader.
