Toggling Proxy settings quickly with Pentadactyl and Firefox

If you use the excellent Pentadactyl plugin for Firefox to get vim super-powers to the browser, here is a quick and painless way to toggle between a direct connection to the internet or using the default proxy settings. Add this to your ~/.pentadactylrc command proxy -nargs=1 :set! network.proxy.type=<args> nmap up :proxy 1<CR> nmap np :proxy 0<CR>Now pressing up (Use Proxy) will enable Manual Proxy Settings while pressing np (No Proxy) will use Direct Connection.
