What's the shortcut to switch between app documents in a Spanish keyboard? I know the shortcut to switch between app documents (or Finder windows) is Cmd+~, but in the Spanish keyboard to get a tilde you can't use a single key, you need to press Alt+Ñ.

I've tried pressing Cmd+Alt+Ñ but it doesn't work.

So how do I execute this shortcut with a Spanish keyboard layout?
You can find a complete list of keyboard shortcuts in System Preferences, under Keyboard, then Shortcuts. If one isn't listed you can also bind it to whatever you like.
