Change the keys for changing windows gone in Mavericks

When I got my Mac-Mini, I've changed the cycle-through windows key from ⌘` to ⌘0 (since on the Hungarian keyboard layout I should press ⌘⌥ű, and never could remember which one is it from 5 other key.)

In Mountain Lion this option was still present, but now it is missing from Mavericks. I can't find it in the Keyboard & Input section anywhere. The entry for ⌘⇥ is also missing. This became problematic only now, because I only noticed now, that it clashes with a key combination in Microsoft Outlook. (I don't know if this problem come with the update, or had it before.)

Can anybody help how can I change this option or how to restore it? I would like to set it to ⌥⌘⇥ and ⇧⌥⌘⇥ as I did it once before. (Or ⌃⌘⇥ should be more comfortable.)

Solution 1:

On my installation of 10.9 the shortcut can still be changed from System Preferences > Keyboard > Shortcuts > Keyboard > Move focus to next window:

I don't think it was ever possible to change command-tab to another shortcut though.
