            Switch to German (Germany) keyboard layout and type
            few characters using <AltGr> key.
            Note: on windows keyboards without an AltGr key,
            you should use Ctrl-Alt to synthesize AltGr.
            For example, on German keyboards, `@' is AltGr-Q
            `{' is AltGr-7 and '[' is AltGr-8
