German Language

Following shortcuts are quite useful for Excel (only German language pack).

Some of these commands are really annoying. I am thinking of getting the English version as an extra language pack for Windows 7. Microsoft should keep shortcuts consistent accross all locales and not change it depending on the language settings.
