Shortcuts on Swiss German Keyboard

Is it only an Apple Switzerland thing or also in Germany? The keyboard shortcuts are absolutely not thought through. For instance: since one of the latest update of Numbers the shortcuts for zooming in/out are CMD+; and CMD+:

This is not only completely unusual but they bite with the opening of the prefs (which is almost always CMD+;).

I wanted to change it in the Sysprefs > Keyboard > Shortcuts but it does completely weird things (one time it does zoom, then with the next keystroke it doesn't,... afaik there are no clashing commands. I chose CMD+< and CMD+SHIFT+< - these were the original ones before the last update.

Please Apple Switzerland/Germany/Whatever - test your stuff.
