keyboard shortcut on german keyboard

Dear Paul or anybody,
I have a german keyboard. I can zoom out easily with the minus key, “-” , but I haven’t found the shortcut to zoom in. The “=” on the german keyboard is the shift of the number 0. Can I possibly set this shortcut myself?

Window > Key Bindings

Expand the “Editor” category, scroll down to find “Zoom In” and “Zoom out”.

Thanks so much!
