    alert('Undo!')
  }
});

The same key has “Z” in the US layout and “Y” in the German layout. Omit, the event code would be equal to the key Z for people of German layout when they pressed Y.

The same characters in different layouts can be to different physical keys. which leads to different codes. , this only happens with a few codes.
