Using a german keyboard (and thus also german system/input language), the game shows that the shortcut for jumping to the town center is z but when I press z on the keyboard, nothing happens. Contrary if I press y, which is exchanged with the position of z on a german keyboard compared to an english one, the jump works.
Edit: the same also applies to other shortcuts: For example changing the game speed is set to minus and equals according to the controls menu but on the german keyboard the actual keys that work for this are ´ and ß which are also at the same place on a german keyboard.
I suppose similar issues will also occur with other keyboard layouts that deviate from the english one.
