What was the key used in previous version of businesses?
Do /shift? Go to the business and press N?
My suggestion is to change the key to open the Business panel to 'Z' and the reason why is, while being a Train Driver or Farmer and you open the window by pressing N, it will unwillingly change your seedtype/cargo type. I tried reporting this as a bug, which I think it clearly is because this is not something you want happening when opening a window, but it got rejected saying its not a bug. (which I believe is total bs)https://cit.gg/index.php?topic=394121.0
