Trabzz this is not what I meant. Thanks for a reply anyway.
I have the BTPro client. One of the patches mentioned is this one: "Orders control with alt/ctrl/shift and setting gui - by blup (explore Advanced Settings to set them)".
However there is no explanation how does this patch work. Or at least I didn't find it. I experimented with it but alt+shift seems to not work. Only ctrl has some functionality in Orders window. I also failed to find anything concerning these orders in the Advanced Settings.
Ehm, now I searched more thoroughly while writing this post and finally found it. It's not under Interface as I thought but under Construction -> Vehicles -> Controls & Orders -> Order's Shortcuts.
Finally I discovered it
