Solved What craft I will be controlling when two crafts are undocked?

[GreenLittleManOnMars]

Hello!
I have a little problem. If there are two crafts docked in space, when I undock the crafts, which craft I will be controlling? (Suppose that both have a crew capsule each) Is it randomly selected or what is given the priority?

Spoiler: Little Note

Sorry for my high-quality English, I am still learning the languages of Earth. And also, for the stupid question.

There is a priority to how it all works. And it doesn't even matter if there is a control part fitted either.

If you undock, control will go to the least thing you controlled when those objects docked in the first place.

Thanks a lot!
