Using Direct control

Hi all, I’m trying to use the direct control to stop my ships wandering (at times) randomly around the screen. I don’t seem to be able to get them to move where I want, clicking on the ship, then trying to direct it where to go is unsuccessful. I had a look in the manual and read this:

As you see, it contradicts itself. So what actually happens when you click on an empty space???

Thanks.

I believe that you are supposed to use right-clicks for giving movement and attack orders, and left-clicks for selection and deselection.

Yep
