I've been playing KSP for a couple months now and have progressed to docking multiple ships together to create space stations. I watched several different tutorials on youtube to learn how to reliably dock. However, I've noticed that no one uses the docking mode. I have tried using it, but I'm confused as to what it's supposed to do other than alternate between translational and radial directional keys. Nothing shows up on the little window when I click the docking mode button. I see the crosshairs that shift around as I adjust my trajectory, but what am I supposed to line it up with? If someone has a link to a video that explains the ingame docking mode, I'd appreciate seeing it.
