Hi all - I've been playing KSP for a couple weeks now and having a blast. I'm trying some more advanced stuff now, and just recently have been doing the Mun orbit scenario. I was able to successfully undock the lander, power up the engine and land on the Mun - then regain orbit and try an approach for docking, however I can't seem to switch back to the command module. No matter what I try. The key map says that [ and ] should switch between ships, but it doesn't work for me. What am I doing wrong?
