Did you know that if you switch to docking mode and hit spacebar twice, it gives you a type of "hold" mode? When you hold the spacebar, it switches to rotation mode (or translation, not sure) and when you let go, it reverts. I didn't until the game lagged out and I hit it one too many times. The more you know.... And, if you hold shift on a ladder, then hit a directional key, your Kerbal jumps off in that direction? I mean really...
