Question 1: When I press "space bar" the screen divides into 4, it's cool but I have a small monitor and can't really use the tiny quadrants for effective work, I was wondering: is there was a similar command that would divide the workspace into 2 screens? And if so how?

Question 2: if I made a skeleton and saved it, and then rigged it to a model, and made some animations for it, could I then reload that skeleton and apply it to a different character model but transfer the animations over to it? And if so how?
