I have beaten gnu screen into submission. For ages it has refused to let me start with screen number 1 instead of 0. Binding c to screen 1 was supposed to fix this. The cause? My fingers were too fast. Turns out that I need to also bind Ctrl+c. For your convenience, copy and paste the below into your ~/.screenrc if you have a similar problem.

bind c screen 1
bind ^c screen 1
bind 0 select 10
