Switch screen in nested session

I am in love witch screen :)

The first thing I do when I connect to a machine is start a screen session so I have multiply terminal sessions that I can switch by just a simple key stroke (CTRL-a followd by ").

CTRL-a is the most important command. When CTRL-a is send to the screen session, screen will accept the next character as a command for screen itself.
