+You can use {{{screen -x}}} to attach a screen session that's already attached somewhere without detaching it first. This can
+have side effects if the other place is already attached or is in a window that is a different size than your current one.
+It's useful when you want to share context between different screens, or even different people, but doing it when you're not
+sure where else your screen might be attached has privacy implications.
+
+== For More Information ==
+
+{{{screen}}} can do lots of stuff. If you have a while to burn, run {{{man screen}}} at the shell prompt. It may be helpful to do this inside of screen
+so you can put it down and come back to it later.
+
+=== TODO ===
+
+clean up, explain the "C-a C-a" notation.
