I have been using GNU Screen for a couple of years. It comes in very handy when accessing multiple terminal windows. Yesterday, I found this tip page in the Gentoo wiki. I was actually trying to figure out how to do something else when I stumbled onto changing the escape sequence section.

As part of the bash shell, I frequently use the ctrl-e (end of line), ctrl-r (reverse history search) and ctrl-a (beginning of line). I had looked for something like this before, but just didn't find it. Since changing the escape sequence, I have the ctrl-a binding available again in the screen terminal shell. I wonder how long it will take me to learn that the back-tick is my new escape sequence (it does seem more convenient when I remember).
