I use backquote (i.e., I have "escape ``" in my screenrc). For some reason this appeals to me more than a control sequence, which I blame on Emacs. For a long time I used Emacs under screen almost exclusively, and I was desperate for a screen command sequence that didn't conflict with Emacs---which ruled out almost all the control key combos. Reaching for the top corner of the keyboard to begin an escape sequence feels pretty natural to me because of my history with Emacs on terminals that don't support the Meta modifier, and backquote doesn't conflict with key bindings for the editing modes I typically use in Emacs. Backquote is used infrequently enough in other contexts for it to interrupt my typing, with the exception command interpolation. (I wish I could say I came up with it on my own, but it was actually a friend of mine who clued me in.)
