title: GNU Screen: Changing Global Key-binding
body: <p>I've recently started using screen in remote sessions.  One problem is that emacs doesn't recognize its C-a and I don't want to bind emacs C-a to something else, as I'm very used to it.</p>
  
  <p>Google shows ways to change every keybinding individually using ~/.screenrc  but not how to change a keybinding globally.  I want all C-a to change to something else.  Is that possible?  What are my options?</p>
  
  <p>Thanks for your answers</p>
