I dislike how the default escape key in screen is Ctrl-a. When I am using the command line I am constantly moving back and forth within the line being edited. Hitting Ctrl-a a requires me to stop and think, and by that time I have typed ten keys and caused screen to do something I did not want. Transposing characters on the other hand is something that I hardly ever do. Transposing always requires me to stop and think. Does the cursor go on the first or last character? I always forget, so I map the screen action key to Ctrl-t t. This is how.
# .screenrc escape ^Tt startup_message off defscrollback 50000 hardstatus on hardstatus string "[screen %n]: %?%h%:%t%?" defhstatus ""
