The text editing shortcuts are straight from readline http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html emacs bindings, which bash and many other programs use. readline supports both vi and emacs bindings. I am a dyed in the wool vim enthusiast, but when it comes to command line bindings, emacs' bindings are more convenient.
