Seems hard to imagine this is what a user would expect, but who am I to argue with POSIX? :-) For myself, the behavior I want is provided by the combination of bind-tty-special-chars and unix-word-rubout: set editing-mode vi # Disabling bind-tty-special-chars allows unix-word-rubout to work: # http://lists.gnu.org/archive/html/help-bash/2016-11/msg00004.html set bind-tty-special-chars off set keymap vi-insert control-w: unix-word-rubout Thanks, Aron
