One fun tidbit about using Vi keybindings in readline is: you can use '*' as a wildcard when searching history. You can't do it in the default Emacs mode. I use this all the time! Originally I read about this feature in a POSIX spec, noticed it did not work, and filed a bug with readline about it. They fixed the bug, but since it was only mentioned in the spec for Vi mode, they did not add the feature to Emacs mode. I'm glad to have done my part to make Vi mode strictly superior to Emacs mode (:
