i just noticed the ctrl-[ shortcut is mentioned in the post about command line history. well done.
one more thought: someone above mentioned the ubiquity of readline and emacs bindings. and the desirability of one standard set of bindings that works "everywhere". but if we are focusing on unix and the command line (cf, e.g., gui apps), i wonder if /bin/sh is not even more ubiquitous than readline. every system that runs scripts is likely have sh.
so from any shell one could type /bin/sh and then set -o vi. and then one is in familiar territory.
and according to the open standards group, if it's a terminal that supports command line editing, it should have vi mode.
i like both types of bindings, but i wonder which is really more ubiquitous.
