I switched to Vi-mode long ago.  You can type "set -o vi" directly on 
command line or from login scripts.  Actually, Bash's command line 
processing is handled by "readline" library, which reads ~/.inputrc. 
So, you can use that for anything using "readline".

Even though I'm a Vi guy, there are 2 Emacs-style line editing that I 
use a lot: (in ~/.inputrc)
	C-f: unix-filename-rubout
	C-e: yank-last-arg
where
	"unix-filename-rubout" -- deletes back to the last '/' char.
	"yank-last-arg" -- pastes the last arg from previous lines.
"C-f" and "C-e" are my key assignments.  You can assign to any keys.
