OK, but how to you choose how a key must behave? You need one single
object that knows the configuration of keys (is pageup history, or
nothing?), and what if I want to switch to VI mode, you don't want to
implement this in all the frontends.

Sending a string defeats the goal of readline: readline is what
translates keystrokes to a command string. Readline knows that if I use
"ctr-left", it should jump the cursor one word to the left. Yes, it is
not easy, but that's what readline is about, IMHO.
