Yes, that's pretty much it.  You use the readline key binding syntax to
bind a string to a key sequence using a separate keymap.  Then you bind
that key sequence in the active keymap to a function that will look up
the string in the alternate keymap and execute it as if run by `eval'.
The READLINE_LINE and READLINE_POINT variables allow that command to
modify the line.  It's not a perfect fit to what readline could provide
`natively', but it's close.
