How to customize Readline keybindings of GHCi?

Question

I know GHCi supports Readline, and keybindings such as ^W and ^U work as expected.

I do wonder whether ghci support customization of keybindin

@ephemient's answer above also helps with newer builds of MySQL which have switched from readline to libedit. I used

$ ~/.editrc:
bind ^[[A ed-search-prev-history
bind ^[[B ed-search-next-history

to match my old version which used to work inside MySQL:

$ ~/.inputrc:
"\e[A":history-search-backward
"\e[B":history-search-forward

(my only annoyance now is that if I just want to scroll and not search, I have to type a "." first to match every line).
