editrc: changing keybindings in /etc/editrc

Asterisk uses the editline library, and the keybindings can be configured in /etc/editrc. I have defined some of my own keybindins, some other are left to default values. How can I print the current keybindings in Asterisk? I am looking for something similar to what bindkey does in zsh. Also, how can I "unbind" a key, such as Ctrl+C ? And How would I create new keybinding that would bind Ctrl+D to exit/quit ? here is my current /etc/editrc: bind "^W" ed-delete-prev-word bind "\e[1;5D" vi-prev-word bind "\e[1;5C" vi-next-word bind ^[[5~ ed-search-next-history bind ^[[6~ ed-search-prev-history
