Actually loading the module is all you have to do. The problem was my
shell. zsh is capturing ^E as something other than the checkpoint signal.
I think I can bind the key to do what I want. Problem is ctrl-e is very useful
on the bash command line for us Emacs keybindings users... :)
it means "go to the end of the line". ctrl-a is the other direction.. Why
not ctrl-| for the checkpoint? I don't think anything uses that.
