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.
