Ah. I use the standard emac'esque commands to move over by word. alt+b for back word, alt+f for forward word. Not at all intuitive... windows line movement commands win over emacs bindings form an intuitive perspective.

Also you don't need these to get up/down to work:

    "\e[C": forward-char
    "\e[D": backward-char

Those are for left/right arrows.
