Ido sets up thing slightly differently:
- Pressing Alt+j should throw you in the traditional switch buffer
- Pressing Alt+l should throw you into find file
But, if you have typed something and want to move around, Alt+j and Alt+l should still move the cursor around as you wish. I believe this is also true for the Alt+k and Alt+i keys. They should move in the history, as in typical IDO (the up/down arrow keys work the same for me).
To enable cycling using the Alt+j/l you can select it from the menu
Or in your .emacs use
(ergoemacs-require 'ido-prev-next-instead-of-left-right)
