I tried that and about a million other things in Ubuntu. When I hit tab I see options, but nothing I put in my .zshrc will allow me to use the arrow keys or anything else to navigate the completion list.

I am using oh my zsh but I tried turning it off and it didn't seem to matter.

Maybe only Mac users use zsh?

With the default oh-my-zsh config, you have to hit tab two times, for example ls<space><tab><tab>

Wow! I would have never thought of that.. lol

Thanks a lot.. works.
