ZSH completion

[Anonymous bin ich <ichbinanon@xxxxxxxxx>]

Hi all!

Currently when I press tab, Zsh automatically completes the word and
shows a list of alternatives, like this:

% cd /m<TAB>
->
% cd /media
/media /mnt

I want Zsh to stop completing until I press tab for a second time.
Something like this:

% cd /m<TAB>
->
% cd /m
/media /mnt

Next tab will start filling in my command. How is it possible?
