Yes it can. Add something like this to your zsh config:

  zstyle ':completion:*:manuals'    separate-sections true
  zstyle ':completion:*:manuals.*'  insert-sections   true
  zstyle ':completion:*:man:*'      menu yes select

This does not work for me. If I type "tree -" and press [tab], nothing happens.

That's it. This thread sold me. Installing zsh now!
