Added fasd module, working ok with the incremental autocomplete. See info below.

Useful alias:
    a='fasd -a
    f='fasd -f
    z='fasd_cd -d'

    o='a -e open'
    v='f -e vim'

Word mode completion can be triggered on any command. Examples:
    vim f,sh<Tab>
    cd  d,<Tab>     # instead use 'z' for this

Shortcuts,
    bindkey '^X^A' fasd-complete    # C-x C-a to do fasd-complete (fils and directories)
    bindkey '^X^F' fasd-complete-f  # C-x C-f to do fasd-complete-f (only files)
    bindkey '^X^D' fasd-complete-d  # C-x C-d to do fasd-complete-d (only directories)
