function ffz() {
    fzf --preview '[[ $(file --mime {}) =~ binary ]] &&
                 echo {} is a binary file ||
                 (highlight -O ansi -l {} ||
                  coderay {} ||
                  rougify {} ||
                  cat {}) 2> /dev/null | head -500'
}

The ffz function creates a preview page to the right side of the window so we can see the contents of the file. It also pipes the results through one of three code highlighters: highlight, code ray or rougify, which allows the previews to have Code highlighting as well. Pretty neat!
