Hello!

  In attach run-help helper for linux's ip command, simply copy it to your
  $fpath and run

    autoload -Uz run-help-ip

  After that you can use run-help command for getting man
  for certain ip subcommands:

  # ip -o addr<F1>
  # run-help ip
  ip is /sbin/ip
  IP-ADDRESS(8)                        Linux                       IP-ADDRESS(8)

  NAME
       ip-address - protocol address management
  ...



  I hope function will be the useful.
