  # INSTRUCTIONS
  #
  #   To enable agent forwarding support add the following to
  #   your .zshrc file:
  #
  #     zstyle :omz:plugins:ssh-agent agent-forwarding on
  #
  #   To load multiple identities use the identities style, For
  #   example:
  #
  #     zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
  #
  #   To set the maximum lifetime of the identities, use the
  #   lifetime style. The lifetime may be specified in seconds
  #   or as described in sshd_config(5) (see TIME FORMATS)
  #   If left unspecified, the default lifetime is forever.
  #
  #     zstyle :omz:plugins:ssh-agent lifetime 4h
