Query: Cross sections for the reactions $e^+ e^-\to K^0_S K^0_L\pi^0$, $K^0_S
  K^0_L\eta$, and $K^0_S K^0_L\pi^0\pi^0$ from events with initial-state
  radiation   We study the processes $e^+ e^-\to K^0_S K^0_L\pi^0\gamma$, $K^0_S
K^0_L\eta\gamma$, and $K^0_S K^0_L\pi^0\pi^0\gamma$, where the photon is
radiated from the initial state, providing cross section measurements for the
hadronic final states over a continuum of center-of-mass energies. The results
are based on 469~$fb^{-1}$ of data collected at or near the $\Upsilon(4S)$~
resonance with the BaBar detector at SLAC. We present the first measurements of
the $e^+ e^-\to K^0_S K^0_L\pi^0$, $K^0_S K^0_L\eta$, and $K^0_S
K^0_L\pi^0\pi^0$ cross sections up to a center-of-mass energy of 4~GeV, and
study their intermediate resonance structures. We observe $J/\psi$ decays to
all of these final states for the first time, present measurements of their
$J/\psi$ branching fractions, and search for $\psi(2S)$ decays.
