The production of enutral kaons in e+e- annihilation has been measured for c.m. energies between 3.4 GeV and 7.6 GeV. Near 4 GeV the inclusive KS cross section shows an increase and structure similar to total hadron production. Roughly 40-45% of all hadronic final states contain kaons, except at 4.028 GeV and 4.415 GeV, where a significantly larger kaon fraction is observed.
