Thanks, Adam,
I've got it working now. Your sample code was calling document.getElementById("ctl_onchange").innerHTML, and I don't have that control.
Question: if there are multiple editors on the same page, how are the OnCommand events handled? Do we add:
editor2.ExecCommand=function(cmd,ui,val);
editor3.ExecCommand=function(cmd,ui,val);
etc.?
