Does anyone know the name for the "object select tool" in java script to call it from tool pallet

selectTool("magicLassoTool");
function selectTool(tool) {
    var desc9 = new ActionDescriptor();
        var ref7 = new ActionReference();
        ref7.putClass( app.stringIDToTypeID(tool) );
    desc9.putReference( app.charIDToTypeID('null'), ref7 );
    executeAction( app.charIDToTypeID('slct'), desc9, DialogModes.NO );
};
