Script or action to activate global in SwatchColor

the full sample is in the scripting reference

//Creating a new spot color
// Creates a new spot color in the current document, then applies an 80% tint to the
color
if ( app.documents.length > 0 ){
var doc = app.activeDocument;
// Create the new spot
var newSpot = doc.spots.add();
// Define the new color value
var newColor = new CMYKColor();
newColor.cyan = 35;
newColor.magenta = 0;
newColor.yellow = 50;
newColor.black = 0;
// Define a new SpotColor with an 80% tint
// of the new Spot's color. The spot color can then
// be applied to an art item like any other color.
newSpot.name = "Pea-Green";
newSpot.colorType = ColorModel.SPOT;
newSpot.color = newColor;
var newSpotColor = new SpotColor();
newSpotColor.spot = newSpot;
newSpotColor.tint = 80;
}
