Re: Getting selected layers by script (object refs, not indices!)

This would for example select each one of the originally selected Layers in turn.

One could use that as a starting point for some DOM operation but maybe one could instead stick with Action Manager code.

var myDocument = app.activeDocument;

myDocument.suspendHistory("operation", "main(myDocument)");
