Play with addDocumentNoUI
var doc = app.documents.addDocumentNoUI();
$.writeln(app.documents.length) // 0
var t = doc.textFrames.add();
t.contents = doc.name;
t.selected = true;
$.writeln(t.selected) // true
$.writeln(doc.selection.length) // 1
/*
$.writeln(app.selection.length) // error, no such element
app.paste() // error, no documents are opened.
// and you can not duplicate or move items from visible document to the NoUI document.
app.redraw(); // crush!
*/
doc.saveNoUI(File('~/desktop/NoUI.ai'));
doc.closeNoUI();
$.hiresTimer; // It seems with NoUI mode, will take less executing time, need more tests.
