I printed all the menu items and found out, that marquee zoom has a value "Zoom":
[cName:ZoomSubMenu, oChildren:[[cName:ZoomTo],[cName:Zoom],[cName:ZoomDrag] ....
Unfortunately app.execMenuItem("Zoom") doesn't execute this item and no error is shown. ZoomTo and ZoomDrag are executed.
What problem it might be here? I have the XIth version of Acrobat Pro.
var zoom = app.trustedFunction(function () {
app.beginPriv();
app.execMenuItem("Zoom");
app.endPriv();
console.println("Zoom!");
});
