Introduction
As the whole world — or the whole FileMaker world at any rate — knows by now, last week saw the release of FileMaker 2026 with a number of compelling new features, as well as improvements to existing features. And almost immediately an abundance of well-written, insightful articles appeared, blossoming like a field of springtime flowers to serve as trusty guides, including…

Meanwhile in this article we’re going to focus on one new feature, and its relevance to the collection of techniques known as virtual list. To quote from the FM 26 release notes:
The Select Window, Close Window, Move/Resize Window, and Set Window Title script steps now support selecting a window by UUID, making it possible to uniquely identify a window even if multiple windows have the same name or if the window’s name has changed. You can use the new Get(WindowUUID) function to get the UUID of the currently active window.
