A Medley Interlisp session in which two windows are created and attached by evaluating the Lisp expressions:

(SETQ W1 (CREATEW NIL "Window 1")

(SETQ W2 (CREATEW NIL "Window 2")

(ATTACHWINDOW W2 W1 'TOP 'JUSTIFY)

Then the windows are manipulated as a unit by minimizing (Shrink), resizing (Shape), moving (Move), and closing (Close) both simultaneously.

Right-clicking in the main area of a window pops up the menu containing manipulation commands such as Close, Snap, Paint, Clear, and more. The menu is activated alternatively on the two windows. Middle-clicking on the title bar of a minimized window restores it to its original size.

This is a remote Interlisp Online session running in the cloud recorded on an ASUS Chromebox 3 under chromeOS.
