Open examples.letter. Type and execute:
fileMenu.print ()
» true
Open two or three windows, one of which is system.verbs.builtins. Make sure that system.verbs.builtins is not the frontmost window. Now type and execute:
target.set (@system.verbs.builtins);
fileMenu.print ();
target.clear ()
» true
The contents of the system.verbs.builtins window prints regardless of what window is frontmost, demonstrating that the fileMenu verbs operate on the target window, not necessarily the topmost window.
