This System 7 extension allows you to grab an icon in the Finder, drag over to the Apple menu and then drop the icon you dragged there onto any of the items in the Apple menu!
E.g. grab a document's icon and drag it over a folder's alias in the Apple menu, and the document gets placed in that folder. Another example: grab a text document, drag it over Word's alias in the Apple menu, and Word will open it.
