When Balloon Help is on, balloons will appear which tell you about anything you point to on the screen. You don’t need to click, just point. When help is turned on, every point, click, and drag works exactly as it normally does.
To turn Balloon Help ON chose “Show Balloon” in the Help menu.
To turn Balloon Help OFF chose “Hide Balloon” in the Help menu.
Mmmmm, System 7:
