WizMouse is a free and lightweight Windows application that enables a simple but effective trick: the ability to scroll the contents of a window that is under your mouse cursor without shifting the focus to that window.
It may not seem like much, at first glance, but the ability to scroll a window without having to click on it and shift the focus of your current window is a huge time saver. Once WizMouse is installed simply mousing over any open window and engage your scroll wheel for instant scroll with no additional click or shift in focus necessary. You’ll get so used to it you’ll forget that it wasn’t built into Windows from the start.
