    Hello,

    I have a script that creates a canvas with scrollbars and and I have a <Shift-MouseWheel> binding for it. This seems to fire on Windows but
    does nothing on Linux. I am not sure if this has to do with the way the
    Linux box is set up or if there is a different way of accomplishing the
    same thing on Linux.

    This is valid for the Tk versions 8.4 - 8.6 and 8.7a1 - 8.7a3. In Tk
    versions 8.7a4 and later, the set of mouse wheel events is the same on
    all windowing systems. See also the description of the scrollutil::addMouseWheelSupport command of my Scrollutil package. One
    of the benefits of using this package is that it handles these technical details automatically, thus easing the development of Tk
    version-agnostic applications.

    Thanks for the heads-up and the detailed info. It looks like ScrollUtil
    is the way to go.
