The prime purpose of the KatMouse utility is to enhance the functionality of mice with a scroll wheel, offering "universal" scrolling: moving the mouse wheel will scroll the window directly beneath the mouse cursor (not the one with the keyboard focus, which is default on Windows). This is a major increase in the usefullness of the mouse wheel.
Another (optional) feature involves the wheel button. Since the wheel button is not consistently used in Windows, KatMouse can use it for a kind of task switching: with a click of the wheel button you can push a window to the buttom of the stack of windows that is your desktop, making a recovered window the active window.
If your using KatMouse wheel button functionality, you can scroll most windows page wise by holding the wheel button over the window and clicking the left (up) or right (down) mouse button. If you hold the left or right mouse button, you'll get continuous, accelerating pagewise scrolling.
To push a window to the stack bottom, just click with the wheel button on the window (double click on 'always on top' windows). This works even while dragging something
with the mouse (i.e. copying files from one explorer to another). You can change the push button to be one the extended buttons of newer 5-button mice.
In the KatMouse properties dialog (available by right clicking on the KatMouse tray icon and clicking Settings ) you can choose individual wheel scroll settings for applications and windows. In the Applications tab, choose the applications executable file in the file dialog and set the desired scroll width by double clicking on the new entry in the list (screen shot ). After that all windows of this application will not scroll with the default scroll width, but with the individualized settings you made.
The same applies to the Classes tab: Here you can select the kind of window (its class) to customize (drag the crosshair to the window).
If the chosen window does not behave correctly you can disable the 'Window has wheel scrolling support' checkbox in its settings dialog. This will force KatMouse
to use a different, possibly less efficient approach to scrolling the window.
There are some applications which will not fully cooperate with KatMouse (older Microsoft Office versions for example). This usually results in the old scrolling behavior (scrolling window with keyboard focus) for this application.
