Mouse Functions
Under Swap mouse buttons, you can switch the left and right mouse buttons. If you do this, you will then click with the right mouse button to select and open objects, and will click with the left mouse button to call up context menus.
Many mice are now equipped with a scroll wheel. If you have a Microsoft Intellimouse or another compatible model, you can specify what should happen when you turn the mouse wheel under Scroll wheel. Scroll by 3 lines is activated by default, but you can change this value. You can also set the wheel to Scroll one screen page per notch, or deactivate scrolling by selecting No scroll.
The section Set pointer automatically offers a very helpful function. When this option is selected, the mouse pointer moves to the highlighted button automatically whenever a dialog window opens so that you can click this button right away.
