4. Switched Mice

Some mice, not usually the cheapest ones, have a switch on the bottom marked `2/3'. Sometimes this may be `PC/MS'. In this case the `2' setting is for 2 button Microsoft mode, and the `3' for 3 button MouseSystems mode. The `PC/MS' switch is a bit more complicated. You will probably find the `MS' setting is for Microsoft, and the `PC' is for MouseSystems. You may find the `PC' setting described as ps/2 mode, but it should do MouseSystems as well. If you have such a mouse, you can switch the switch to `3' or `PC', put the MouseSystems settings in your XConfigs (see below) and the mouse should work perfectly in 3-button mode.
