Though there are not many left handed computer users, it is a bit difficult for a left handed person to use a computer mouse. From Windows 98 onwards it is possible to configure the mouse to suit a left handed user. Once you configure your mouse the left handed users can swap the functionality of a left and right mouse button. To do this follow these steps:
