The default positions of the buttons on both the two and three button mouse are labeled from left to right. Often left-handed user prefers to reconfigure the buttons so they are more suited for left-handed use. Figure 17-7 shows the default functions of the buttons for both mice.
Figure 17-8 shows the functions of the mouse buttons after changing the order for left-handed use. Now when the right mouse button is pressed, SELECT is activated, and when the left button is pressed, MENU is activated.
After you have made these changes in the mouse settings window, click SELECT on the Apply button to store the new settings.
