Quicklypressing and releasing the buttons is called clicking. Sometimes, youwill need to do a double-click (clicking the same button twice quickly)or a right-click (clicking the right button quickly).The ratchet wheel in between the two buttons is added to provideeasier scrolling capability. By simply moving the wheel with your indexfinger, you can quickly move through multiple pages, lines, orwindows. The wheel may also function as a third button allowing youto quickly click or double-click an icon or a selected item.For information on how to connect your mouse, see “Connectingperipherals” on page 29.USB MousePS/2 MouseFor information on how to clean your mouse, see “To clean yourpointing device” on page 5.Note: If you are left-handed, refer to your Windows manual forinstructions on how to set up your mouse for left-handed use.
