This is directly from Logitech:http://logitech-en-emea.custhelp.com/
"Logitech MouseWare Software:
1. Right click on the Logitech white mouse icon in the System Tray and select "Mouse Properties".
2. Click on the "Buttons" tab and your pointing device should be shown. If you have more that one mouse connected, select the mouse you wish to program by clicking on the "Devices" tab, and select the mouse you wish to program from the drop down menu, then go back to the "Buttons" tab.
3. Scroll down the list of buttons and select the button you wish to program, and click on the function to highlight it.
4. Now click on the "Modify" button. A "Modify Button Function" box will appear with a drop down menu. Select the button assignment you wish to use and click the "OK" button. Now click the "Apply" button to save your changes.
Using the "Keystroke" button assignment.
If the button assignment or keyboard command you want is not listed under the button assignments, you may want to use the "Keystroke" button assignment. Using the MouseWare steps above select Keystroke under Step 3. The "Keystroke Assignment" box appears. Click your mouse cursor into the box that states "Unassigned". Now press the key or combination of keys you wish to use and click the "OK" button. The function should now be displayed in the current list of button assignments. Click the "Apply" button then the "OK" button."
Hopefully this will help. Please let me know if it doesn't.
