The tablet has three touch-pad buttons on the top right of the screen.

- Wrench: opens the Wacom tablet options and properties
- Keyboard: opens a (slightly inconvenient) keyboard on the screen
- Menu: general tablet options that don't usually need to be changed (eg. screen brightness)
You can also access the tablet properties from System Preferences:

Choose the device that you want to change the properties for at the top of the window under 'Device'.
Use the dropdown menus for each key to choose the function.

Click 'Default' to return all of the values back to the default settings.
