Switch the modes using the Setting Screen: Press the Home and then the 
Menu button. An options menu will appear. Select “Settings” and the Setting 
Screen will appear. Select Touch Sensor and put a check mark beside Mouse if you 
want to use mouse mode or uncheck if you want to use trackball mode.
Mouse Mode
Mouse Mode uses a pointer to select items on the screen and navigate the screens 
and menus. Just like using your computer’s mouse to move the pointer on the 
computer’s screen, you can move your finger across the Touch Sensor and move 
the pointer.
Moving the mouse pointer: Lightly drag your finger across the Touch Sensor in 
the direction you want the pointer to move.
Clicking an item on the screen: Use the pointer and Touch Sensor to click 
application icons and settings icons or type letters using the onscreen keyboard.  
Move the pointer to where it is over the item and press the Touch Sensor to click 
the item.
Double-Clicking an item: Quickly press the Touch Sensor twice to zoom and 
unzoom a picture in the gallery, for example.
Click and Hold: Use the Touch Sensor to activate additional features by pressing 
down and holding. You can add a new shortcut or widget to the Home screen by 
clicking and holding down the Touch Sensor until the dialog appears.
