Customizing the touch response mode

The touch response mode defines how your touch emulates the functions of a mouse.
For example, you can define a touch to produce a button down (pressing a mouse
button) or button up (releasing the mouse button). Touch modes also define how your
touch produces a mouse click and double click. TouchWare allows the following touch
modes:
Desktop (default)
Drawing
Button The system moves the cursor to the touch point and immediately generates a
Click
Lift-off The system moves the cursor to the touch point, but does not generate a
Touchdown

The system moves the cursor to the touch point, but does not generate a

mouse button down. You can slide your finger around the screen and your
movements are followed; however, the system generates mouse move events
only. Lifting your finger off of the screen generates a mouse button down. The

Drag is not supported; however lift-off mode is useful for applications that
requires greater accuracy.
