The Synaptics TouchPad driver may also control other pointing devices attached to your system. If the Synaptics TouchPad driver is controlling more than one pointing device on your system, the Synaptics pages on the Mouse control panel will have a drop-down box listing all of the pointing devices that are controlled. You may set separate settings for each by selecting the appropriate device (settings which don’t apply to a particular pointing device will be grayed out).
Check the appropriate boxes in the Taps section of the Touch Properties Page for the tapping capabilities that you prefer:
Use the Touch Sensitivity slider to control how much finger pressure you must apply before the TouchPad responds. See Adjust the Overall Touch Sensitivity.
The Palm Check slider controls the TouchPad’s detection of accidental and unwanted pointing movement. In addition to detecting palm contact with the TouchPad, the TouchPad can ignore much of the accidental and unwanted pointer movement that may occur while typing (due to accidentally contacting your TouchPad). See Prevent Accidental Pointing While Typing for more details.
Disable this device
This checkbox will disable the selected device when it is checked. The control panel will prevent the user from disabling all pointing devices attached to your system.
