doubletap_enable

----------------



sysfs: doubletap_enable



Controls whether TrackPoint doubletap events are filtered out. Doubletap is a

feature where quickly tapping the TrackPoint twice triggers a special function key event.



The available commands are::



                cat /sys/devices/platform/thinkpad_acpi/doubletap_enable

                echo 1 | sudo tee /sys/devices/platform/thinkpad_acpi/doubletap_enable

                echo 0 | sudo tee /sys/devices/platform/thinkpad_acpi/doubletap_enable



Values:



	* 1 - doubletap events are processed (default)

	* 0 - doubletap events are filtered out (ignored)



	This setting can also be toggled via the Fn+doubletap hotkey.
