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.
