+# The lookup keys are composed in:
+# 70-touchpad.rules
+#
+# Note: The format of the "touchpad:" prefix match key is a
+# contract between the rules file and the hardware data, it might
+# change in later revisions to support more or better matches, it
+# is not necessarily expected to be a stable ABI.
+#
+# Match string format:
+# touchpad:pnpid:<pnpid>:
+#
+# To add local entries, create a new file
+# /etc/udev/hwdb.d/71-touchpad-local.hwdb
+# and add your rules there. To load the new rules execute (as root):
+# udevadm hwdb --update
+# udevadm trigger /dev/input/eventXX
+# where /dev/input/eventXX is the touchpad in question. If in
+# doubt, simply use /dev/input/event* to reload all input rules.
+#
+# If your changes are generally applicable, open a bug report on
+# http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
+# and include your new rules, a description of the device, and the
+# output of
+# udevadm info /dev/input/eventXX
+# (or /dev/input/event*).
+#
+# Allowed properties are:
+# TOUCHPAD_HAS_TRACKPOINT_BUTTONS=1
+#
+# If the TOUCHPAD_HAS_TRACKPOINT_BUTTONS property is set, this
+# device has # the trackpoint buttons wired up to the touchpad as
+# BTN_0, BTN_1 and BTN_2. This affects the Lenovo X1 Carbon 3rd
+# and the *50 series (T450, T550, etc.)
