+Default: 20. Property: "Evdev Third Button Emulation Threshold".
+.TP 7
+.BI "Option \*qGrabDevice\*q \*q" boolean \*q
+Force a grab on the event device. Doing so will ensure that no other driver
+can initialise the same device and it will also stop the device from sending
+events to /dev/kbd or /dev/input/mice. Events from this device will not be
+sent to virtual devices (e.g. rfkill or the Macintosh mouse button emulation).

+.TP 7
+.BI "Option \*qIgnoreRelativeAxes\*q \*q" Bool \*q
+.TP 7
+.BI "Option \*qIgnoreAbsoluteAxes\*q \*q" Bool \*q
+Ignore the specified type of axis. Default: unset. The X server cannot deal
+with devices that have both relative and absolute axes. Evdev tries to guess
+wich axes to ignore given the device type and disables absolute axes for
+mice and relative axes for tablets, touchscreens and touchpad. These options
+allow to forcibly disable an axis type. Mouse wheel axes are exempt and will
+work even if relative axes are ignored. No property, this configuration must
+be set in the configuration.
+.br
+If either option is set to False, the driver will not ignore the specified
+axes regardless of the presence of other axes. This may trigger buggy
+behavior and events from this axis are always forwarded. Users are
+discouraged from setting this option.
+.TP 7
+.BI "Option \*qCalibration\*q \*q" "min-x max-x min-y max-y" \*q
+Calibrates the X and Y axes for devices that need to scale to a different
+coordinate system than reported to the X server. This feature is required
+for devices that need to scale to a different coordinate system than
+originally reported by the kernel (e.g. touchscreens). The scaling to the
+custom coordinate system is done in-driver and the X server is unaware of
+the transformation. Property: "Evdev Axis Calibration".
+.TP 7
+.B Option \*qMode\*q \*qRelative\*q\fP|\fP\*qAbsolute\*q
+Sets the mode of the device if device has absolute axes.
+The default value for touchpads is relative, for other absolute.
+This option has no effect on devices without absolute axes.
+.TP 7
+.BI "Option \*qSwapAxes\*q \*q" Bool \*q
+Swap x/y axes. Default: off. Property: "Evdev Axes Swap".
+.TP 7
+.BI "Option \*qXAxisMapping\*q \*q" "N1 N2" \*q
+Specifies which buttons are mapped to motion in the X direction in wheel
+emulation mode.  Button number
+.I N1
+is mapped to the negative X axis motion and button number
+.I N2
+is mapped to the positive X axis motion.  Default: no mapping. Property:
+"Evdev Wheel Emulation Axes".
+.TP 7
+.BI "Option \*qYAxisMapping\*q \*q" "N1 N2" \*q
+Specifies which buttons are mapped to motion in the Y direction in wheel
+emulation mode.  Button number
+.I N1
+is mapped to the negative Y axis motion and button number
+.I N2
+is mapped to the positive Y axis motion.  Default: "4 5". Property:
+"Evdev Wheel Emulation Axes".
+.TP 7
+.BI "Option \*qTypeName\*q \*q"type"\*q
+Specify the X Input 1.x type (see XListInputDevices(__libmansuffix__)).
+There is rarely a need to use this option, evdev will guess the device type
+based on the device's capabilities. This option is provided for devices that
+need quirks.

+ *   1 delayed left     - left pressed, waiting for right
+ *   2 delayed right    - right pressed, waiting for left

+ *   5 pressed right    - right pressed and sent
+ *   6 released left    - left released after emulated middle
+ *   7 released right   - right released after emulated middle
+ *   8 repressed left   - left pressed after released left
+ *   9 repressed right  - right pressed after released right
+ *  10 pressed both     - both pressed, not emulating middle
+ *
+ * At each state, we need handlers for the following events
+ *   0: no buttons down
+ *   1: left button down
+ *   2: right button down
+ *   3: both buttons down
+ *   4: emulate3Timeout passed without a button change

+ * left down to right down without anything in between, so all cases must be
+ * handled.
+ *
+ * a handler consists of three values:

+ *   1: action2
+ *   2: new emulation state
+ *
+ * action > 0: ButtonPress
+ * action = 0: nothing
+ * action < 0: ButtonRelease
+ *
