+ * instead of buttons ones.
+ * To complicate things further, the middle button keys sequence
+ * is different from the odd press and the even press.
+ *
+ * forward button -> Super_R
+ * backward button -> Super_L+'d' (press only)
+ * middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
+ * 2nd time: left-click (press only)
+ * NB: press-only means that when the button is pressed, the
+ * KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
+ * together sequentially; instead when the button is released, no event is
+ * generated !
+ *
+ * With the command
+ * 10<xx>0a 3500af03 (where <xx> is the mouse id),
+ * the mouse reacts differently:
+ * - it never sends a keyboard key event
+ * - for the three mouse button it sends:
+ * middle button press 11<xx>0a 3500af00...
+ * side 1 button (forward) press 11<xx>0a 3500b000...
+ * side 2 button (backward) press 11<xx>0a 3500ae00...
