+ * To complicate things further, the middle button keys sequence
+ * is different from the odd press and the even press.

+ * 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:
