^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2620) * the sides buttons are pressed, it sends some keyboard keys events
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2621) * instead of buttons ones.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2622) * To complicate things further, the middle button keys sequence
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2623) * is different from the odd press and the even press.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2628) * 2nd time: left-click (press only)
