How to read mouse wheel in windows 10

Hi Tom, the best way to do this would be to (ab)use KbQueues, which can record mouse axis motion, and sometimes as a 3rd axis also mouse wheel motion. This should work on Linux and Windows, but not macOS. See MouseMotionRecordingDemo.m for a starter: http://psychtoolbox.org/docs/MouseMotionRecordingDemo -mario

This is a bit of a hack, to work around deficiencies of MS-Windows api’s. On Linux, GetMouseWheel provides a more elegant solution.
