javascript to test mouse cursor direction, speed, Mouse middle click test, change cursor...

Hello Seb-Daubert Excellent example and very useful, bringing together a lot of information. Thank you very much.
At the moment, I can't think of any use for “mouse speed or distance or middle click”, but maybe I will 😀. On the other hand, I've been exploring ways of executing JScode with other triggers, or provoking actions when the state of the cursor changes or when it modifies variables. There are lots of possibilities here.

Love that Seb thanks for sharing
