I had written a Windows script for adding three-finger drag[0] that I use daily, perhaps it could provide some inspiration. Basically, it is an independent subscriber to RawInput messages that only keeps track of whether or not to send three-finger drag, and posts emulated mouse messages using SendInput. I have a few other scripts that each run as independent userland processes that only monitors their own trigger and nothing else. Tangentially, my TPMouse[1] script implemented inertia in a framerate-independent way so that it uses very little resource while having perfect simulation stability. A previous discussion where I explained the analytic derivation for this low-resource exact-solution damped inertia can be seen in [10] [0] https://github.com/EsportToys/PrecisionThreeFingerDrag/blob/main/finger.au3#L13 https://github.com/EsportToys/PrecisionThreeFingerDrag/blob/...
