RawInputViewer VS TPMouse

You'll need to tick the "Other Human-Interface Devices" checkbox and untick Mouse and Keyboard, so that you don't get the driver-synthesized SendInput mouse reports flooding the outputs

If that fails still, then I suspect that your RShift key in fact just sends a normal LShift scancode. In which case, would you mind verifying it by running https://github.com/EsportToys/RawInputViewer and tell me what the Make Code and VKey Code are when you press the respective L/R shifts?

Hi, my open-source app RawInputViewer allows you to view the raw data contents of what a game "sees" when they use the Rawinput API.

And for Windows, my https://github.com/esporttoys/TPMouse was inspired by warpd itself but focuses more on the intuitive usability of direct cursor control via inertia/momentum.

You may be interested in how I did my Windows script for adding three-finger drag[0].

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, not sure if this might serve for some inspiration, but 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]

With the TPMouse script I implemented the activation shortcut as LShift+RShift+ which I felt had a nice balance between deliberateness and easy-to-reach (since you are using it with your hands on homerow).

Though because some keyboards have key rollover issues with using both Shifts, Capslock+ is also allowed as an alternative activation shortcut.

I personally use AutoIt a ton as a super fast way to quickly prototype GUIs. It's basically a really simple entrypoint for WinAPI.

Shameless plug: my script for emulating a trackball with your keyboard [0], and my tray app for quickly tweaking your cursor speed (usually for when I'm drawing something)[1]
