On a Surface Book 2, I am able to zoom web pages in Chrome-based browsers using a single point of touch and the pen simultaneously. I believe the pen and touch input are interpreted as “multitouch”. To activate this, the host machine must uncheck “Ignore touch input when I’m using my pen” under Settings -> Devices -> Pen & Windows Ink. This works in Chrome-based browsers, but not Firefox or drawing apps.
This is a nice feature, because at least two points of multi-touch are essential on Windows tablets for web browsing, OneNote, and similar drawing applications.
Windows 10 Driver v1.0.39 (Windows 10 Desktop)
Windows 10 Viewer v0.0.23.0 (Surface Book 2)
The Windows 10 Viewer performs very well. Is multi-touch input in consideration specifically for the Windows 10 Viewer?
