Hi,
Thank you for writing to Microsoft Community Forums.
I understand that the Microsoft all-in-one keyboard doesn’t support the 3 finger functionality, swipe gestures and palm rejection. However, this seems to be a good suggestion. I would encourage you to provide your valuable feedback in Feedback hub so that our development team can review your suggestions. To provide your feedback, please refer to the article Send feedback to Microsoft with the Feedback Hub app.
