“The Microsoft Surface keyboards have a trackpad that you can use like a mouse. This app lets you choose how the trackpad works on Touch Cover and Type Cover,” the app description reads. This app lets you control tap gestures as well as control scrolling. If for some reason this app does not detect your keyboard, simply make sure you have installed all the latest Windows Updates or hit “Refresh” in Devices and Printers. This app is available for download in the Windows Store for Windows RT users.
