Weylus is an Open Source app that allows your tablet to stand in as a touch screen for your PC.
Weylus can also control your mouse with your tablet, mirror your screen to your tablet, send keyboard input using physical keyboards, and provides hardware-accelerated video encoding. No apps except a modern browser are required on your tablet.
Weylus will be a great addition to your toolbag if you need to utilize a touch screen for a specific job or project. Set up is relatively easy and is outlined in detail at the project's repository.
KeyTweak is a simple utility that allows users to redefine their keyboard input signals. The functionality is made possible by a registry value first documented in Windows 2000 and still works on all operating systems, including Windows 10.
