This On Screen Keyboard was made for Blue OS, in OS Wars. Please leave your feedback in the comments below. Missing features - Text Engine, and the keypress functionality. I'm adding both of those things soon. Scratch is entering a new age, the age of mobile devices. Because scratch is now based on WebGL, this means that you can run projects through mobile browsers like Chrome, Firefox, Puffin, and Brave. With mobile being a thing now, you can't use a keyboard on projects unless you have a Bluetooth keyboard. This keyboard is meant to be embedded into a Scratch project to allow users to type as they normally would.
