I'm gonna create a "programming language" in scratch. I've only created the input system so far. Hopefully this whole language will be at least kind of useful. Just type in characters and they will appear. press ` for BACKSPACE. If a character like 'c' or 'v' keeps appearing, just press it again and it will stop. This is because you might have sticky keys enabled, or you may have pressed control or command.
It'd be really cool if people created scratch projects in MAPPAL. Beware: everything you type is automatically deleted once the green flag is clicked.
