Use arrow keys to move around your "text cursor" (what I call the line you see that shows you where your going to type) you need to try moving it to make it appear and to allow you to type Enter is delete because scratch can't detect backspace or any other special keys like shift, tab, and ctrl Click the ` (back quote key, top left of your keyboard under F1 with the tilde (~) symbol on the top of its key) to exit the script typer and show a copy thing, you have to click see inside, right click on the ScriptCopy list, and click "export", you can change the name but keep it as a .txt file, then go to the scripting engine (separate project), right click on the Script list, click "import" then select the file you downloaded from this project
Meant for a scripting engine made on Scratch (will update with engine name), can be used to type for whatever you want though, pretty much the same as notepad on Windows, but worse (for now)
