Click the letters on the keyboard to type, left arrow key is to backspace, and space is to... well, space. There is a forum topic about this: http://scratch.mit.edu/forums/viewtopic.php?pid=23368#p23368 I saw chalkmarrow's excellent "katakana keyboard v. 1.1", and I wanted to make my own but with English characters. This clickable keyboard has only one sprite and one script. Coding is not the best but this is my first attempt at a one sprite project. The keyboard works very well, as long as you keep the mouse centered near the letter you want to click. This was done in less than one hour.
