I work with a similar platform called NetsBlox which is based on Snap! (sort of Scratch + Scheme) and there's some text-based search/input functionality, to the point where you can write a decent amount of it without your mouse at all. Might be worth looking into, Snap! has a lot of more advanced CS concepts Scratch doesn't AFAIK without making the skill floor noticably higher. It also focuses on creating custom blocks, which makes organization a lot easier.
