Pretty sure you’re talking about the Svalboard. I don’t think it uses chunks of words though. Each finger has access to 5 keys and you can map any layout. https://svalboard.com/

But maybe you’re thinking of stenography where you have fewer keys but you press them in combinations (chords) instead of individually. That looks crazy fast. https://youtu.be/7jVXrX5TDk4 https://www.artofchording.com/introduction/#stenography

I played through kotor 1 and 2 recently and experienced a lot of crashes. Eventually made it through, but prepare for some frustration.
