Huh, I was picturing Regent more, like, drawing the letters with his finger in the bugs.
That would work too, and it’s possible you’re right, but it’d be way slower than a swipe-enabled bug keyboard.
Then again, the latter also requires more thought on Taylor’s part to interpret the swipes.
Okay, rereading the section, it does look like the asker was right here. This would explain why Taylor placed the bugs in a square. I think I just got confused by that at the time.
