I see what you’ve done here, and it seems to get the information across. In the attached PDF, I’ve noted a few probable errors (mostly typos, and one note that, to the best of my understanding, the effect of a capitals indicator will not continue over/through the underscore).

Reading the rectangles (regular or ‘calculator rectangles,’ printed with rounded corners) within rectangles within rectangles, I admit to having struggled to unpack (hence my color-coding for proofreading in the attached file), but I think the information is there and consistent.

Braille on!
