It was previously known as Grade 2 braille. Contracted (grade 2) braille is used by more experienced braille users.

Is Braille a word or letter?
Braille doesn’t have a separate alphabet of capital letters like standard print. Instead, there’s a “code” that tells the reader the next letter is capitalized. That “code” is a dot-6. And, if you want to capitalize an entire word, you put 2 dot-6’s in front of the word.
