This uses the actual Braille alphabet with some symbols above the Braille "pattern" stating what they are. For example, the "LETTER SHIFT" pattern is shown as an 'up' arrow with a line at the bottom. Some patterns are shared between characters, like A-I and J, and, 1-9 and 0, respectively. The difference is that for the letters nothing precedes it, BUT, for the numbers it is preceded by the 'number' modifier (has a pound sign above it, #). The open-quotation marks and the question point also share the same pattern, and its placement determines what it is. For example, "HELLO" would be the quote marks, but 'what“' would be a question point. If there are any other questions, you know who to contact.
