Space and B to switch between slides. OK this is this super cool code that I found in a book. Basically you draw out this graph with all the letters (Y and Z are combined) and then place the code word (with no repeating letters) along the first line or two, then line up the rest of the letters in order, skipping the letters used in the code word. Its super easy once you figure it out. the code is written out with the numbers on the left side coming first, so A is 15 in the example provided. The great thing about this code is that you can include other codes hidden inside this code. For instance you could write out the code backwards or upside down. 14-35-31-12-55!
some book I read (I don't remember the title)
