So I doubt anybody else on Earth uses this phone anymore, much less this keyboard configuration, but overlooking that existentialism, I spent my morning making a .zip of the keyboard for CM13 Android Marshmallow. Everything works the same as with CM11, which is where I started this project. For some reason, the emoji keyboard pops out when you hit what's labeled the Shift key, but what I changed to the Alt key. Not a terrible nuisance, but maybe someone knows a solution. It's a great layout, especially the reintroduction of the Alt key, which can be clicked and combined with backspace to delete a whole line, good for those late night texts you should really think twice about before sending, or normal days.
