+
+// This keymap is designed to make it easy to type in a wide variety of languages, as well as
+// generate mathematical symbols (à la Space Cadet).
+//
+// LAYER MAGIC (aka, typing in many alphabets)
+//   This keyboard has three "base" layers: QWERTY, GREEK, and CADET. The GREEK and CADET layers
+// are actually full of Unicode points, and so which point they generate depends on things like
+// whether the shift key is down. To handle this, each of those layers is actually *two* layers, one
+// with and one without shift. In our main loop, we manage modifier state detection, as well as
+// layer switch detection, and pick the right layer on the fly.
+//   Layers are selected with a combination of three keys. The "Greek" and "Cadet" keys act like
+// modifiers: When held down, they transiently select the indicated base layer. The "Layer Lock" key
+// locks the value of the base layer at whatever is currently held; so e.g., if you hold Greek +
+// Layer Lock, you'll stay in Greek mode until you hit Layer Lock again without any of the mods
+// held.
+//   TODO: This system of layer selection is nice for math, but it's not very nice for actually
+// typing in multiple languages. It seems like a better plan will be to reserve one key for each
+// base layer -- maybe fn + F(n) -- which can either be held as a modifier or tapped to switch
+// layers. That will open up adding some more languages, like Yiddish, but to do this effectively
+// we'll need to find a good UI with which to show the currently selected layer. Need to check what
+// the melody96 has in the way of outputs (LEDs, sound, etc).
+//
+// ACCENT MAGIC (aka, typing conveniently in Romance languages)
+//   We want to support easy typing of diacritical marks. We can't rely on the host OS for this,
+// because (e.g.) on MacOS, to make any of the other stuff work, we need to be using the Unicode
+// input method at the OS level, which breaks all the normal accent stuff on that end. So we do it
+// ourselves. Accents can actually be invoked in two different ways: one fast and very compatible,
+// one very versatile but with occasional compatibility problems.
+//
+//   THE MAIN WAY: You can hit one of the "accent request" key patterns immediately *before* typing
+//   a letter to be accented. It will emit the corresponding accented Unicode. For example, you can
+//   hit fn-e to request an acute accent, followed by i, and it will output í, U+00ED LATIN SMALL
+//   LETTER I WITH ACUTE. These "combined characters" are in Unicode normal form C (NFKC), which is
+//   important because many European websites and apps, in particular, tend to behave very badly
+//   (misunderstanding and/or crashing) when presented with characters in other forms! The catch is
+//   that this only works for the various combinations of letters and accents found in the Latin-1
+//   supplement block of Unicode -- basically, things you need for Western European languages.
+//
+//   (NB: If you make an accent request followed by a letter which can't take the corresponding
+//   accent, it will output the uncombined form of the accent followed by whatever you typed; so
+//   e.g., if you hit fn-e followed by f, it will output ´f, U+00B4 ACUTE ACCENT followed by an
+//   ordinary f. This is very similar to the default behavior of MacOS.)
+//
+//   THE FLEXIBLE WAY: If you hit the accent request with a shift -- e.g., fn-shift-e -- it will
+//   instead immediately output the corresponding *combining* Unicode accent mark, which will modify
+//   the *previous* character you typed. For example, if you type i followed
