+

+
+I use [Colemak Mod-DH][colemak-dh] as my layout, so this takes up most of the base of the keyboard.
+
+Perhaps strikingly, I opted for not putting Shift on the thumb,
+but recreating the "ordinary" one-on-each-side setup from the good old typewriter days.
+While I already have a key to access the `LOWER` (L1) layer with my left thumb,
+I had to sacrifice Shift so I could fit a key to the `RAISE` (L2) layer on the right thumb.
+This also jumps to the `ADJUST` (L3) layer when both `LOWER` and `RAISE` are held at the same time.
+I will gladly trade two layers for one Shift key.
+
+One of the most basic things—besides having layers—that one can do with QMK is [mod-taps][qmk:mod-tap].
+These are keys that act as modifiers when held, and as "ordinary" keys when pressed.
+For example, all of the `S+«key»` keys emit Shift when held and `«key»` when pressed.
+There is a slight delay between pressing the key and the press registering,
+since we have to wait for a possible tap,
+which keeps me from using modifiers on the home-row, as some people like to do.
+Likewise, the `M4+;` key acts as Super when held and as `;` when pressed.
+At this point, it is actually my main way to press the Super key,
+even though I don't find the real `M4` key particularly hard to hit with my thumb.
+Sometimes these things just happen,
+I suppose,
+though it may help that I press both outer keys of the top row (that is, `q` and `;`) with my ring finger
+instead of my pinky.
+
+The `A[]` and `C()` keys are utilising [tap dances][qmk:tap-dance],
+in order to do even more.
+Tap dances are very similar to mod-taps,
+only in addition to just differentiating between a "pressed" and a "held" state,
+QMK now also keeps track of *how often* a key has been tapped.
+So far, [my setup][qmk:slotthe:tapdances] here is quite basic;
+I only check whether a key was pressed once, twice, or is being held.
+This allows me to not need extra keys for parentheses,
+as they can fit on the modifier keys:
+
+ - `A[]`: Alt when held, `[` when pressed once, and `]` when pressed twice.
+ This one is especially neat, since tap dances play well with other modifiers,
+ so pressing `S-M1` once will result in `{` and pressing it twice gives `}`.
+
+ - `C()`: Control when held, `(` when pressed once, and `)` when pressed twice.
+
+I don't mind having the extra indirection for the respective closed delimiter,
+as [paredit][emacs:paredit],
+[puni][emacs:puni],
+`electric-pair-mode`,
+or a different package of choice usually takes care of inserting it.
+
+The `REP` and `AREP` keys make use of the [Repeat Key][qmk:repeat-key] functionality;
+basically, `REP` executes the key chord that was last pressed.
+On the other hand,
+`AREP` is an alternative, configurable, of "repeating" things;
+by default, it turns some directional movements
+around—e.g., `M-f` becomes `M-b`—but
+it can be made to pretty much input anything one wants.

+
+Guess which programming language I like based on this layer's [macros][qmk:macros] :).
+
+Crucially, keys that were "Shift when held,
+*something* when pressed" on the base layer retain the Shift part of that functionality.
+This is used for the commutativity of the modifier
+keys—i.e., it does not matter whether I press `S-L1-«key»` or `L1-S-«key»`—which
+would otherwise drive me insane.
+The same goes for all fall-through keys:
+keys that appear blank in the above layout.
+These aren't blocked or anything,
+just no new functionality is added
+so the key falls back to what's on the next lowest layer.
+In plain terms,
+the key to the left of `L3` will still be Control,
+as I can comfortably press that while holding down something with my left hand.
+The same can't be said for the Alt key,
+which is on the left hand by default,
+so a separate binding for it has to be created on the right hand.
+Thus,
+as the two don't commute,
+key chords involving the LOWER layer and Alt are to be avoided if possible.
+
+The `S-Ins` key is not some sort of tap,
+but actually just emits a Shift-Insert,
+which can be used to paste stuff from the [X11 primary selection][x11:clipboard].

+A relatively unspectacular layer,
+RAISE is mainly used for numbers,
+and number adjacent things.
+Some symbols related to this,
+like `=`, `+`, `*`, and `-`,
+are replicated from the LOWER layer.
+This is due to the above mentioned issues of inserting arithmetic.
+This layer also features \` and `'` quite prominently,
+as these are important for [CDLaTeX].
+Plus, putting `'` and `"` on this layer circumvents the difficult to hit key on the base layer.

+
+So far, only the seldom used F-keys are present here.
+As should be obvious, this is the least developed layer,
+and also the one that'll probably change the most in the future.
+Currently, I'm thinking of putting some XMonad specific bindings on here,
+which could even to free up the Super key to be used inside of Emacs
+for certain things—that would certainly be a worthwhile experiment.
+Other thoughts include things like volume and brightness controls,
+although this is less critical since my laptop keyboard is never far away.
+
+## Other features
+
+There are some features that aren't necessarily reflected in the keys themselves,
+yet are quite essential for day-to-day use.
+The TL;DR can be found in [rules.mk][./rules.mk].
+
+### [Key overrides][qmk:key-overrides]
+
+Quoting from the documentation
+
+> Key overrides allow you to override modifier-key combinations to send a different modifier-key combination
+> or perform completely custom actions.
+
+Some keys on the keyboard are quite hard to hit.
+On the default layout,
+one of these turns out to be the Tab key,
+which is nonetheless important in a lot of situations.
+Conveniently, Emacs interprets `C-i` as Tab, so there is less need to actually hit the "real" key.
+However, not all programs are quite so understanding—or old, I guess.
+With key overrides, one can send a real `TAB` whenever `C-i` is pressed;
+no special convention on how to interpret certain key chords required!
+I also rebound `C-m` to `RET` (with the same justification), and `S-BSP` to `DEL`.
+
+This is one of those features that I didn't know I needed,
+yet now couldn't live without anymore.
+I'm definitely looking forward to discovering new and interesting ways of using this!
+
+### [Autocorrect][qmk:autocorrect]
+
+This is a quaint little feature: auto-correct inside of your keyboard's firmware!
+I promise that it's not as bad as it sounds.
+It does not work automatically, thankfully, but is based off a given list of replacements.
+For example,
+
+ widht -> width
+
+would fire anytime one writes `widht`, which then gets replaced by `width`.
+This is based on (a trie of) the most recently pressed keys,
+so whenever one actually wants to write `widht`
+all that's needed is pressing, for example, any modifier during the insertion.
+
+As I've really just been trying this out for a laugh, my current word list is quite short:
+
+ :alot -> a lot
+ accesories -> accessories
+ accomodate -> accommodate
+ alledge -> allege
+
+In general,
+I think the solution to stop misspelling a word is not to remap key sequences on the firmware level,
+but to—you know—learn how to spell that word.
+Still,
+I can imagine at least one or two use-cases where something like this could be useful,
+so I figured it might be nice to make people aware of this features' existence.
+
+In addition—as I've found out on three separate occasions so far—using the words "auto-correct, but in firmware"
+makes people stare in utter disbelief and/or disgust at your keyboard.
+That alone makes this feature worth it.
+
+### [Caps Word][qmk:caps-word]
+
+Caps Word is a clever alternative to Caps Lock,
+which I enable by pressing both Shift keys together.
+After that,
+all of the letter keys are shifted,
+and `-` becomes `_`
+until a different key (excluding common sense ones like backspace) is pressed.
+This is very useful for, e.g.,
+writing long constants,
+as these tend to have capital names separated with underscores:
+writing `BOTH_SHIFTS_TURNS_ON_CAPS_WORD` has never been easier!
+
+One thing to note is that,
+while layer switching works just fine in "Caps Word mode",
+the [Tri Layer][qmk:tri-layer] feature does not seem to play nicely with it;
+i.e., the mode gets disabled when switching to these layers.
+This is also the reason why I have an explicit LOWER, RAISE, and ADJUST setup,
+instead of just using Tri Layer.
+One could fiddle with the `caps_word_press_user` callback,
+but it seemed much easier to just create one additional layer toggle instead.
+I haven't looked at how hard it would be to hack this into Caps Word,
+so maybe this is a future pull request.
