Some background is important to understand my keybinding choices -
1. I use modifier-less bindings wherever possible. Hydra and modal editing make up most of my interaction with Emacs.
2. I use Kmonad to have Space act as Control when held. This makes Control the modifier which disrupts the typing position the least. It is also held with the thumbs - the strongest digits - reducing fatigue. So if I must use a modifier, I use Control.
3. I use the Dvorak layout.
4. I've used Vim and Evil for the longest time, but I like Boon's movement layout best -
   * QWERTY IO move up and down
   * QWERTY KL move left and right in small units (characters), and
   * QWERTY J; move left and right in larger units (words or s-expressions)

   This has several benefits over HJKL -
   1. To move left, the wrist need not to be angled awkwardly to sit on QWERTY HJKL (which also means the keyboard tactile nub on J does not sit under the index finger),
   2. ...nor need the finger make an awkward jump to QWERTY H on each left-moving operation.
   3. The relaxed position of the fingers placed on a flat surface is a curl, not a line, which is reflected in Boon's default JIO; position.

* TODO dvorak [60%]
At first I decided to remap all Emacs, Boon, and Hydra bindings, but it turned out to not be my idea of fun. I wrote boon-dvorak, and let [most of] the others be.

(QWERTY) C-w, C-u, and C-h are probably best left as they are, since they are also present in other applications.

1. [X] M-n, M-p, -> M-r, M-c
2. [X] M-q -> M-'
3. [X] M--
4. [ ] multiple-cursors
5. [ ] boon-c-god is bound to "j", which emulates QWERTY "c", but the bindings after it do not. Thus, to input "C-c C-c", one must press "j c" in Dvorak. Yuck.
6. [ ] M-n M-n not getting bound to font-lock-fontify-block ?
7. [ ] binding C-d to keyboard-quit in the minibuffer

** TODO Hydra [0%]
I started off using Hydra for programming modes, when I noticed that Elisp, Common Lisp, and Scheme all had some semantically-analogous operations with different names, which could be abstracted away behind a generic interface. Then, around the time I got into using Org for literate programs, I added an Org hydra, and then a general hydra for frequently-used operations.

Add these common operations to the hydra -
1. [X] =enlarge-window=, =enlarge-window-horizontally=
2. [X] =save-buffer=, =kill-buffer=
3. [ ] switch to last buffer, such that pressing it twice brings you back to the original buffer. Bind to "m" (same key as the one to launch the Hydra), moving magit to "M".
   * Trickier to implement than I thought.
4. [X] =toggle-debug-on-error=
5. [X] "insert" hydra, for timestamps, dates; in Elisp, insert as strings; in Org, in angular brackets; etc
6. [X] remove duplication

The =initials= completion style is excellent! Instead of typing =(w-o-t-t|<TAB>)= to get =(with-output-to-temp-buffer|)=, you can just type =(wott|<TAB>)=.

But with =initials=, the desired completion is often buried in the results. That is where =prescient= shines - it remembers your input text and ranks previously-selected suggestions higher.

=intials= is great for code (or at least Lisp code), but I prefer =orderless= for command names. It is basically the same as Ivy/Counsel completion, as far as I can make out.
