+#+Title: Samuel's Literate QMK Config
+#+PROPERTY: header-args :tangle ~/qmk_firmware/keyboards/planck/keymaps/samuel/keymap.c
+
+This is my qmk firmware for my keyboard. I grew tired of organizing the keycode
+array in plain text so I made it a literate .org file. I've never done this
+before, so bear with me.

+This is my "pretty" org mode organized table for my main dvorak layer. If you
+don't use org mode, it won't be that exiting, but if you enjoy working in org
+mode, you can edit this table directly, and this file is tangled to the actual
+keymap. No more organizing spaces or converting to and from comments.

+I tried to keep my layout bare bones, just what would be available on a normal
+keyboard, minus some keys I never used. The bottom left copies a normal
+keyboards symbols from shifted numbers, and the rest is placed where convenient,
+with some considerations for one handed use, hence the shortcuts in the top
+left.

+But wait, we are missing several important keys!? yes, well, the modifier keys
+all do other keys when tapped. More about that in the keymap section.
+
+* Keymap Conversion in Python
+
+This python can convert that table into the array needed for the keymap file. It
+simply prepends every key with "KC_". I used to use a dictionary to convert some
+keys from the table into qmk keycodes, but the double convertion was
+unneccessary so I simply prepended all my macros with KC and moved all the
+implementation to the `process-user-input` function.

+assumed. My natuaral typing style experiences no delays from my method.

+
+The function that filter's user inputs and applies macros, the begginning is
+pretty basic, setting our main layer and configuring our secondary layer.

+
+*** Alt  and ()
+
+Left and right alt are ( and ) when tapped. I put them on alt instead of a more
+conveniant key like control because parentheses do not need to be shift modified
+ever, unlike some other tap keys seen in the next sections.
+
+#+BEGIN_SRC C :noweb yes
+case KC_T_LALT:
+if (record->event.pressed) {

+ }
+return false;
+break;
+
+#+END_SRC
+
+*** Gui  and `\
+
+I place gui in the bottom corner because I believe it is the hardest key to
+reach, so gui seemed like a good fit for a dedicated key that I never want to
+have to spam. For tap keys, I used equally unused keys that are not apart of the
+number pad or shifted number keys.
+
+#+BEGIN_SRC C :noweb yes
+case KC_T_LGUI:

+ }

+
+*** Ctrl and []
+
+Left and right control are [] respectively when they are tapped, making { and }
+also very convenient.
+

+  mod_press(KC_LCTL, 4);

+ } else {
+  mod_lift(KC_RBRACKET, KC_RCTL, 5);
+ }
+return false;
+break;
+
+#+END_SRC
+
+*** Shft and =-
+
+I place shift on the home row, so having '-' right of my pinkie is standard, and
+it only felt natural to put its opposite, '=/+' on the other side. I put an
+extra one on the right side in the secondary layer for the num pad.
+
+#+BEGIN_SRC C :noweb yes
+case KC_T_LSFT:
+if (record->event.pressed) {
+  mod_press(KC_LSFT, 6);

+ }
+return false;
+break;
+
+#+END_SRC
+
+*** Rise, DEL, and /
+
+I use the top corners as rise because I decided that I do not like using layers
+with my thumbs. It feels uncomfortable to hold keys down with the side of my
+thumb, and backspace, tab, enter, and spacebar keep them satisfied. My pinky is
+for holding modifiers, so it makes sense to put the layer key with the other
+modifiers. Both my left and right layer keys activate the same layer which also
+makes sense to me. You wouldn't want left and right shift to do different things
+
+I used to have escape in the top left, but I use delete a lot more, and putting
+escape under a layer has not been a problem at all. I put / in the top right
+corner again mimicing a standard dvorak keyboard.
+

+ }
+return false;
+break;
+
+#+END_SRC
+
+*** EZ keys
+
+I use ctrl+shift+arrows keys a lot, so when the layer key is pressed they became
+lazy versions of themselves with control and shift already pressed.
+
+I also added undo, copy, paste, and cut to be easily available with only the
+left hand like on a qwerty or colemek keyboard.
