Sachee Dactyl Keyboard Layout (My Remix)

A three-layer layout for the Dactyl: QWERTY base with layer-tap thumbs, a number/symbol layer, and a navigation/media layer.

Design Notes

• Thumbs do the heavy lifting — layer-taps and mod-taps instead of a TG() toggle:
  • Backspace (tap) / NUM layer (hold) — left thumb
  • Space (tap) / NAV layer (hold) — right thumb
  • Enter (tap) / Ctrl (hold) — right thumb
  • Esc (tap) / Hyper (hold) — left pinky home position
• Arrows live on HJKL in the NAV layer — hands never leave home row.
• Symbols under the strong fingers in the NUM layer instead of bottom-row pinky reaches.
• RESET and Sleep are tucked into far corners so they can't be hit by accident.

Base Layer (_QWERTY)

`	1	2	3	4	5	6	7	8	9	0	=
Tab	Q	W	E	R	T	Y	U	I	O	P	-
Esc/Hyper	A	S	D	F	G	H	J	K	L	;	'
Shift	Z	X	C	V	B	N	M	,	.	/	Shift
ScrCap									[	]	\

Thumb clusters: transparent (pass through to base layer).

Custom Keycodes

#define KC_NUMBSP LT(_NUM, KC_BSPC)    // hold: num layer, tap: backspace
#define KC_NAVSPC LT(_NAV, KC_SPC)     // hold: nav layer, tap: space
#define KC_CTLENT MT(MOD_RCTL, KC_ENT) // hold: ctrl, tap: enter
#define KC_HYPESC ALL_T(KC_ESC)        // hold: hyper, tap: esc
// misc

#define KC_CAPP LGUI(LSFT(KC_4))       // macOS: capture portion of screen

Flashing Notes

1. Blank cells inside KC_KEYMAP become KC_TRNS via the #define KC_ KC_TRNS trick — if your fork of the Dactyl macro is picky about empty entries, replace the blanks with TRNS.
2. Layer-taps use the default 200 ms tapping term. If you get stray backspaces when holding for the NUM layer, add #define TAPPING_TERM 175 (or tune to taste) in config.h.
