- configs/t4/default.cfg: Factory default for reference - configs/t4/mirrorwalk_nomcc.cfg: Mirrorwalk layout with system chords - configs/t4/mirrorwalk_nomcc.json: Tutor-compatible JSON for practice Key fixes for T4: - Use format version 0x0907 (Tuner generates 0x0107 which crashes device) - Include system chords for config switching and Bluetooth - Preserve layout letters when system chords conflict
Added the missing T14+F4R (N+S+4R) system chord with modifier 0x0701 to enable the Erase Bluetooth Pairs function on Twiddler 4. Also includes all 18 system chords from default config to ensure proper firmware function handling.
N+4L='0' (HID 0x27) interferes with N+S+4R system chord recognition due to a firmware quirk. Workaround is to switch to default config for Bluetooth erase operations.
Rebuilt config from JSON spec. Previous version from Twiddler Tuner was missing critical chords: - N+3R -> '3' (numpad digit) - Arrow keys (1M+2R+3L/3M/3R/4M) - Navigation (Home/End/PageUp/PageDown) - Delete, Tab, Escape, Insert - Math operators (/, +, *, =, -) Also removed 77 extra chords that weren't in mirrorwalk_nomcc layout (single-finger fallbacks, Ctrl+letter combos). Chords: 157 -> 105 (96 layout + 9 system)
