gourdo1's GMMK Pro ANSI layout
This Windows-centric layout is based on Jonavin's GMMK Pro layout with several additions, modifications, a tweaked keymap, updated layers and expanded RGB controls.
Features:
Core Functionality
- VIA support enabled (added Mar 16, 2022)
- Most default Glorious shortcuts enabled
- N-key Rollover (NKRO) -- toggled with FN+R
- Gaming mode (FN + Win-key) locks out Win-key as well as double-tap Shift Capslock; Also RGB highlights WSAD and nearby gaming related keys
- Caps Word enabled: To capitalize the next word only, press and release both left and right shift keys at the same time. (added Feb 25, 2022)
- Multi-monitor app moving shortcuts: FN + [,] (square brackets) to move current app window to next monitor (added Apr 11, 2022)
- Domain shortcuts: FN+.=".com", FN+O="outlook.com", FN+Y="yahoo.com", FN+H="hotmail.com", FN+G="gmail.com". (added Apr 7, 2022)
- Capslock toggled by double tap of Left Shift key or FN + Capslock (RGB green highlighted)
- Fn-Backslash for Bootloader mode
- Home key on F13, Del key right of Backspace
- Insert accessible via Shift-Backspace (so shift delete still works in Windows Explorer)
- PrtScrn, Scroll Lock, Pause/Break are top right on the keyboard: Fn+F11, Fn+F12, Fn+F13
- Colemak key layout support (Layer accessible via Left Shift + turn Encoder clockwise until side LEDs light up purple)
- Double tap ESC any time to revert to base layer (added Feb 26, 2022)
Numpad + Mouse Keys (Capslock key)
- Overlay numpad + Mouse Keys are accessed through Capslock key hold (temp) or double press (locked) with RGB highlighting
- This layer disables much of the keyboard, except X/C/V for cut/copy/paste, WASD for cursor, Q/E for PgUp/PgDn, cursor keys become mouse keys, surrounding keys become mouse buttons and all number keys become numpad versions (so Alt char codes work regardless of which set you use)
- Fn & N keys light up orange if system numlock is off (inverted status), indicating numpad keys will not deliver expected output (FN + N to toggle)
- Double zero on comma key.
- Mouse Keys allow you to use the mouse without taking your hand off the keyboard. (added Mar 15, 2022)
- Mouse controls are: Cursor keys = move mouse; RShift = button1, End = button2, RCtrl = button3, PgUp/PgDn = Scroll wheel
- Mouse Keys can also be accessed as a standalone layer by Left Shift-turning the Encoder until the cursor keys light up green
Encoder Functionality
- Default knob turn changes volume; button press toggles mute
- Exponential encoder - quick repeated volume up doubles increase; quick repeated volume down triples decrease (added Feb 17, 2022)
- FN knob turn changes RGB idle timeout
- holding Left Shift changes layers
- holding Right Shift navigates page up/down
- holding Left Ctrl navigates prev/next word
- holding Right Ctrl changes RGB hue/color
- holding Left Alt changes media prev/next track
Global RGB Controls
- RGB backlight lighting effect: FN + up/down
- RGB backlight effect speed: FN + left/right
- RGB backlight hue cycle: FN + A/D
- RGB backlight brightness: FN + W/S
- RGB backlight saturation: FN + Q/E (added Feb 4, 2022)
- RGB backlight night mode toggle: FN + Z (indicators still work)
- RGB backlight timeout: FN + Encoder or "-" and "=" (default 15 minutes) (updated Apr 7, 2022)
- indicators in FN layer using RGB in F-key and number rows to show the current timeout in minutes
- RGB indicators on left side LEDs: Capslock (green), Scroll Lock (red), and Num Lock not set (orange)
- FN + Z to turn off RGB backlighting; press again to toggle
Advanced Controls
- FN + \ to get to bootloader mode
- FN + [ESC] to clear EEPROM (then unplug and re-plug) (added Apr 11, 2022)
- FN + R to toggle N-key Rollover (added Apr 11, 2022)

rules.mk Options
STARTUP_NUMLOCK_ON = yes - turns on NUMLOCK by default
ENCODER_DEFAULTACTIONS_ENABLE = yes - Enabled default encoder functions
TD_LSFT_CAPSLOCK_ENABLE = yes - This will enable double tap on Left Shift to toggle CAPSLOCK when using KC_LSFTCAPS
IDLE_TIMEOUT_ENABLE = yes - Enables Timer functionality; for RGB idle timeouts that can be changed dynamically
INVERT_NUMLOCK_INDICATOR - inverts the Numlock indicator, LED is on when numlock is off -- numlock interferes with numpad keys, so should generally be off when numpad layer is active.
COLEMAK_LAYER_ENABLE = yes - Enable optional 5th layer for COLEMAK layout. Use Shift + encoder to enter 5th layer.
