+# jonavin's GMMK Pro ISO layout
+# Thanks to RustyBrakes for the keymap adjustments and ISO Layout testing
+
+- Add Fn layer keys from Glorious Core mapping that's missing in the default qmk mapping
+- Add PrtScr, Scroll Lock, Break, NumLock to Fn layer
+- Implement Win key lock using Fn+Win like in Glorious Core firmware
+- Layer 2 mod on Caps Lock with double-tap to switch to this layer, double tap to switch back
+- Layer 2 provides arrows on WASD and additional nav keys + right hand numpad with 00; an be used for Alt Code entry
+- Layer 2 left spacebar Backspace
+- add double tap of Left Shift to toggle Caps Lock
+- additional encoder functionality
+    - FN Layer - change rgb idle timeout
+    - holding Left shift, change layers
+    - holding right shift, Navigate page up/down
+    - holding Left Ctrl, navigate prev/next word
+    - holding Right Ctrl, changes RGB hue/colour
+    - holding Left Alt, change media prev/next track
+    - default is change volume
+    
+- LED/RGB Functionality
+    - RGB idle timeout (default 5 minutes)
+        - Can be changed in FN layer with < and > or encoder
+        - setting to zero disables timeout
+        - indicators in FN layer using RGB in FN and number rows to show the timeout in minutes
+    - LED address location map as enum definition in rgb_matrix_map.h
+    - LED group lists for arrows, numpad, F row, num row, left and right side LEDs
+    - default startup in single mode with default colour 
+    - Capslock, Scroll Lock, and Num Lock (not set) indicator on left side LED
+    - Layer indicator on right side LED
+    - Fn key light up red when Fn layer activate
+    - Win Key light up red when Win Lock mode enabled
+    - Layer 2 activation lights up Numpad area
+    - Fn + Z to turn off all RGB lights except rgb indicators; press again to toggle
+
+rules.mk OPTIONS - Active features from userspace
+STARTUP_NUMLOCK_ON = yes
+    - turns on NUMLOCK by default
+
+ENCODER_DEFAULTACTIONS_ENABLE = yes
+    - Enabled default encoder funtions
+  
+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 Num lock indicator, LED is on when num lokc is off
+
+COLEMAK_LAYER_ENABLE = yes
+    - Enabled optional 5th layer for COLEMAK layout
+    - Use Shift and encoder to enter 5th layer, right led indicator lights up BLUE

+== Layout
+Based on the stock layout but making use of CAPS as FN similar to laptop keyboards.
+This frees up the left row for other uses (although not remapped yet).
+Since both Delete and Insert are used for coding they are part of the CAPS layer as well.
+
+The differences are as follows:
+
+=== Layer 0 (`_BASE`)
+Mostly stock + CAPS goes to layer `_MOV`.
+FN toggles the layer `_RGB`.
+
+=== Layer 1 (`_MOV`), accessed by pressing `CAPS` on layer `_BASE`

+
+== RGB light
+
+The code customizing RGB light usage is decribed here:
+
+* link:../../../../../../users/vitoni/readme.adoc[/users/vitoni/readme.adoc]
+
+When using  `RGB_DISABLE_TIMEOUT` addtional options are available:
+
+* `RGB_FADE_IN` makes the RGB lights fade in instead of setting the value/brightness to 100% (implicitly due to HSV including the brightness) when resuming after RGB lights have been turned off.
+Fade in occurs when the keyboard is initialized and when the RGB brightness has been changed (e.g. suspending, fade out, etc.).
+* `RGB_DISABLE_WITH_FADE_OUT` activates fade out before the keyboard is disabled by `RGB_DISABLE_TIMEOUT`.
+
+Parameters used to define the behavior are:
+[%header]
+|===
+|Key | Default | Description
+
+| RGB_MATRIX_MAXIMUM_BRIGHTNESS
+| 200 (&lt;= UNIT8_MAX)
+| Maximum assumed value for brightness.
+Used to calculate lead time for fade out before suspend timeout.
+
+|===
+
+`RGB_IDLE_TIMEOUT` enables fading out after being idle for the defined time and allows
+* `RGB_IDLE_BREATHE` also activates a brethe effect while idling.
+
+[%header]
+|===
+|Key | Default | Description
+
+|RGB_IDLE_TIMEOUT
+|4500
+|Time in milliseconds without activity before considered to be idle.
+
+|RGB_IDLE_MINIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` / 5
+|Brightness value RGB is dimmed to when starting to idle. +
+When breathing used as the lower bound of the brightness value.
+
+|RGB_IDLE_MAXIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` * 2/5
+|Upper bound of brightness value of the RGB light while breathing.
