+# A keymap for Durgod Taurus K310/K320 that supports toggling between Mac and Windows
+
+Supports both ANSI and ISO layouts.
+
+Layer 0 : Standard layout (Windows)
+
+Layer 1 : Media control and Windows lock key (Windows)
+- Reusing Durgod's Original Media Control for Fn + F1 ~ Fn + F7
+- Fn + Windows to toggle Windows lock key functionality
+
+Layer 2 : System layer (Windows)
+- Fn + Menu + Esc : Bootloader mode
+- Fn + Menu + F1  : System Sleep
+- Fn + Menu + F4  : Turning Off System
+- Fn + Menu + F12 : Switch to Mac layout
+
+Layer 3 : Mac layout
+
+Layer 4 : Media control and Media lock key (Mac)
+ - Standard Mac Media keys for Fn + F1 ~ Fn + F12.
+ - Fn + F13 to toggle Media lock key functionality
+
+Layer 5 : System layer (Mac)
+- Fn + R-ALT + Esc : Bootloader mode
+- Fn + R-ALT + F4  : Shutdown/Sleep (Hold down on Mac)
+- Fn + R-ALT + F12 : Switch to Windows layout
+
+## Toggle between Mac and Windows layout
+
+You can switch between Mac and Windows layout by doing the following:
+- Hold down Fn + Menu (Windows Layout) or Fn + Right-Alt (Mac layout)  (These are the same physical keys)
+- Press F12
+
+The 'M' led will be lit when you are using the alternate layout.  By default Mac is the alternate layout.
+
+You can change the default & alternate layout by setting the following flags to either '_WBL'(Windows) or '_MBL' (Mac)
+- DEFAULT_LAYOUT (initial layout to use on boot)
+- ALT_LAYOUT (layout that will light the 'M' LED when active)
+
+For example, to configure Mac as the default layer, and Windows to be the alternate layout, compile with these flags:
+
+    make EXTRAFLAGS="-DDEFAULT_LAYOUT=_MBL -DALT_LAYOUT=_WBL" durgod/k3x0/k310:chimera
+
+## Windows key lock
+
+In windows layout, you can hold down Fn + Windows key to disable the Windows key while in locked mode.  The 'Lock' LED
+indicates if the Windows key is locked.
+
+This is similar to the stock K310/K320 Windows key lock functionality.
+
+## Mac Media Lock
+
+To switch between Function row and Media row in Mac layout, press Fn + PrtSc.  The 'Lock' LED indicator will be lit when in Media row mode.
+
+### Subsequent Flashing
+
+For repeating Flashing you have two options with this keymap:
+1. Use BootMagic
+- BootMagic Lite has been enabled with Assigned "Esc" key 
+- Unplug USB Cable
+- Holding Esc Button 
+- Plug in USB Cable, Keyboard should be in ST-Bootloader state
+2. Use key combination if using default keymap
+- Hold down Fn + Menu (Windows Layout) or Fn + Right-Alt (Mac layout)  (These are the same physical keys)
+- Press Esc.  Keyboard should go into booloader state.

+Supports both ANSI and ISO layouts.
+
+Layer 0 : Standard layout (Windows)
+
+Layer 1 : Media control and Windows lock key
+- Reusing Durgod's Original Media Control for Fn + F1 ~ Fn + F7
+- Fn + Windows to toggle Windows lock key functionality
+
+## Windows key lock
+
+You can hold down Fn + Windows key to disable the Windows key while in locked mode.
+The 'Lock' LED indicates if the Windows key is locked.
+
+This is similar to the stock K310/K320 Windows key lock functionality.

+# A keymap for Durgod Taurus K310/K320 that supports toggling between Mac and Windows
+
+Supports both ANSI and ISO layouts.
+
+Layer 0 : Standard layout (Windows)
+
+Layer 1 : Media control and Windows lock key (Windows)
+- Reusing Durgod's Original Media Control for Fn + F1 ~ Fn + F7
+- Fn + Windows to toggle Windows lock key functionality
+
+Layer 2 : System layer (Windows)
+- Fn + Menu + Esc : Bootloader mode
+- Fn + Menu + F1  : System Sleep
+- Fn + Menu + F4  : Turning Off System
+- Fn + Menu + F12 : Switch to Mac layout
+
+Layer 3 : Mac layout
+
+Layer 4 : Media control and Media lock key (Mac)
+ - Standard Mac Media keys for Fn + F1 ~ Fn + F12.
+ - Fn + F13 to toggle Media lock key functionality
+
+Layer 5 : System layer (Mac)
+- Fn + R-ALT + Esc : Bootloader mode
+- Fn + R-ALT + F4  : Shutdown/Sleep (Hold down on Mac)
+- Fn + R-ALT + F12 : Switch to Windows layout
+
+## Toggle between Mac and Windows layout
+
+You can switch between Mac and Windows layout by doing the following:
+- Hold down Fn + Menu (Windows Layout) or Fn + Right-Alt (Mac layout)  (These are the same physical keys)
+- Press F12
+
+The 'M' led will be lit when you are using the alternate layout.  By default Mac is the alternate layout.
+
+You can change the default & alternate layout by setting the following flags to either '_WBL'(Windows) or '_MBL' (Mac)
+- DEFAULT_LAYOUT (initial layout to use on boot)
+- ALT_LAYOUT (layout that will light the 'M' LED when active)
+
+For example, to configure Mac as the default layer, and Windows to be the alternate layout, compile with these flags:
+
+    make EXTRAFLAGS="-DDEFAULT_LAYOUT=_MBL -DALT_LAYOUT=_WBL" durgod/k3x0/k310:typhon
+
+## Windows key lock
+
+In windows layout, you can hold down Fn + Windows key to disable the Windows key while in locked mode.  The 'Lock' LED
+indicates if the Windows key is locked.
+
+This is similar to the stock K310/K320 Windows key lock functionality.
+
+## Mac Media Lock
+
+To switch between Function row and Media row in Mac layout, press Fn + PrtSc.  The 'Lock' LED indicator will be lit when in Media row mode.
+
+### Subsequent Flashing
+
+For repeating Flashing you have two options with this keymap:
+1. Use BootMagic
+- BootMagic Lite has been enabled with Assigned "Esc" key 
+- Unplug USB Cable
+- Holding Esc Button 
+- Plug in USB Cable, Keyboard should be in ST-Bootloader state
+2. Use key combination if using default keymap
+- Hold down Fn + Menu (Windows Layout) or Fn + Right-Alt (Mac layout)  (These are the same physical keys)
+- Press Esc.  Keyboard should go into booloader state.
