/** This 'enum' is a list of all the macros used by the Model 01's firmware

    These are the names of your macros. They'll be used in two places.
    The first is in your keymap definitions. There, you'll use the syntax
    `M(MACRO_NAME)` to mark a specific keymap position as triggering `MACRO_NAME`

    The second usage is in the 'switch' statement in the `macroAction` function.
    That switch statement actually runs the code associated with a macro when
    a macro key is pressed.

/** The Model 01's key layouts are defined as 'keymaps'. By default, there are three
    keymaps: The standard QWERTY keymap, the "Function layer" keymap and the "Numpad"
    keymap.

    Each keymap is defined as a list using the 'KEYMAP_STACKED' macro, built
    of first the left hand's layout, followed by the right hand's layout.

    Keymaps typically consist mostly of `Key_` definitions. There are many, many keys
    defined as part of the USB HID Keyboard specification. You can find the names
    (if not yet the explanations) for all the standard `Key_` defintions offered by
    Kaleidoscope in these files:
       https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_keyboard.h

       https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_keymaps.h

    Additional things that should be documented here include
      using ___ to let keypresses fall through to the previously active layer
      using XXX to mark a keyswitch as 'blocked' on this layer
      using ShiftToLayer() and LockLayer() keys to change the active keymap.
      the special nature of the PROG key
      keeping NUM and FN consistent and accessible on all layers


    The "keymaps" data structure is a list of the keymaps compiled into the firmware.
    The order of keymaps in the list is important, as the ShiftToLayer(#) and LockLayer(#)
    macros switch to key layers based on this list.



    A key defined as 'ShiftToLayer(FUNCTION)' will switch to FUNCTION while held.
    Similarly, a key defined as 'LockLayer(NUMPAD)' will switch to NUMPAD when tapped.
