* 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 Model 100'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/kaleidoscope/key_defs/keyboard.h
* https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs/consumerctl.h
* https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs/sysctl.h
* https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/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.
* keeping NUM and FN consistent and accessible on all layers
*
* The PROG key is special, since it is how you indicate to the board that you
* want to flash the firmware. However, it can be remapped to a regular key.
* When the keyboard boots, it first looks to see whether the PROG key is held
* down; if it is, it simply awaits further flashing instructions. If it is
* not, it continues loading the rest of the firmware and the keyboard
* functions normally, with whatever binding you have set to PROG. More detail
* here: https://community.keyboard.io/t/how-the-prog-key-gets-you-into-the-bootloader/506/8
*
* 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.
