    /* Configurable keymap for Minivan layouts 44, 45, 46 keys.  
     * May work for 12×12×12×[11-12] keys as well.
     * Configuration in ./user_config.h
     */

  /* Overview of the code
   *
   * The base layers are in separate files;
   * process_record_user(), unicode macros are defined in unicode_macros.c;
   * accented characters are defined in unicode_weurope.h
   *
   * Unicode macros facilitate recomputing for re-computing the Dvorak with changed letters 
   * ('descramble'), and exist because space ran out for * XP(…).
   *
   * The led color code might be a bit hairy, due to speed/count middle led overlapping layer color. 
   *
   *  Preprocessor indentation: # always in column one, #includes and #defines
   *  are most to the left unless nested, except in the user configuration
   *  block where room is left for a ‛//’. Logical stuff (#if etc) is
   *  indented from column two, and then in each nesting goes 4 more spaces
   *  to the right, so in between the normal code indentations. There should
   *  be a newline above and below logical statements. This makes preprocessor
   *  statements stand out, while giving more information in each statement.
   *  C indentation: trying to follow QMK standard.

/* Definition of the additional arrow cluster with optional navigation keys, for the 'arrow' hardware layout.

 * By default what becomes the up-arrow (row 2, 2nd key from right) is a no-action key on this layer,
 * which can be displaced without worry.
 * Keys that are displaced for the larger arrow cluster with navigation keys, get moved to the second definition

 *
 * Only the version where the triangle arrows are defined for the left hand, or the version where the flat line

 * There are several configurations, worked down in order to keep this mess under control.

     * Layer _PAD: Option for a different _PAD layer in the common layers system.
     *             This variety resembles the square layout of a numerical keyboard.
     *             It is different from one of the Numpad Base layer compile options, in that
     *             it only has a number pad for the right hand. It is also different in featuring
     *             modifiers, and the overall layout is sligthly different (Enter, = symbol).
     *
     *             ‛Tab’ on key 3 left hand is the same as the other _PAD layer option (with the
     *             numbers in a line, equal to the _NSY layer), to retain the same ability to
     *             type Control-Tab. It seems better to have RAlt in its usual place, Enter in
     *             its usual place, than to strictly follow a standard numeric keyboard layout
     *             (which puts Enter somewhere on the right, row 1). It seems easy enough to
     *             type Enter on this key as well, even with the right hand. Numlock is also
     *             in its usual place. Note that ‛Del’ on the left, row 1, is not a numbers pad
     *             Delete/Dot key, but standard Delete, also in the usual place.
     *
     *             This is probably the better one of the square layout numpads, unless you have a use
     *             for the two hands version. This is also available on ‛Base’ Numpad.
