1 Overview
==========

☑ _Intuitive:_ Key placement follows what a 10 finger typist is used
  to on a regular keyboard. Similar keys meanings are on the same
  key in different layers, or the same finger, etc. See also chapter
  12, _Key associations._ Thumbs control the most used layer access.

☑ _Feature rich:_ Dual layout, with several standard layouts to choose
  from. Expanded character set. Measure typing speed and/or amount of text
  typed. Mouse control, media control, power control, Unicode encoding for
  several platforms. In total there are about 4 times as many key functions
  than on a regular keyboard.

☑ _Configurable:_ Choose between standard layouts (Qwerty, Dvorak, etc);
  additional hardware keys ‛command/south-paw’ and/or ‛arrow’; movement
  layer WASD or flat arrows/mouse; numbers pad similar to regular numbers
  and/or like a regular numbers pad; and other settings. Easy to add your
  own layers. See ![./user_config.h](./user_config.h)

☒ What it does *not* do: work on a computer set to a non-English language,
  such as German or French. (To add such functionality requires some work,
  but it seems it should be possible. See ![./todo.md](./todo.md).)

1.1 Hardware compatibility
==========================
This keymap functions on _Minivan_ hardware variants with 44, 45 and
46 keys.

It may be fairly easily ported to 12x12x12x[11|12|13] keyboards.

1.2 Software compatibility
==========================
This keymap relies on Unicode, in an attempt to avoid the 
“dead key” system for accented characters on many non-English keyboards.
You need to have Unicode input working on your computer.

On a Linux computer operating system, this keymap is designed to work
with this keyboard/language setting:

        > setxkbmap -layout us
        > echo $LANG
        `en_US.UTF-8`

If that works for you, you can type the most important characters in
the western European group of languages, native from the keyboard.

This keymap might not function as expected if you want to use a
different keyboard language setting in your operating system.

See also chapter 7 _Language support_.

2 'make' example
================
     … Download the repository, resolve software dependencies etc..
     … To change compile options: edit ./user_config.h (or `./minifan_config_compact.h`)
     > cd […]/qmk_firmware
     > make thevankeyboards/minivan:josjoha
     > su
     # dfu-programmer atmega32u4 erase
     # dfu-programmer atmega32u4 flash thevankeyboards_minivan_josjoha.hex
     # dfu-programmer atmega32u4 start

This “Mini*fan*” layout is explained in several readme files, with
links to the others files in this readme. The common system is explained
in this readme.md file. The options for the letters and number/symbol
layer pairs (two pairs in the dual layout) are explained in their
separate readme file, see immediately below. Compile options are detailed
in ![./user_config.h](./user_config.h)

3 Base layouts
==============
Layouts are presented here in a sort of simplified key caps view.  If a
base layer pair has its own user configuration options, they are located
in `./base_NAME.h`.

3.1 Normal layouts
------------------
These are layouts for commonly used configurations, such as Qwerty or Dvorak.

3.1.1 Qwerty
------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_qwerty_vc.jpg)

For the readme about the Qwerty version, see ➡ ![base_qwerty.md](./base_qwerty.md) ⬅

3.1.2 Qwerty with arrows on Base
--------------------------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_qwerty_basearrow_ve.jpg)

For the readme about this Qwerty variation, see ➡ ![base_qwerty_basearrow.md](./base_qwerty_basearrow.md) ⬅

3.1.3 Dvorak
-------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_dvorak_vc.jpg)

For the readme about the Dvorak version, see ➡ ![base_dvorak.md](./base_dvorak.md) ⬅

3.1.4 Dvorak² 
-------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_dvorak_descramble_vb.jpg)

Regular Dvorak for a computer already set to Dvorak.

For the readme about the Dvorak² version, see ➡ ![base_dvorak_descramble.md](./base_dvorak_descramble.md) ⬅

3.1.5 Colemak
-------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_colemak_vc.jpg)

For the readme about the Colemak version, see ➡ ![base_colemak.md](./base_colemak.md) ⬅

3.1.6 Workman
-------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_workman_va.jpg)

For the readme about the Workman version, see ➡ ![base_workman.md](./base_workman.md) ⬅

3.2 Special layouts
===================
These are unusual layouts. Most people will probably only want one of these on the ‛Alternate’ layout,
with a normal layout on ‛Default’. How this works is explained below.

3.2.1 Numbers pad
-----------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_numpad_single_va.jpg)

For the readme about the Numpad version, see ➡ ![base_numpad.md](./base_numpad.md) ⬅


3.3 Non-Latin languages
=======================

3.3.1 Hebrew
------------

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_hebrew_vc.jpg)

4 The common system
===================

![Minivan layout impression](http://socialism.nl/misc/minivan/minivan_keycapview_common_vc.jpg)

4.1 Layer access
----------------
The graphic below shows how layers are reached from the ‛Default base’ layer.

This seems to be the place where one is supposed to say: “This is simple”. 
It may look more confusing than it is. If you write down an alphabet A,B, ➡ Z,
made arrows from every key on a keyboard picture to one of the letters, it could
look just as confusing. When switching to a layer, you only think about where you
want to go.

![Minivan layout Image associations](http://socialism.nl/misc/minivan/minivan-default-base-layer-activation_2000_vi.jpg)

Each of the two base layers comes with its own second layer, typically
numbers-symbols. The other layers are used common between the default and
alternate base layers.  You can switch between the default base layer
(typically letters), and another base layer, the alternate base layer
(also typically letters), on the `_RAR` layer with key ‛Other Base’.

     ³) 'South paw' hardware configuration. Configurable, default shown.
     ⁴) 'Arrow' hardware configuration  Configurable, default shown.
     ³ ⁴) There are two more optional hardware keys, to make it easier to compile for
          a 12x12x12x11 or 12x12x12x12 layouts.
     ⁵) Left Shift when pressed with another key. Medium long: to toggle _PAD. Long: toggle _MOV.
     ⁶) Right shift when pressed with another key. medium long: to toggle _FUN. Long: toggle _RAR.

Remarks: The left modifiers have a slight delay in combination with an outside pointer device (mouse, stylus).
It seems this will be difficult to fix, because it is spread over two devices. To avoid the
±0.2 second delay, activate a layer where the modifiers are direct (`_PAD`, `_MOV`), using the layer toggle on
left shift. 

The two keys with ';' (Del;`_ACC`, Right;`_RAR`) do not auto-repeat on double tap, like QMK normal layer-tap keys.

There is an uncluttered _Delete_ on `_PAD`, an uncluttered _Right_ arrow on the `_MOV` layer.

There is an uncluttered _Tab_ on both the `_DRA` and `_ACC` layers. They can be modified with _Control_ there.

Holding both `_..._NSY` keys left and right of the "split space bar" (enter, space) results in layer `_DRA`.

Holding either one of the just above mentioned `_..._NSY` layer keys (<3 and 3>), with the `_ACC` layer key
(on <2) results in layer `_BON`.
