+# Sean Hunter's Planck Layout
+
+## Main layout
+
+Inspired by my old typematrix dvorak keyboard, with escape, tab, enter and
+backspace in the middle.  
+
+```
+ ,-----------------------------------------------------------------------------------.
+ |   "  |   ,  |   .  |   P  |   Y  |   /  |   =  |   F  |   G  |   C  |   R  |   L  |
+ |------+------+------+------+------+------+------+------+------+------+------+------|
+ |   A  |   O  |   E  |   U  |   I  | ESC  | BSPC |   D  |   H  |   T  |   N  |   S  |
+ |------+------+------+------+------+------+------+------+------+------+------+------|
+ |   ;  |   Q  |   J  |   K  |   X  | TAB  | ENT  |   B  |   M  |   W  |   V  |   Z  |
+ |------+------+------+------+------+------+------+------+------+------+------+------|
+ | Sft  | Ctl  | Alt  | Gui  |Lower |    Space    |Raise |   <  |   v  |   ^  |   >  |
+ `-----------------------------------------------------------------------------------'
+ ```
+
+## Lower
+
+With Lower, the numbers are on the home row.  Brackets and braces are down the
+centre of the keyboard when holding lower, and most other special characters,
+can be found on the row below home.  One row up are the main function keys.
+The arrow keys become `Home`, `End` and `Page Up` and `Page Down`.
+
+ ```
+ ,-----------------------------------------------------------------------------------.
+ | F1   |  F2  |  F3  |  F4  |  F5  |  {   |  }   |  F6  |  F7  |  F8  |  F9  | F10  | 
+ |------+------+------+------+------+-------------+------+------+------+------+------|
+ |  1   |   2  |   3  |   4  |   5  |  [   |  ]   |   6  |   7  |   8  |   9  |  0   |
+ |------+------+------+------+------+------|------+------+------+------+------+------|
+ |   ~  |   |  |   `  |   -  |   _  | INS  | DEL  |   (  |   )  |   +  |   =  |  \   |
+ |------+------+------+------+------+------+------+------+------+------+------+------|
+ | Sft  | Ctl  | Alt  | Gui  |Lower |             |Raise | Home | PgDn | PgUp | End  |
+ `-----------------------------------------------------------------------------------'
+```
+
+## Raise
+
+With Raise, the middle row functions as though we are holding shift and typing
+numbers.  This makes it a little easier than trying to hold lower and shift at
+the same time.  The row below home is a set of keys mapped from `Gui-1` to
+`Gui-0`.  I use these to change virtual desktops on [i3](https://i3wm.org/).  I
+also include 'right' versions of the modifier keys on here.
+
+
+ ```
+ ,-----------------------------------------------------------------------------------.
+ | F11  |  F12 |  F13 |  F14 |  F15 |      |      |  F16 |  F17 |  F18 |  F19 | F20  | 
+ |------+------+------+------+------+-------------+------+------+------+------+------|
+ |  !   |   @  |   #  |   $  |   %  |Sleep | Wake |   ^  |   &  |   *  |   (  |  )   |
+ |------+------+------+------+------+-------------+------+------+------+------+------|
+ | GUI1 | GUI2 | GUI3 | GUI4 | GUI5 |      |      | GUI6 | GUI7 | GUI8 | GUI9 |GUI10 |
+ |------+------+------+------+------+------+------+------+------+------+------+------|
+ | Sft  | Ctl  | Alt  | Gui  |Lower |             |Raise | Gui  | Alt  | Ctl  | Sft  |
+ `-----------------------------------------------------------------------------------'
+
+```
+
+## Adjust
+
+Raise and lower at the same time give an adjustment layer, which allows
+changing to the numpad and movement layer, and adjusting the backlights
+(assuming you have them - I don't yet).  I have also added various media keys
+and the all-important `Reset` key for programming the keyboard.  I've got the
+ability to swap `Alt` and `Gui` in hardware and three special keys set up for
+[hammerspoon]( http://www.hammerspoon.org/) on mac.  If I ever start using this
+keyboard seriously on mac again (I'm using it mainly on Windows and Linux atm)
+I'll write a special Mac mode and redo all my hammerspoon config to be more
+like i3 on Linux.
+
+```

+
+I have added a numpad, although this is a little annoying at the moment as you
+have to first press `NumLock` to use.  I guess I could make a macro so as soon as
+you go into numpad mode it turns `NumLock` on.

+I have added a movement layer but at present I seldom use it.

+
+## Software Dvorak mode
+
+I have implemented a version of the main, lower and raise maps that works if
+the computer itself is in dvorak mode at the os level.  This allows me to work
+well on my laptop when I have to take it with me (eg to go to a meeting) and
+don't want the keyboard with me.  I simply set it in dvorak mode in the os and
+then put the keyboard into this mode.
+
+## TODO
+
+1. Actually learn to use the media keys
