+ cbbrowne custom keyboard
+ ==============================
+
+ Due to cbbrowne@acm.org
+ Christopher Browne
+
+ This was originally based on the default keyboard map, but I have been
+ doing sundry experimentation:
+
+ 1. Experiments
+ ----------------------------------------
+
+ * To figure things out about the toolset
+ * I'm an Emacs guy, so will be needing a fair bit of tuning
+ * It made sense to mess around some with keyboard maps.
+ - I tried added Workman alongside Dvorak and Colemak
+ - Boy, oh boy, these don't help!!!
+ - I have done 30 years of learning of Emacs key mappings, and
+ these alternative keyboards massively mess me up
+ - I added a keypad, originally based on keymaps/numpad.c, but
+ mighty substantially revised, as that one seems to be rotated 90
+ degrees from usual conventions for number pads
+ * The keypad layer also includes some sample "hacks" of cool things,
+ all using actions attached in using the function action_get_macro()
+ - Key [1][2] aka "q" types out my name, cbbrowne, as a fun example
+ of a key generating a bunch of keystrokes. The keystroke is
+ sufficiently inconvenient that it isn't terribly practical for me
+ to use it, but hey, it shows how others might use this facility
+ in a more useful context.
+ - Key [2][2] aka "a" uses a random number generator to select a digit 0-9 at random
+ - Key [3][2] aka "z" uses a random number generator to select a letter a-z at random
+ - Key [1][3] aka "e" spits out the keymap version number
+
+ 2. Some code structure ideas
+ ---------------------------------------------------
+
+ Each layer is given a name to aid in readability, which is then
+ used in the keymap matrix below. The underscores do not denote
+ anything - you can have a layer called STUFF or any other name.
+
+ Layer names don't all need to be of the same length, obviously, and
+ you could also skip them entirely and just use numbers, though that
+ means needing to manage the numbers.
+
+ It is preferable to keep the symbols short so that a line worth of
+ key mappings fits compactly onto a line of code. It might be an
+ interesting idea to express the maps rotated 90%, so that you
+ only need to fit 4 symbols onto each line, rather than 12.
+
+ I used enums to manage layer IDs and macro IDs so that I don't need
+ to care (beyond "start at 0", and arguably that's not needed) about
+ their values.
+
+ 3. Things I did not like about the default mapping
+ ---------------------------------------------------------
+
+ * I found control too hard to get to. I use it more than Tab, so
+ switched it there.
+ * Having dash on [lower-j] is a bit nonintuitive, but may be OK
+ * I switched ESC/TAB/M(0) around
+ * I'm suspicious that I want to shift M(0) from [4][1] to [4][2],
+ and shift ESC off the first column so KC_LCTL and KC_LALT can
+ be on the first column.
+ * I needed to swap ' and ENTER
++
++4. TODO
++---------------------------------------------------------
++
++ * I use tmux quite a lot; the mollat keymap seems to have some
++ interesting helpers. It might be interesting to add a "tmux
++ layer"
++ * The mollat tmux layer also suggests some thoughts about Emacs
++ helpers.
++ * I do not presently have anything that handles X11 screen
++ switching, as with Control-Alt-various
++
