Overview
|
|
========
|
|
|
|
Warning: dvorak touch typist, that uses qwerty and bepo locales on my
|
|
computer. 40+ years of vi, 30 years of vi in Emacs.
|
|
|
|
Recent years I have gone minimal, I don't use most of the keys on my ergodox,
|
|
or original edition dactyl. These maps work great on large and small keyboards,
|
|
my preference seems to be 40% split ergo keyboards like the corne.
|
|
|
|
I think that what is special here is the layouts. I don't worry too
|
|
much about leds, or RGB, although I do like oled. But really its mod_layer.h,
|
|
all the simple layer chunks and definitions, and the ability to apply that
|
|
to any keyboard with minimal effort. The other thing is the example it
|
|
provides for defining keymaps based on different OS locales. I use both
|
|
dvorak on Qwerty, and bepo/dvorak on bepo. That means I must change my
|
|
locale on my OS to match my keyboard which can do qwerty or bepo locales.
|
|
|
|
It is possible, as I do, to send a keycode invoking xmonad, to execute my
|
|
qwerty - bepo switch on my computer.
|
|
|
|
Besides using dvorak, another thing that colors my keyboard code is that I
|
|
have used the kinesis
|
|
advantage for for more than 2 decades. I have used the ergodox ez for several years
|
|
as well, so the evolution of my keymaps starts there with space, enter, backspace
|
|
and delete keys on the thumbs.
|
|
|
|
Layouts
|
|
-----------
|
|
This evolved from the old layout...wrapper code. Calling everything a wrapper seems
|
|
silly. So I took a step back.
|
|
|
|
Also, with all these layers it was a real pain to apply mods consistently and
|
|
easily. So I changed the way I use keymap macro wrappers and added in my own
|
|
mod layer. The only thing it has is the mods to apply. No more editing keymaps
|
|
to apply mods. I do it once, and it works everywhere I want.
|
|
|
|
All layouts, almost, boil down to a 3x5 x 2 matrix. Bepo is 3x6. Mostly, I want
|
|
my controls to stay the same. As we have been conditioned, these are the keys on
|
|
the edges, or middle. Not that they can't change but I don't usually change them
|
|
much, except the side edges, - the extra pinky columns.
|
|
the F keys, the columns to the left and right and the row on the bottom.
|
|
Thumb keys if you have them. Even the number row is practically the same.
|
|
|
|
With that in mind, reducing my layouts to 3x10 or 12 matrices would be great.
|
|
At the same time extracting my mods so they are easy to apply to any matrix.
|
|
So that's what is here.
|
|
|
|
At the bottom is the LAYOUT, needed by the keeb you have. Then I have my Layouts
|
|
to feed it with my ROWS macros which are my MOD layer. At the end of it all,
|
|
I give a 3x10 or 12 to a layout and I have a complete keyboard definition.
|
|
Creating a new keyboard map is super simple.
|
|
|
|
* mod_layer.h is the place for home row mods or any other mods.
|
|
* layouts.h is where I define a new matrix using the ROW macros when I need one.
|
|
* core_keys.h - where I define my custom keys. Ya know, the big enum.
|
|
* altlocal_keys.c - Alternate key/shift keys for emulation on other locales.
|
|
* core_keysets.h - Base layers; qwerty, dvorak, beakl, colemak, norman, carplax...
|
|
* edge_keys.h - defines the edges and bottom/thumb keys of a keyboard.
|
|
* layers.h - defines actual layers for navigation, symbols, keypad, layers, top rows, etc.
|
|
|
|
Process_records.c
|
|
--------------------
|
|
This is where the keycodes are processed...
|
|
|
|
Custom keys
|
|
-------------------
|
|
I have a lot of custom keys because of bepo. It is somewhat confusing this interaction
|
|
between a keyboard and the software that receives it.
|
|
|
|
A lot of my pain is invoked by my desire to have dvorak on bepo. Which works just fine,
|
|
although an english/cyrillic situation may not work so well. Currently I have
|
|
dvorak and beakl on bepo in addition to bepo it's self.
|
|
|
|
Alternate keycodes for emulating a layout on another locale/language.
|
|
-----------------------------
|
|
Because of wanting dvorak and beakl on bepo there was the necessity to create keys
|
|
from keycodes which were not combined. For this I have a special function that
|
|
takes a keycode and gives a proper shifted character for it. It is only a 2 keycode
|
|
definition, but it does the basic non-shifted and shifted characters as you define them.
|
|
|
|
Combos/Chords
|
|
----------------------------
|
|
This is recently new to me. I'm using them on my thumb keys which are all LT's.
|
|
the combos allow for layer locking for the Nav layer, and a oneshot for symbols
|
|
among other things.
|
|
|
|
I followed the simple example at the end of the doc than uses the
|
|
combos.def file to define the combos.
|
|
|
|
Tap-mods
|
|
-------------------------------------
|
|
I had been using MT on my thumbs for GUI,CTRL,ALT on hold along with
|
|
Escape, Enter, space and backspace, my thumb keys. I then added shift to my home row pinky key.
|
|
I had layer shifts to symbols, numbers, navigation all on the home row of both hands.
|
|
It worked nicely but choppy I think, switching hands for the holder of the layer is
|
|
a little like having no caps lock. It was a lot of work adding them to all my maps.
|
|
This is what prompted my mod_layer. So much easier. No maps to modify.
|
|
|
|
Then I moved to all home row mods with layers on my thumb keys.
|
|
|
|
This does allow for more rolls, and I have found chord/rolls simply from having my
|
|
xmonad controls be GUI-some-home-row-key-or-close. When Gui is your index finger,
|
|
everything gets easier.
|
|
|
|
Somewhere along the way I got a corne, and everything had to be small. and I realized
|
|
that everything really was small. My layers are blending back, with LTs near the
|
|
home row, and all the thumbs. On my dactyl I currently have 8 thumb keys per thumb,
|
|
I don't know what to do with them all. Remembering a time I thought that would be
|
|
awesome.
|
|
|
|
### tap_taplong and open_openclose
|
|
In process_records.c I have a nice couple of functions,
|
|
tap_taplong(), and open_openclose() for my non MT/LT functionality.
|
|
|
|
* I have home row mods for Shift, Ctrl, Alt, and Gui on both hands.
|
|
* I have a number of LT mods to raise layers nearby. Nav, toprows, symbol, keypad
|
|
are on both hands on the first and third rows around home row.
|
|
* Xmonad tap_taplong to pull up desktops or terminals with tap or hold.
|
|
* C-c/C-v, C-t/C-n, C-w/C-q are all on my Navigation layer as custom keys with tap_taplong.
|
|
* My thumbs are Enter/space and Esc/backspace which are also Navigation and toprows and symbol layers. They used to be GUI,CTRL,ALT,SFT. but all that's on the home row now.
|
|
* All of the paired characters on my symbol layer have a hold which closes them, and moves the cursor back between.
|
|
|
|
### caps word
|
|
Holding both pinkies on home row for double tapping term, is effectively
|
|
right-shift and left-shift, invokes caps-word. The next word will be capitalized.
|
|
It continues until it shouldn't.
|
|
|
|
BEPO vs Qwerty Locale/language/Layers
|
|
---------------------
|
|
Essentially they are different keycode sets. So anything that needs them, causes a layer.
|
|
So there are two symbol layers, two toprows layers, two keypad layers.
|
|
One for Qwerty and one for bepo. The Navigation layer is not affected.
|
|
|
|
I only have bepo, dvorak and beakl on bepo. There are a bunch for Qwerty.
|
|
I have a ton of basic layers. I'm most interested in beakl at the moment, but I've used Dvorak for more than 20 years. There is also qwerty, colemak, norman, carplax, etc.
|
|
|
|
The navigation/mouse layer is not affected by bepo/qwerty, but symbols and numbers are.
|
|
There are bepo versions of everything that needs it.
|
|
|
|
Navigation Layer
|
|
-----------------------
|
|
I do not use a mouse. I use Xmonad as my window manager, and I have
|
|
practically no use for one. They are necessary however. So I have
|
|
a Navigation layer which is all mouse, arrows, home, end, tab, page
|
|
up, down, 5 mouse buttons and so on.
|
|
This layer is not affected by bepo/qwerty, but symbols and numbers are.
|
|
There are bepo versions of everything that needs it.
|
|
|
|
Arrow combos work just fine, in emacs I use SFT(arrows) to move between windows.
|
|
To do this; shift is my left pinky home, Nav is right thumb Enter, and one of the four
|
|
home keys of my left hand are the arrows. Home row mods allow this to work well.
|
|
|
|
I don't use the arrows on the dactyl and kinesis, even though they are there.
|
|
|
|
Symbol Layer
|
|
-------------------
|
|
The symbol layer is based on the Beakl15 symbol layer.
|
|
The beakl symbol layer is intuitive and fairly easy to remember. There are 3 versions.
|
|
The original, an extended called A, and an extended and enhanced for vi, called B.
|
|
The primary purpose of the extension was to provide keys which might not be available
|
|
elsewhere on the default layer. B, takes this further and moves :/? to better places.
|
|
|
|
TopRows Layer
|
|
--------------------
|
|
I think, truly this is the layer that makes tiny keyboards accessible in the beginning.
|
|
This is basically the number row, the shifted number row and the function key row.
|
|
I have them so it is numbers on the home row, shifted keys above and functions below.
|
|
There are multiple choices, I currently use the beakl number row, with everything
|
|
else as you would expect.
|
|
|
|
Keypad Layer
|
|
--------------
|
|
There are several variations of keypads and function key pads in various sizes.
|
|
Currently I am using a Beakl Keypad on the left hand and 3x4 funcpad on the right.
|
|
|
|
OLED
|
|
--------------------
|
|
It shows the basic stuff I could find in most places. The
|
|
default layer, the current layer, the mods, the locks, the last key pressed, and
|
|
a map of the current layer as simply as possible. I'm sure there is more that could
|
|
be done. @Drashna has some fancy stuff. If the display is big enough, there is even
|
|
a display of the current layer's keymap.
|
|
|
|
XMonad
|
|
---------------------
|
|
I use xmonad. Gui is my hot key for that. With home row mods I have home
|
|
row chords which give me access to my desktops, my scratchpads/terminals,
|
|
custom key KC_XM_PORD, among others. It sometimes feels that I am playing
|
|
an instrument when I invoke xmonad to do something.
|
|
|
|
I had an xmonad layer at one time, it was basically dvorak, I would invoke it
|
|
with a GUI mod, so that even on bepo, or colemak, my xmonad commands remain the same.
|
|
|
|
I'm going to need to revisit that, as things are, all the commands move when I change
|
|
to a different default layer from dvorak.
|
|
|
|
Combo's can alleviate some of this pain. More to play with.
|
|
|
|
|
|
Tap Dance
|
|
--------------------
|
|
I have a lot of tap dance, It's turned off. It's big. tap-hold works pretty well most of the time, instead.
|
|
My favorites were tab-backtab, home-end.
|
|
|
|
Switching the OS keyboard
|
|
-------------------------
|
|
This varies from system to system. I use Arch Linux, so I use ```setxkbmap```.
|
|
I've included a helper script which makes it easy to switch between EN and FR Bepo,
|
|
called switch-kbd. In xmonad I invoke this with a keystroke. so, same deal. just map
|
|
the keystroke to a key.
