=======================
|
|
|
|
|
This WIP keymap attempts to minimize fingers straying away from the home row.
|
|
|
|
|
To aid in this endeavor, when additional modifyer keys to switch layers are
|
|
|
|
|
needed, they will be mapped to home row keys. The `keymap.c` file will contain
|
|
|
|
|
the exact changes. The diagrams in this README shows the highlights of the
|
|
|
|
|
changes from the default mappings.
|
|
|
|
|
|
|
|
|
|
I also decided to change all calls to `persistant_default_layer_set()` to
|
|
|
|
|
`default_layer_set()` since this is my personal perference.

## Macros
|
|
|
|
|
```
|
|
|
|
|
#define ALT_TAB M(KC_ALT_TAB)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Base Layers (Qwerty/Colemak/Dvorak)
|
|
|
|
|
These base layers are mostly the same as the default mappings. The interesting
|
|
|
|
|
changes are shown below. The `Ctrl/Esc`, mapped using `CTL_T(KC_ESC)` will emit
|
|
|
|
|
an `Escape` when tapped, and act as a `Control` key when held. A `TODO` item is
|
|
|
|
|
to see if it can also act as a `CapsLock` when double-tapped. The right shift
|
|
|
|
|
key acts as `Enter` when tapped, and as a `Shift` key when held. The arrow
|
|
|
|
|
keys, which have been moved to the
|
|
|
|
|
[TouchCursor](http://martin-stone.github.io/touchcursor/) layer, have been
|
|
|
|
|
replaced with the Media keys as shown. The `ML/A` key activates the Mouse layer
|
|
|
|
|
when held, and emits an `A` when tapped.
|
|
|
|
|
```

## Lower Layer (Symbols and Function Keys)
|
|
|
|
|
The symbols and functions keys are essentially the same as the default mapping.
|
|
|
|
|
The most notable changes are that the symbol keys from the `RAISE` layer have
|
|
|
|
|
been moved here. The remaining Media keys replace those that are now on the
|
|
|
|
|
base layers. The `BACKLIT` key has also been moved here.

## Raise Layer (Numbers and Arithmetic Operators)
|
|
|
|
|
All of the numbers and arithmetic operators are available on this layer. Some
|
|
|
|
|
keys are duplicated for the convenience of their positions. The `0` and `$`
|
|
|
|
|
keys at the far left are for quick access to beginning and end of line in vim.

|

## TouchCursor layer plus personal customizations
|
|
|
|
|
[TouchCursor](http://martin-stone.github.io/touchcursor/) uses the `Space` key
|
|
|
|
|
as the modifier, with the `IJKL` home row keys representing the inverted-T of
|
|
|
|
|
the arrow keys. All of the default TouchCursor keymappings for the right hand
|
|
|
|
|
are represented below. My personalizations include all of the keys shown for
|
|
|
|
|
the left hand. Having the `Alt` and `Shift` keys (as well as the `Control` key
|
|
|
|
|
from the base layers) readily accessible from the home row allows quick word
|
|
|
|
|
jumps and highlighting when used in conjunction with the arrow keys. The
|
|
|
|
|
`AltTab` macro is not only useful under Windows, but also under Mac when used
|
|
|
|
|
with alternative switchers like [HyperSwitch](https://bahoom.com/hyperswitch).
|
|
|
|
|
The `CmdTab` and `CtlTab` sequences are duplicated for easy access while in
|
|
|
|
|
this layer. The `KC_UNDO, KC_CUT, KC_COPY, KC_PASTE, KC_FIND,` and `KC_AGAIN`
|
|
|
|
|
keycodes have been mapped but they don't seem to work on Mac. Presumably
|
|
|
|
|
they'll work under Windows.
|
|
|
|
|
```

```
|
|
|
|

|
|
|
|
|
## Mouse Layer
|
|
|
|
|
The Mouse layer, closely mimics the layout/behaviour of the TouchCursor layer.
|
|
|
|
|
The `A` key is used to activate this layer. All 16 keycodes for the mouse from
|
|
|
|
|
the `doc/keycode.txt` file are represented, and logically located, IMHO. The
|
|
|
|
|
left and right click buttons are duplicated; on the right hand side, for a
|
|
|
|
|
quick click here and there, and again on the left hand side for when the
|
|
|
|
|
buttons need to be held for dragging things or highlighting text, thus allowing
|
|
|
|
|
the right hand to be free to use the up/down/left/right actions.
|
|
|
|
|
