jeebak's layout

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.

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 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.

  ,-----------------------------------------------------------------------------------.
  |   0  |   1  |   2  |   3  |   4  |   5  |   6  |   7  |   8  |   9  |   0  | Bksp |

TouchCursor layer plus personal customizations

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. 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.

  ,-----------------------------------------------------------------------------------.
  |AltTab|CmdTab|CtlTab|  GUI |Shift |  ~   |Insert| Home |  Up  | End  | Bksp |      |
  |------+------+------+------+------+-------------+------+------+------+------+------|
  |      | Alt  |Space |      | Find |Again | PgUp | Left | Down |Right |      |      |
  |------+------+------+------+------+------|------+------+------+------+------+------|
  |      | Undo | Cut  | Copy |Paste |  `   | PgDn | Del  |      |      |      |      |
  |------+------+------+------+------+------+------+------+------+------+------+------|
  |      |      |      |      |      |             |      |      |      |      |      |

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.
