+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
+`update_tri_layer()` 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](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 readily accessible from the
+home row allows quick word jumps and highlighting when used in conjunction with
+the arrow keys. 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.
