-# bcat's Corne layout
-
-This is my favorite split ergo layout for typing, featuring the traditional
-four ortho/ergo layers (Default, Lower, Raise, Adjust). It is loosely inspired
-by the default Planck (numbers on Lower, symbols on Raise) and Crkbd (Space on
-left, Enter on right) layouts, but has since been redesigned heavily according
-to the principles described below.
-
-* Since my most-frequently-used keyboard shortcuts involve Ctrl, which lives on
-the left half of the keyboard, keys frequently used with it (numbers, function
-keys, etc.) are on the Raise layer activated by the right thumb.
-
-* Navigation can be done on the right half alone, to enable simultaneous
-left-handed mousing. Additionally, Web pages can be scrolled with Space or
-Shift+Space on the left half alone, to enable taking notes with the right hand
-at the same time.
-
-* Other than Right Shift (which I seldom use), mods aren't rebound on layers.
-
-* Likewise, Backspace is not rebound on layers to avoid having to let go of
-layer-switch keys to correct mistakes.
-

-
-* The alpha keys are a standard QWERTY layout, no funny business there.
-
-* Tab and Backspace are in familiar locations from my row-staggered boards
-(almost all of which use HHKB-style split backspace).
-
-* The Esc key is next to the home row for convenience in Vim.
-
-* Likewise, the Ctrl key is in the same place as on my row-staggered boards
-(where I've been remapping Caps Lock as Ctrl since before even using QMK).
-
-* There are two Shift keys, although I generally use Left Shift. (I've
-considered replacing Right Shift with another key, but haven't chosen one.)
-
-* Lower and Raise layer-switch keys are in the resting position of my left and
-right thumbs, respectively.
-
-* Space and Enter are on the big thumb keys so they're easy to press.
-
-* Ctrl is on the left for ease of chording, especially one-handed use of common
-shortcuts like Ctrl+T and Ctrl+W. This puts Alt on the right by the process of
-elimination.
-
-## Lower layer

-
-* This could also be called the "symbol layer".
-
-* Shifted numbers are bound in their usual positions on the top row.
-
-* Hyphen/Underscore and Equals/Plus are in the right index- and middle-finger
-columns for easy reach. They share the same relative position as on a
-row-staggered keyboard, and the shifted versions are physically above the
-unshifted versions as a mnemonic device.
-
-* Brackets and braces are placed below the parens for easy recall. Once again,
-the shifted versions are on the home row and the unshifted versions are on the
-bottom row.
-
-* Forward Slash/Pipe and Backtick/Tilde fill out the remaining positions on the
-right half, with the same relative positions as on a row-staggered HHKB layout.
-And yup, the shifted versions are above the unshifted versions.
-
-* Remaining keys from a TKL are placed out of the way on the bottom row of the
-left half.
-
-* The home row on the left half contains handy shortcuts for zooming and browser
-navigation.
-
-* Lower+Esc is bound to Ctrl+Space because the Ctrl and Space keys are both on
-the left thumb, so this key combination (which I use for tmux prefix and editor
-autocomplete) is hard to press in its natural location.
-
-* Lower+Tab is bound to a custom Alt+Tab macro that keeps the Alt modifier held
-as long as the Lower key is held down. This means that window switching is on
-Lower+Tab immediately next to browser tab switching (Ctrl+Tab).
-
-## Raise layer

-
-* This could also be called the "number layer".
-
-* Unshifted numbers are bound in their usual positions on the top row.
-
-* Arrow keys are on VIM-style HJKL keys.
-
-* Home/End and Page Up/Page Down are in the same column as the arrow keys, but
-translated down one row. (This means that the comma and period keys are not
-bound on the number layer, which makes data entry a bit funky. I might add a
-dedicated numpad layer to compensate.)
-
-* Function keys F1–F10 take up most of remaining space on the left half, with
-F11 and F12 spilling over to the right half. (This puts the most used function
-keys (F1–F5) on the home row.)
-
-* Insert and Delete are on the rightmost column, because there didn't seem to
-be a better place to put them.
-
-* Caps Lock is bound in the same position as on an HHKB, for lack of an obvious
-better location.
-
-## Adjust layer

-
-* Media keys are centered around the ESDF cluster, just like I arrange them on
-row-staggered keyboards. (It's even more sensible with columnar stagger.)
-
-* The navigation keys are replaced by RGB controls. Again, this mirrors the
-positioning I use on my row-staggered keyboards.
-
-* Finally, reset keys live at the top-left corner of the right half where it's
-reasonably hard to press them by accident.
