# 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 most of the modifiers are on the left half, keys frequently pressed
|
||
together with mods (e.g., 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.
|
||
|
||
## Default layer
|
||
|
||
|
||
|
||
([KLE](http://www.keyboard-layout-editor.com/#/gists/08d9827d916662a9414f48805aa895a5))
|
||
|
||
* 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).
|
||
|
||
* 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, because I do use Right Shift on occasion (even
|
||
though I'm predominately a Left Shift-er).
|
||
|
||
* Lower and Raise layer-switch keys are below the left and right thumb,
|
||
respectively, when resting my fingers on the home row.
|
||
|
||
* Space and Enter are on the big thumb keys so they're easy to press.
|
||
|
||
* Alt is on the left so I can navigate back (Alt+Raise+H) and forward
|
||
(Alt+Raise+L) without having to uncomfortably hit two thumb keys on the same
|
||
half. This puts Super on the right by the process of elimination.
|
||
|
||
* Escape shares a mod-tap key with Ctrl, which is convenient for Vim, but not
|
||
something I'm totally in love with, as even after tweaking `TAPPING_TERM` I
|
||
still get occasional spurious Esc taps. (I might move Esc up a key and put Tab
|
||
on a layer, but that'd take some getting used to....)
|
||
|
||
## Lower layer
|
||
|
||
|
||
|
||
([KLE](http://www.keyboard-layout-editor.com/#/gists/c3fba5eaa2cd70fdfbdbc0f9e34d3bc0))
|
||
|
||
* 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.
|
||
|
||
* Caps Lock is bound in the same position as on an HHKB, for lack of an obvious
|
||
better location.
|
||
|
||
* Some extra keys are placed on the bottom row of the left half, ensuring every
|
||
key on a TKL has a binding.
|
||
|
||
* The left-half home row is reversed for future use. (It's free real estate.)
|
||
|
||
## Raise layer
|
||
|
||
|
||
|
||
([KLE](http://www.keyboard-layout-editor.com/#/gists/08b44355d4ca85d294bad9e2821f91d7))
|
||
|
||
* 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.
|
||
|
||
## Adjust layer
|
||
|
||
|
||
|
||
([KLE](http://www.keyboard-layout-editor.com/#/gists/77e7572e077b36a23eb2086017e16fee))
|
||
|
||
* 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.
