Jason Yamada-Hanff 153d1ecfcc Keymap: add jyh levinson keymaps (#4284) 
* Keymap: add jyh levinson keymaps

remove tap dance number keys due to sluggish responses

simplify I2C configuration

reverse hyper and meh positions

reduce tapping term to allow fast typing with mod tap space keys

remove Alt hold on right space key. too many false touches.

add vim-style arrows (hjkl) on asdf; semicolon/quote on raise

correct documentation string for jyh levinson layout

add alternative levinson layout for jyh

more inspiration from atreus keyboard. keeps shift in the expected
places. reduces number of layers. puts numpad layout easily
accessible. places important keys on palms and meta keys on top
corners for xmonad.

correct layer switching in jyh2 levinson layout

I was getting stuck on the numpad layer because the numpad hold key
was remapped once the layer was activated. Bad idea. Minor other
refinements.

use curly bracket { instead of brace [ on raise layer

add RGB keys on adjust layer

bootmagic key is confusing. turn it off.

try out permissive hold setting to make mod-tap better

remove hold for right control on quote key. too many mistakes

turn off permissive hold. it was causing unexpected behavior

enable rgb underglow animations

add make it pink/blue key to levinson layout

prevent stuck modifiers in jyh2 levinson keymap

* fix up deprecated code after code review

* remove PREVENT_STUCK_MODIFIERS because it is default

jyh's levinson layout

Levinson built on rev2 PCBs. A split 4x12 keyboard with LED backlights.

The layout is oriented towards needs for programming, Emacs, XMonad, and experience with 60% keyboards with no base layer arrow keys (Poker). It makes heavy use of modifiers and layers. It is influenced by good ideas from the Atreus keyboard layout.

Layout features

  • Extensive use of Mod Tap, e.g.
    • Tap sends Esc, Hold sends Left Control
    • Tap sends Tab, Hold activates Numpad layer
    • Tap sends - , Hold sends Shift
    • ... and many more
  • Places Tab and Enter on bottom corners, for hitting with palm
  • Meta is available on top corners, for controlling XMonad
  • Control on center key, for Emacs (among other things)
  • Backspace (Control Hold) and Space on center keys
  • All 60% keys available on base layer, except for numbers
  • Hyper and Meh keys
  • Right modifier keys in place of arrow keys
    • Arrows are instead available in two alternate locations:
    • WASD arrows on Adjust
    • Arrow cluster on Raise (inspired by hexwire)
  • Numpad and Numrow on Raise layer. Each is faster in some contexts
  • Function keys on Lower
  • Dynamic macros from QMK firmware on Adjust
  • Redunant keys where it is convenient to have characters together on one layer
