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
