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.

Layout features

• Extensive use of Mod Tap, e.g.
  • Tap sends Esc, Hold sends Left Control
  • Tap sends Enter, Hold sends Right Shift
  • ... and many more
• 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)
• Centered symbol/bracket cluster on Lower/Raise
  • Inspired by hexwire layout
  • Programming-oriented
• Spacebar sends modifier keys on hold (this is finicky in practice. may shut off completely)
  • Control and Alt/Meta on left and right space, respectively
  • Strict space available on Function and Numpad layers
  • For Emacs keychords
• Extra dedicated layers
  • Numpad (available with tap toggle)
  • Function key (F01-24)
• Redunant keys where it is convenient to have characters together on one layer
