# jyh's levinson layout
|
||
|
|
|

|
|
[Levinson](https://keeb.io/products/levinson-lets-split-w-led-backlight)
|
||
|
|
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
