# 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.
## 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
