This defines a firmware layout optimised for class 4j OS keymaps, which have square and curly brackets on both the second row and home row, and which have the extra keys Ro and Yen.
It is strongly recommended to use modifiers-japan.h in combination with this
layout.
In clockwise order from the bottom left, the orphan keys are mapped according to each of the class 4j keymaps:
| Keymap | L(Z) | L(A) | L(Q) | R(5) | L(6) | R(P) | R(;) | R(/) |
|---|---|---|---|---|---|---|---|---|
| ja_JP | ¥| | ]}(Mu) | [{(°) | -=(Ha) | ^~(He) | @`(") | :*(Ke) | _(Ro) |
The orphan keys are found in these physical locations on the Model01:
| LH column 0 | ... | LH column 6 | RH column 7 | ... | RH column 15 |
|---|---|---|---|---|---|
| PROG | ... | RIGHT_OF_5 | LEFT_OF_6 | ... | NUM |
| LEFT_OF_Q | ... | ... | ... | ... | RIGHT_OF_P |
| LEFT_OF_A | ... | ... | ... | ... | RIGHT_OF_SEMICOLON |
| LEFT_OF_Z | ... | ... | ... | ... | RIGHT_OF_SLASH |
RIGHT_OF_5 and LEFT_OF_6 are labelled LED and ANY on the
default keycap set.
Note that these labels refer to the relative positions of the keys in a US-QWERTY layout, but otherwise have no significance. These key labels always refer to the same physical keys on the Model01, no matter which language keymap is in use.
