Qwerty/Dvorak/Colemak Layer

Basic keymap layer for each keyboard layout.

Pseudo US Layer

A layer that can be used with the same physical layout as the previously activated basic (Qwerty/Dvorak/Colemak) keymap layer, with the keyboard still configured as a Japanese keyboard on the OS.

This is useful when using virtual environments and remote desktops, because you can use Japanese Windows with the same keyboard without changing the OS keyboard settings. Also, when using the keyboard as a US keyboard on Windows OS, all keys existing only on Japanese keyboards are ignored and it is not possible to assign these keys to the desired function of any application. You can avoid such problems.

Tenkey/Mouse Layer

Tenkey (numeric keypad) and mouse layers. For the Tenkey to work, Numlock must be turned on in the OS.

HHKB Fn Layer

A layer that is equivalent to Fn key of Happy Hacking Keyboard. There are also some layer switching keys and special function keys.

SpaceFN Layer

Customized SpaceFN layer. There are left-hand and right-hand Arrows/Home/End/PageUp/PageDown keys. Frequently used keys in HHKB Fn layer are configured to this layer and can be used as an alternative layer to the HHKB Fn layer.

Special function keycodes

Pseudo US keycode

A special keycode that implements Pseudo US Layout.

Mac mode keycode

A special keycode that toggles Mac mode. When Mac mode is enabled, the keymap of the Left Inner/Outer and Right Inner/Outer keys are changed for macOS. See Left Inner/Outer, Right Inner/Outer keys for details.

Left Inner/Outer, Right Inner/Outer keycodes

If you tap a Mod-Tap key and another key within the time specified by TAPPING_TERM, QMK interprets these keys as if they were pressed at the same time even if they were not pressed simultaneously. Therefore, for fast typists, Mod-Tap can accidentally send a keycode with modifier. These special keycodes allow you to work around this issue and change the keymap in Mac mode.

These keys work as follows:

Mac mode: Disabled

Key	Keycode	Tap	Hold
Left Inner	L_INNER	KC_MHEN	KC_LALT
Left Outer	L_OUTER	KC_LGUI	KC_LGUI
Right Inner	R_INNER	KC_KANA	KC_RALT
Right Outer	R_OUTER	KC_RGUI	KC_RGUI

Mac mode: Enabled

Key	Keycode	Tap	Hold
Left Inner	L_INNER	KC_LANG2	KC_LCMD
Left Outer	L_OUTER	KC_LOPT	KC_LOPT
Right Inner	R_INNER	KC_LANG1	KC_RCMD
Right Outer	R_OUTER	KC_ROPT	KC_ROPT
