+# QMK Breaking Change - 2020 May 30 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+The list of changes follows.
+
+
+## Core Changes
+
+### Converting V-USB usbdrv to a submodule
+
+[#8321](https://github.com/qmk/qmk_firmware/pull/8321) and [qmk_compiler#62](https://github.com/qmk/qmk_compiler/pull/62).
+
+These PRs move the V-USB driver code out of the qmk_firmware repository and into a submodule pointed at https://github.com/obdev/v-usb. This will make it easier to update the codebase if needed, while applying any potential QMK-specific modifications by forking it to the QMK GitHub organization.
+
+### Unify Tap Hold functions and documentation
+
+[#8348](https://github.com/qmk/qmk_firmware/pull/8348)
+
+Updates all of the per key tap-hold functions to pass the `keyrecord_t` structure, and include documentation changes.
+
+Any remaining versions or code outside of the main repo will need to be converted: 
+| Old function                                         | New Function                                                              |
+|------------------------------------------------------|---------------------------------------------------------------------------|
+|`uint16_t get_tapping_term(uint16_t keycode)`         |`uint16_t get_tapping_term(uint16_t keycode, keyrecord_t *record)`         |
+|`bool get_ignore_mod_tap_interrupt(uint16_t keycode)` |`bool get_ignore_mod_tap_interrupt(uint16_t keycode, keyrecord_t *record)` |
+
+### Python Required In The Build Process
+
+[#9000](https://github.com/qmk/qmk_firmware/pull/9000)
+
+This is the last release of QMK that will work without having Python 3.6 (or later) installed. If your environment is not fully setup you will get a warning instructing you to set it up.
+
+After the next breaking change you will not be able to build if `bin/qmk hello` does not work.
+
+### Upgrade from tinyprintf to mpaland/printf
+
+[#8269](https://github.com/qmk/qmk_firmware/pull/8269)
+
+- Provides debug functionality on ChibiOS/ARM that is more compliant than previous integrations.
+- Less maintenence, fewer QMK customisations, and allows QMK to sidestep previous compile and runtime issues.
+- A `make git-submodule` may be required after pulling the latest QMK Firmware code to update to the new dependency.
+
+### Fixed RGB_DISABLE_AFTER_TIMEOUT to be seconds based & small internals cleanup
+
+[#6480](https://github.com/qmk/qmk_firmware/pull/6480)
+
+- Changes `RGB_DISABLE_AFTER_TIMEOUT` to be based on milliseconds instead of ticks.
+- Includes a code cleanup, resulting in a savings of 100 bytes, depending on features used.
+- Fixed issues with timeouts / suspending at the wrong time not turning off all LEDs in some cases.
+
+The `RGB_DISABLE_AFTER_TIMEOUT` definition is now deprecated, and has been superseded by `RGB_DISABLE_TIMEOUT`. To use the new definition, rename `RGB_DISABLE_AFTER_TIMEOUT` to `RGB_DISABLE_TIMEOUT` in your `config.h` file, and multiply the value set by 1200.
+
+Before: `#define RGB_DISABLE_AFTER_TIMEOUT 100`  
+After: `#define RGB_DISABLE_TIMEOUT 120000`
+
+### Switch to qmk forks for everything
+
+[#9019](https://github.com/qmk/qmk_firmware/pull/9019)
+
+Fork all QMK submodules to protect against upstream repositories disappearing.
+
+### code cleanup regarding deprecated macro PLAY_NOTE_ARRAY by replacing it with PLAY_SONG
+
+[#8484](https://github.com/qmk/qmk_firmware/pull/8484)
+
+Removes the deprecated `PLAY_NOTE_ARRAY` macro. References to it are replaced with `PLAY_SONG`, which references the same function.
+
+### fixing wrong configuration of AUDIO feature
+
+[#8903](https://github.com/qmk/qmk_firmware/pull/8903) and [#8974](https://github.com/qmk/qmk_firmware/pull/8974)
+
+`audio_avr.c` does not default to any pin; there has to be a #define XX_AUDIO in config.h at some level for Audio to actually work. Otherwise, the Audio code ends up cluttering the firmware, possibly breaking builds because the maximum allowed firmware size is exceeded.
+
+These changes fix this by disabling Audio on keyboards that have the feature misconfigured, and therefore non-functional.
+
+Also, add a compile-time error to alert the user to a missing pin-configuration (on AVR boards) when `AUDIO_ENABLE = yes` is set.
+
+
+## Keyboard Refactors
+
+### Migrating Lily58 to use split_common
+
+[#6260](https://github.com/qmk/qmk_firmware/pull/6260)
+
+Modifies the default firmware for Lily58 to use the `split_common` library, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+- Serial Communication
+
+This allows current lily58 firmware to advance with updates to the `split_common` library, which is shared with many other split keyboards.
+
+#### To migrate existing Lily58 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-445ac369c8717dcd6fc6fc3630836fc1):
+- Remove `#define SSD1306OLED` from config.h
+
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- Alternatively, if you did not change the OLED code from that in `default`, you may find it easier to simply copy the [relevant section](https://github.com/qmk/qmk_firmware/blob/4ac310668501ae6786c711ecc8f01f62ddaa1c0b/keyboards/lily58/keymaps/default/keymap.c#L138-L172). Otherwise, the changes you need to make are as follows (sample change [here](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7R138-R173))
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L138-L141) the block
+```c
+#ifdef SSD1306OLED	
+  iota_gfx_init(!has_usb());   // turns on the display	
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the functions `matrix_scan_user`, `matrix_update` and `iota_gfx_task_user`
+- Find/Replace `matrix_render_user(struct CharacterMatrix *matrix)` with `iota_gfx_task_user(void)`

+### Refactor of TKC1800 to use common OLED code
+
+[#8472](https://github.com/qmk/qmk_firmware/pull/8472)
+
+Modifies the default firmware for TKC1800 to use the in-built I2C and OLED drivers, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+
+This allows current TKC1800 firmware to advance with updates to those drivers, which are shared with other keyboards.
+
+#### To migrate existing TKC1800 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-d10b26e676b4a55cbb00d71955116526):
+- Remove `#define SSD1306OLED` from config.h
+
+[Changes to `tkc1800.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-3b35bd30abe89c8110717c6972cd2cc5):
+- Add the following to avoid debug errors on HID_listen if the screen is not present
+```c
+void keyboard_pre_init_kb(void) {
+  setPinInputHigh(D0);
+  setPinInputHigh(D1);
+
+  keyboard_pre_init_user();
+}
+```
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-05a2a344ce27e4d045fe68520ccd4771):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L91-L158) the block
+```c
+#ifdef SSD1306OLED	
+  iota_gfx_init(!has_usb());   // turns on the display	
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the function `iota_gfx_task_user`
+
+### Split HHKB to ANSI and JP layouts and Add VIA support for each
+
+[#8582](https://github.com/qmk/qmk_firmware/pull/8582)
+
+- Splits the HHKB codebase into two separate folders `keyboards/hhkb/ansi` and `keyboards/hhkb/jp`.
+- Adds VIA Configurator support for both versions.
+
+#### Migrating existing HHKB keymaps
+
+- Remove any checks for the `HHKB_JP` definition
+  - All checks for this definition have been removed, and each version uses the source that is appropriate to that version.
+- Move the directory for your keymap into the appropriate `keymaps` directory
+  - `keyboards/hhkb/ansi/keymaps/` for ANSI HHKBs
+  - `keyboards/hhkb/jp/keymaps/` for HHKB JPs
+- Compile with the new keyboard names
+  - This PR changes the compilation instructions for the HHKB Alternate Controller. To compile firmware for this controller moving forward, use:
+    - `make hhkb/ansi` for ANSI-layout HHKBs
+    - `make hhkb/jp` for HHKB JP keyboards

 The QMK CLI operates using the subcommand pattern made famous by git. The main `qmk` script is simply there to setup the environment and pick the correct entrypoint to run. Each subcommand is a self-contained module with an entrypoint (decorated by `@cli.subcommand()`) that performs some action and returns a shell returncode, or None.
 
+## Developer mode:
+
+If you intend to maintain keyboards and/or contribute to QMK, you can enable the CLI's "Developer" mode:

-
-By default, the tapping term and related options (such as `IGNORE_MOD_TAP_INTERRUPT`) are defined globally, and are not configurable by key.  For most users, this is perfectly fine.  But in some cases, dual function keys would be greatly improved by different timeout behaviors than `LT` keys, or because some keys may be easier to hold than others.  Instead of using custom key codes for each, this allows for per key configurable timeout behaviors.
-
-There are two configurable options to control per-key timeout behaviors:
-
-- `TAPPING_TERM_PER_KEY`
-- `IGNORE_MOD_TAP_INTERRUPT_PER_KEY`

 Many keyboards support backlit keys by way of individual LEDs placed through or underneath the keyswitches. This feature is distinct from both the [RGB underglow](feature_rgblight.md) and [RGB matrix](feature_rgb_matrix.md) features as it usually allows for only a single colour per switch, though you can obviously install multiple different single coloured LEDs on a keyboard.

 Sometimes, however, a P-channel MOSFET, or a PNP transistor is used. In this case, when the transistor is on, the pin is driven *low* instead.
 
 This functionality is configured at the keyboard level with the `BACKLIGHT_ON_STATE` define.

+A pulldown resistor is also placed between the gate pin and ground to keep it at a defined state when it is not otherwise being driven by the MCU.
+The values of these resistors are not critical - see [this Electronics StackExchange question](https://electronics.stackexchange.com/q/68748) for more information.

Specifically, dual function keys like `LT` and `MT` use a 16 bit keycode. 4 bits are used for the function identifier, the next 12 are divided into the parameters. Layer Tap uses 4 bits for the layer (and is why it's limited to layers 0-16, actually), while Mod Tap does the same, 4 bits for the identifier, 4 bits for which mods are used, and all of them use 8 bits for the keycode. Because of this, the keycode used is limited to `0xFF` (0-255), which are the basic keycodes only.

+# Raw HID
+
+Raw HID allows for bidirectional communication between QMK and the host computer over an HID interface. This has many potential use cases, such as switching keymaps on the fly or changing RGB LED colors and modes.
+
+There are two main components to getting raw HID working with your keyboard.
+
+## Keyboard firmware
+
+The implementation is fairly straightforward for the firmware.
+In your `rules.mk` add:
+
+```make
+RAW_ENABLE = yes
+```
+
+In your `keymap.c` include `"raw_hid.h"` and implement the following:
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    // Your code goes here. data is the packet received from host.
+}
+```
+
+The `"raw_hid.h"` header also declares `void raw_hid_send(uint8_t *data, uint8_t length);` which allows sending packets from keyboard to host. As an example, it can also be used for debugging when building your host application by returning all data back to the host.
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    raw_hid_send(data, length);
+}
+```
+
+`raw_hid_receive` can receive variable size packets from host with maximum length `RAW_EPSIZE`. `raw_hid_send` on the other hand can send packets to host of exactly `RAW_EPSIZE` length, therefore it should be used with data of length `RAW_EPSIZE`.
+
+Make sure to flash raw enabled firmware before proceeding with working on the host side.
+
+## Host (Windows/macOS/Linux)
+
+This is the more complicated part as it will require some digging.
+
+To connect your host computer to your keyboard with raw HID you need four pieces of information about your keyboard:
+
+1. Vendor ID
+2. Product ID
+3. Usage Page
+4. Usage
+
+The first two can easily be found in your keyboard's `config.h` in the keyboard's main directory under `VENDOR_ID` and `PRODUCT_ID`.
+
+The final two can be overridden in your keyboard's `config.h` in the keyboard's main directory by redefining the values: `#define RAW_USAGE_PAGE 0xFF60` and `#define RAW_USAGE_ID 0x61`.
+
+By default, **Usage Page** is `0xFF60` and **Usage** is `0x61`.
+
+### Building your host
+
+You can build your host using any language that has an available HID implementation library if you don't wish to make your own. The ones we know of for popular languages are:
+
+* Node: [node-hid](https://github.com/node-hid/node-hid).
+* C: [hidapi](https://github.com/libusb/hidapi).
+* Java: [purejavahidapi](https://github.com/nyholku/purejavahidapi) and [hid4java](https://github.com/gary-rowe/hid4java).
+* Python: [pyhidapi](https://pypi.org/project/hid/).
+
+This is not an exhaustive cross-platform list but should get you started. There are no special requirements for using raw HID so any HID library should work.
+
+Now that you have all four pieces of information required to open HID interface to your keyboard. All you need to do is use your library's available functions to open the device with its ID parameters.
+
+Note that Vendor ID and Product ID are not actually required to open the device. They are used only to filter to a specific device out of the many HID devices you have plugged in. Many libraries will give you the option to open the device using Product Name or Manufacturer Name instead, `node-hid` being a prime example. This will create issues for devices with builtin USB Hub or any extra HID interfaces where you will have multiple interfaces with the same name or from the same manufacturer. The Vendor ID together with Product ID create a unique designation to a single interface and will not exhibit this problem. Therefore, even if your library doesn't require you to, it is best to use them to avoid issues.
+Unlike Vendor ID and Product ID though, Usage Page and Usage are necessary for successful communication.
+
+It should go without saying that regardless of the library you're using, you should always make sure to close the interface when finished. Depending on the operating system and your particular environment there may be issues connecting to it again afterwards with another client or another instance of the same client if it's not explicitly closed.

 it easy to use your underglow LEDs as status indicators to show which keyboard layer is currently active, or the state of caps lock, all without disrupting any animations. [Here's a video](https://youtu.be/uLGE1epbmdY) showing an example of what you can do.

Also, increasing the maximum will increase the firmware size, and will slow sync on split keyboards.

 # Tap Dance: A Single Key Can Do 3, 5, or 100 Different Things
 
-## Introduction
+## Introduction :id=introduction
+
 Hit the semicolon key once, send a semicolon. Hit it twice, rapidly -- send a colon. Hit it three times, and your keyboard's LEDs do a wild dance. That's just one example of what Tap Dance can do. It's one of the nicest community-contributed features in the firmware, conceived and created by [algernon](https://github.com/algernon) in [#451](https://github.com/qmk/qmk_firmware/pull/451). Here's how algernon describes the feature:
 
 With this feature one can specify keys that behave differently, based on the amount of times they have been tapped, and when interrupted, they get handled before the interrupter.
 
-## Explanatory Comparison with `ACTION_FUNCTION_TAP`
-`ACTION_FUNCTION_TAP` can offer similar functionality to Tap Dance, but it's worth noting some important differences. To do this, let's explore a certain setup! We want one key to send `Space` on single-tap, but `Enter` on double-tap.
+## How to Use Tap Dance :id=how-to-use
 
-With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and has the problem that when the sequence is interrupted, the interrupting key will be sent first. Thus, `SPC a` will result in `a SPC` being sent, if `SPC` and `a` are both typed within `TAPPING_TERM`. With the Tap Dance feature, that'll come out correctly as `SPC a` (even if both `SPC` and `a` are typed within the `TAPPING_TERM`.
-
-To achieve this correct handling of interrupts, the implementation of Tap Dance hooks into two parts of the system: `process_record_quantum()`, and the matrix scan. These two parts are explained below, but for now the point to note is that we need the latter to be able to time out a tap sequence even when a key is not being pressed. That way, `SPC` alone will time out and register after `TAPPING_TERM` time.
-
-## How to Use Tap Dance
-But enough of the generalities; lets look at how to actually use Tap Dance!
-
-First, you will need `TAP_DANCE_ENABLE=yes` in your `rules.mk`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. 
+First, you will need `TAP_DANCE_ENABLE = yes` in your `rules.mk`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. 
 
 Optionally, you might want to set a custom `TAPPING_TERM` time by adding something like this in you `config.h`:
 
-```
+```c
 #define TAPPING_TERM 175
 ```
 
-The `TAPPING_TERM` time is the maximum time allowed between taps of your Tap Dance key, and is measured in milliseconds. For example, if you used the above `#define` statement and set up a Tap Dance key that sends `Space` on single-tap and `Enter` on double-tap, then this key will send `ENT` only if you tap this key twice in less than 175ms. If you tap the key, wait more than 175ms, and tap the key again you'll end up sending `SPC SPC` instead.

+For more complicated cases, use the third or fourth options (examples of each are listed below).
 
 Finally, the fifth option is particularly useful if your non-Tap-Dance keys start behaving weirdly after adding the code for your Tap Dance keys.

-## Implementation Details
+## Implementation Details :id=implementation
+
 Well, that's the bulk of it! You should now be able to work through the examples below, and to develop your own Tap Dance functionality. But if you want a deeper understanding of what's going on behind the scenes, then read on for the explanation of how it all works!
 
 The main entry point is `process_tap_dance()`, called from `process_record_quantum()`, which is run for every keypress, and our handler gets to run early. This function checks whether the key pressed is a tap-dance key. If it is not, and a tap-dance was in action, we handle that first, and enqueue the newly pressed key. If it is a tap-dance key, then we check if it is the same as the already active one (if there's one active, that is). If it is not, we fire off the old one first, then register the new one. If it was the same, we increment the counter and reset the timer.
@@ -58,9 +52,9 @@ Our next stop is `matrix_scan_tap_dance()`. This handles the timeout of tap-danc
 
 For the sake of flexibility, tap-dance actions can be either a pair of keycodes, or a user function. The latter allows one to handle higher tap counts, or do extra things, like blink the LEDs, fiddle with the backlighting, and so on. This is accomplished by using an union, and some clever macros.

+The easiest to use method, albeit somewhat limited. It stores Unicode characters as keycodes in the keymap itself, so it only supports code points up to `0x7FFF`. This covers characters for most modern languages (including East Asian), as well as symbols, but it doesn't cover emoji.

-### Lower and Upper Case
+#### Lower and Upper Case
 
 Characters often come in lower and upper case pairs, such as å and Å. To make inputting these characters easier, you can use `XP(i, j)` in your keymap, where _i_ and _j_ are the mapping table indices of the lower and upper case character, respectively. If you're holding down Shift or have Caps Lock turned on when you press the key, the second (upper case) character will be inserted; otherwise, the first (lower case) version will appear.
 
 This is most useful when creating a keymap for an international layout with special characters. Instead of having to put the lower and upper case versions of a character on separate keys, you can have them both on the same key by using `XP()`. This helps blend Unicode keys in with regular alphas.
 
-Due to keycode size constraints, _i_ and _j_ can each only refer to one of the first 128 characters in your `unicode_map`. In other words, 0 ≤ _i_ ≤ 127 and 0 ≤ _j_ ≤ 127. This is enough for most use cases, but if you'd like to customize the index calculation, you can override the [`unicodemap_index()`](https://github.com/qmk/qmk_firmware/blob/71f640d47ee12c862c798e1f56392853c7b1c1a8/quantum/process_keycode/process_unicodemap.c#L40) function.

-## Input Modes
+
+## 2. Input Modes :id=input-modes
 
 Unicode input in QMK works by inputting a sequence of characters to the OS, sort of like a macro. Unfortunately, the way this is done differs for each platform. Specifically, each platform requires a different combination of keys to trigger Unicode input. Therefore, a corresponding input mode has to be set in QMK.
 
 The following input modes are available:
 
-* **`UC_MAC`**: macOS built-in Unicode hex input. Supports code points up to `0xFFFF` (`0x10FFFF` with Unicode Map).
+* **`UC_MAC`**: macOS built-in Unicode hex input. Supports code points up to `0x10FFFF` (all possible code points).
 
   To enable, go to _System Preferences > Keyboard > Input Sources_, add _Unicode Hex Input_ to the list (it's under _Other_), then activate it from the input dropdown in the Menu Bar.
-  By default, this mode uses the left Option key (`KC_LALT`) for Unicode input, but this can be changed by defining [`UNICODE_KEY_MAC`](#input-key-configuration) with another keycode.

+  !> `UC_OSX` is a deprecated alias of `UC_MAC` that will be removed in future versions of QMK. All new keymaps should use `UC_MAC`.
 
 * **`UC_LNX`**: Linux built-in IBus Unicode input. Supports code points up to `0x10FFFF` (all possible code points).
 
   Enabled by default and works almost anywhere on IBus-enabled distros. Without IBus, this mode works under GTK apps, but rarely anywhere else.
-  By default, this mode uses Ctrl+Shift+U (`LCTL(LSFT(KC_U))`) to start Unicode input, but this can be changed by defining [`UNICODE_KEY_LNX`](#input-key-configuration) with another keycode. This might be required for IBus versions ≥1.5.15, where Ctrl+Shift+U behavior is consolidated into Ctrl+Shift+E.

 * **`UC_WIN`**: _(not recommended)_ Windows built-in hex numpad Unicode input. Supports code points up to `0xFFFF`.
 
-  To enable, create a registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad` and set its value to `1`. This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.

This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.
   This mode is not recommended because of reliability and compatibility issues; use the `UC_WINC` mode instead.
 
 * **`UC_BSD`**: _(non implemented)_ Unicode input under BSD. Not implemented at this time. If you're a BSD user and want to help add support for it, please [open an issue on GitHub](https://github.com/qmk/qmk_firmware/issues).
 
 * **`UC_WINC`**: Windows Unicode input using [WinCompose](https://github.com/samhocevar/wincompose). As of v0.9.0, supports code points up to `0x10FFFF` (all possible code points).
 
-  To enable, install the [latest release](https://github.com/samhocevar/wincompose/releases/latest). Once installed, WinCompose will automatically run on startup. Works reliably under all version of Windows supported by the app.
-  By default, this mode uses right Alt (`KC_RALT`) as the Compose key, but this can be changed in the WinCompose settings and by defining [`UNICODE_KEY_WINC`](#input-key-configuration) with another keycode.

-### Switching Input Modes
 
-There are two ways to set the input mode for Unicode: by keycode or by function. Keep in mind that both methods write to persistent storage (EEPROM), and are loaded each time the keyboard starts. So once you've set it the first time, you don't need to set it again unless you want to change it, or you've reset the EEPROM settings.
+## 3. Setting the Input Mode :id=setting-the-input-mode
 
-You can switch the input mode at any time by using one of the following keycodes. The easiest way is to add the ones you use to your keymap.
-
-|Keycode               |Alias    |Input Mode  |Description                                                   |
-|----------------------|---------|------------|--------------------------------------------------------------|
-|`UNICODE_MODE_FORWARD`|`UC_MOD` |Next in list|[Cycle](#input-mode-cycling) through selected modes           |
-|`UNICODE_MODE_REVERSE`|`UC_RMOD`|Prev in list|[Cycle](#input-mode-cycling) through selected modes in reverse|
-|`UNICODE_MODE_MAC`    |`UC_M_MA`|`UC_MAC`    |Switch to macOS input                                         |
-|`UNICODE_MODE_LNX`    |`UC_M_LN`|`UC_LNX`    |Switch to Linux input                                         |

-|`UNICODE_MODE_BSD`    |`UC_M_BS`|`UC_BSD`    |Switch to BSD input (not implemented)                         |
-|`UNICODE_MODE_WINC`   |`UC_M_WC`|`UC_WINC`   |Switch to Windows input using WinCompose                      |
-
-You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`). Since the function only needs to be called once, it's recommended that you do it in `eeconfig_init_user()` (or a similar function). For example:
+To set your desired input mode, add the following define to your `config.h`:
 
 ```c
-void eeconfig_init_user(void) {
-    set_unicode_input_mode(UC_LNX);
-}
+#define UNICODE_SELECTED_MODES UC_LNX
 ```
 
-### Audio Feedback
+This example sets the board's default input mode to `UC_LNX`. You can replace this with `UC_MAC`, `UC_WINC`, or any of the other modes listed [above](#input-modes). The board will automatically use the selected mode on startup, unless you manually switch to another mode (see [below](#keycodes)).
+
+You can also select multiple input modes, which allows you to easily cycle through them using the `UC_MOD`/`UC_RMOD` keycodes.
+
+```c
+#define UNICODE_SELECTED_MODES UC_MAC, UC_LNX, UC_WINC
+```
+
+Note that the values are separated by commas. The board will remember the last used input mode and will continue using it on next power-up. You can disable this and force it to always start with the first mode in the list by adding `#define UNICODE_CYCLE_PERSIST false` to your `config.h`.

+You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`).

+# Docker Quick Start
+
+This project includes a Docker workflow that will allow you to build a new firmware for your keyboard very easily without major changes to your primary operating system. This also ensures that when you clone the project and perform a build, you have the exact same environment as anyone else and the QMK build infrastructure. This makes it much easier for people to help you troubleshoot any issues you encounter.
+
+## Requirements
+
+The main prerequisite is a working `docker` install.
+* [Docker CE](https://docs.docker.com/install/#supported-platforms)
+
+## Usage
+
+Acquire a local copy of the QMK's repository (including submodules):
+
+```bash
+git clone --recurse-submodules https://github.com/qmk/qmk_firmware.git
+cd qmk_firmware
+```
+
+Run the following command to build a keymap:
+```bash
+util/docker_build.sh <keyboard>:<keymap>
+# For example: util/docker_build.sh planck/rev6:default
+```
+
+This will compile the desired keyboard/keymap and leave the resulting `.hex` or `.bin` file in the QMK directory for you to flash. If `:keymap` is omitted, all keymaps are used. Note that the parameter format is the same as when building with `make`.
+
+There is also support for building _and_ flashing the keyboard straight from Docker by specifying the `target` as well:
+
+```bash
+util/docker_build.sh keyboard:keymap:target
+# For example: util/docker_build.sh planck/rev6:default:flash
+```
+
+You can also start the script without any parameters, in which case it will ask you to input the build parameters one by one, which you may find easier to use:
+
+```bash
+util/docker_build.sh
+# Reads parameters as input (leave blank for all keyboards/keymaps)
+```
+
+## FAQ
+
+### Why can't I flash on Windows/macOS
+
+On Windows and macOS, it requires [Docker Machine](http://gw.tnode.com/docker/docker-machine-with-usb-support-on-windows-macos/) to be running. This is tedious to set up, so it's not recommended; use [QMK Toolbox](https://github.com/qmk/qmk_toolbox) instead.
+
+!> Docker for Windows requires [Hyper-V](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v) to be enabled. This means that it cannot work on versions of Windows which don't have Hyper-V, such as Windows 7, Windows 8 and **Windows 10 Home**.

+
+QMK のメンバーがあなたのプルリクエストに返信し、あなたの提出したものは Breaking change (互換性を破る変更) であると述べている場合があります。メンバーの判断では、あなたが提案した変更は QMK やその利用者にとってより大きな影響を持つと考えられます。
+
+プルリクエストにフラグが立てられる原因となるものには、以下のようなものがあります:
+
+- **ユーザーのキーマップに対する編集**
+  ユーザーが自分のキーマップを QMK に提出した後、しばらくしてさらに更新してプルリクエストを開いたところ、それが `qmk/qmk_firmware` リポジトリで編集されていたためにマージできなかったことに気づくことがあるかもしれません。すべてのユーザーが Git や GitHub を使いこなせるわけではないので、ユーザー自身で問題を修正できないことに気づくかもしれません。
+- **期待される動作の変更**
+  QMK の動作を変更すると、既存の QMK 機能への変更を組み込んだ新しいファームウェアをフラッシュした場合、ユーザはハードウェアまたは QMK が壊れていると考え、希望する動作を復元する手段がないことに気付くことがあります。
+- **ユーザーのアクションを必要とする変更**
+  変更には、ツールチェインを更新したり、Git で何らかのアクションを取るなど、ユーザーがアクションを行う必要がある場合もあります。
+- **精査が必要な変更**
+  時には、投稿がプロジェクトとしての QMK に影響を与えることもあります。これは、著作権やライセンスの問題、コーディング規約、大規模な機能のオーバーホール、コミュニティによるより広範なテストを必要とする「リスクの高い」変更、あるいは全く別のものである可能性があります。
+- **エンドユーザーとのコミュニケーションを必要とする変更**
+  これには、将来の非推奨化への警告、時代遅れの慣習、その他伝えなければならないが上記のカテゴリのどれかに当てはまらないものが含まれます。
+
+## 何をすればいいのか?
+
+提出したものが Breaking change だと判断された場合、手続きをスムーズに進めるためにできることがいくつかあります。
+
+### PR を分割することを検討する
+
+あなたがコアコードを投稿していて、それが Breaking change プロセスを経る必要がある唯一の理由が、あなたの変更に合わせてキーマップを更新していることである場合、古いキーマップが機能し続けるような方法であなたの機能を投稿できるかどうかを検討してください。
+そののち、Breaking change プロセスを経て古いコードを削除する別の PR を提出してください。
+
+### ChangeLog エントリの提供
+
+Breaking change プロセスを経て提出する際には、変更ログのエントリを含めることを我々は要請します。
+エントリーは、あなたのプルリクエストが行う変更の短い要約としてください &ndash; [ここの各セクションは changelog として開始されました](ja/ChangeLog/20190830.md "n.b. This should link to the 2019 Aug 30 Breaking Changes doc - @noroadsleft")。
+
+変更ログは `docs/ChangeLog/YYYYMMDD/PR####.md` に置いてください。
+ここで、`YYYYMMDD` は QMK の breaking change ブランチ &ndash; 通常は `develop` という名称 &ndash; が `master` ブランチにマージされる日付、`####` はプルリクエストの番号です。
+
+ユーザー側でのアクションを必要とする場合、あなたの変更ログは、どのようなアクションを取らなければならないかをユーザーに指示するか、そのようなアクションを指示する場所にリンクする必要があります。
+
+### 変更点を文書化する
+
+提出物の目的を理解し、それが必要とする可能性のある意味合いやアクションを理解することで、レビュープロセスをより簡単にすることができます。この目的のためには変更履歴で十分かもしれませんが、より広範囲の変更を行う場合には、変更履歴には不向きな詳細レベルが必要になるかもしれません。
+
+あなたのプルリクエストにコメントしたり、質問やコメント、変更要求に対応したりすることは、非常にありがたいことです。
+
+### 助けを求める
+
+あなたの提出物にフラグが立ったことで、あなたはびっくりしてしまったかもしれません。もし、あなた自身が脅されたり、圧倒されたりしていると感じたら、私たちに知らせてください。プルリクエストにコメントするか、[Discord で QMK チームに連絡を取ってください](https://discord.gg/Uq7gcHh)。

+
+このページでは、QMK Configurator でファームウェアを構築する手順を説明します。
+
+## ステップ 1: キーボードを選ぶ
+
+ドロップダウンボックスをクリックして、キーマップを作成するキーボードを選択します。
+
+?> **キーボードに複数のバージョンがある場合は、正しいバージョンを選択してください。**
+
+大事なことなのでもう一度言います。
+
+!> **正しいバージョンを選択してください!**
+
+キーボードが QMK を搭載していると宣伝されていてもリストにない場合は、開発者がまだ作業中か、私たちがまだマージするきっかけがなかった可能性があります。
+アクティブな [プルリクエスト](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+is%3Apr+label%3Akeyboard) がない場合、[qmk_firmware](https://github.com/qmk/qmk_firmware/issues)で報告して、その特定のキーボードのサポートをリクエストします。
+製作者自身の GitHub アカウントにある QMK 搭載キーボードもあります。
+それも再確認してください。
+
+## ステップ2: キーボードのレイアウトを選択する
+
+作成したいと思うキーマップに最も近いレイアウトを選択します。一部のキーボードには、まだ十分なレイアウトや正しいレイアウトが定義されていません。これらは将来サポートされる予定です。
+
+## ステップ3: キーマップの名前を決める
+
+お好みの名前をキーマップにつけます。
+
+?> コンパイル時に問題が発生した場合は、もしかすると QMK ファームウェアリポジトリに既に同じ名前が存在しているのかもしれません。名前を変更してみてください。
+
+## ステップ4: キーマップを定義する
+
+キーコードの入力は、3つの方法のいずれかで行います。
+
+1. ドラッグ・アンド・ドロップ
+2. レイアウト上の空の場所をクリックして、希望するキーコードをクリックします
+3. レイアウト上の空の場所をクリックして、キーボードの物理キーを押します
+
+?> マウスをキーの上に置くと、そのキーコードの機能の短い説明文が出ます。より詳細な説明については以下を見てください:
+
+* [基本的なキーコードリファレンス](ja/keycodes_basic.md)
+* [高度なキーコードリファレンス](ja/feature_advanced_keycodes.md)
+
+!> 選択したレイアウトが物理的なビルドと一致しない場合は、使用していないキーは空白のままにしておきます。どのキーが使用されているかわからない場合、例えば、バックスペースキーは1つだが `LAYOUT_all` には2つのキーがある場合は、同じキーコードを両方の場所に配置してください。
+
+## ステップ5: 後日のためにキーマップを保存する
+
+キーマップに満足するか、または後で作業したい場合は、`Export Keymap' ボタンを押します。
+これでキーマップがあなたのコンピュータに保存されます。
+その後、`Import Keymap` ボタンを押すことで、この .json ファイルを後で読み込むことができます。
+
+!> **注意:** このファイルは、kbfirmware.com またはその他のツールに使用される .json ファイルと同じ形式ではありません。これらのツールにこの .json を使用したり、QMK Configurator でこれらのツールの .json を使用しようとすると、問題が発生します。
+
+## ステップ6: ファームウェアをコンパイルする
+
+緑色の `Compile` ボタンを押します。
+
+コンパイルが完了すると、緑色の `Download Firmware` ボタンを押すことができます。
+
+## 次のステップ: キーボードに書き込む(フラッシュする)
+
+[ファームウェアを書きこむ](ja/newbs_flashing.md) を参照してください。

+
+# ページの開始
+
+ドキュメントページは通常 H1 ヘッダで始まり、最初の段落を使ってこのページの内容を説明します。この見出しと段落は目次の次にあるため、見出しは短くして空白の無い長い文字列を避けるように気を付けてください。
+

+This page covers my super cool feature. You can use this feature to make coffee, squeeze fresh oj, and have an egg mcmuffin and hashbrowns delivered from your local macca's by drone.
+```
+
+# 見出し
+
+通常、ページには複数の "H1" 見出しが有るべきです。H1 と H2 見出しのみが目次に含まれるので、適切に計画してください。目次が広くなりすぎないように、H1 と H2 の見出しでは幅を広げないようにしてください。

-これらの機能により、様々な方法でレイヤーをアクティブ化することができます。レイヤーは一般的に独立したレイアウトでは無いことに注意してください -- 複数のレイヤーを一度にアクティブ化することができ、レイヤーが `KC_TRNS` を使ってキーの押下を下のレイヤーに渡すことが一般的です。レイヤーの詳細については、[キーマップの概要](ja/keymap.md#keymap-and-layers)を見てください。MO()、LM()、TT() あるいは LT() を使って一時的なレイヤーの切り替えを使う場合、上のレイヤーのキーを透過にするようにしてください。さもないと意図したように動作しないかもしれません。
-
-* `DF(layer)` - デフォルトレイヤーを切り替えます。デフォルトレイヤーは、他のレイヤーがその上に積み重なっている、常にアクティブな基本レイヤーです。デフォルトレイヤーの詳細については以下を見てください。これは QWERTY から Dvorak レイアウトに切り替えるために使うことができます。(これは一時的な切り替えであり、キーボードの電源が切れるまでしか持続しないことに注意してください。デフォルトレイヤーを永続的に変更するには、[process_record_user](ja/custom_quantum_functions.md#programming-the-behavior-of-any-keycode) 内で `set_single_persistent_default_layer` 関数を呼び出すなど、より深いカスタマイズが必要です。)
-* `MO(layer)` - 一時的に*レイヤー*をアクティブにします。キーを放すとすぐに、レイヤーは非アクティブになります。
-* `LM(layer, mod)` - (`MO` のように)一時的に*レイヤー*をアクティブにしますが、モディファイア *mod* がアクティブな状態です。layer 0-15 と、左モディファイアのみをサポートします: `MOD_LCTL`、`MOD_LSFT`、`MOD_LALT`、`MOD_LGUI` (`KC_` の代わりに `MOD_` 定数を使うことに注意してください)。これらのモディファイアは、例えば `LM(_RAISE, MOD_LCTL | MOD_LALT)` のように、ビット単位の OR を使って組み合わせることができます。
-* `LT(layer, kc)` - ホールドされた時に*レイヤー*を一時的にアクティブにし、タップされた時に *kc* を送信します。layer 0-15 のみをサポートします。
-* `OSL(layer)` - 次のキーが押されるまで、一時的に*レイヤー*をアクティブにします。詳細と追加機能については、[ワンショットキー](ja/one_shot_keys.md)を見てください。
-* `TG(layer)` - *レイヤー*を切り替えます。非アクティブな場合はアクティブにし、逆も同様です。
-* `TO(layer)` - *レイヤー*をアクティブにし、他の全てのレイヤー(デフォルトレイヤーを除く)を非アクティブにします。この関数は特別です。1つのレイヤーをアクティブなレイヤースタックに追加/削除する代わりに、現在のアクティブなレイヤーを完全に置き換え、唯一上位のレイヤーを下位のレイヤーで置き換えることができるからです。これはキーダウンで(キーが押されるとすぐに)アクティブになります。
-* `TT(layer)` - レイヤーのタップ切り替え。キーを押したままにすると*レイヤー*がアクティブにされ、放すと非アクティブになります (`MO` 風)。繰り返しタップすると、レイヤーはオンあるいはオフを切り替えます (`TG` 風)。デフォルトでは5回のタップが必要ですが、`TAPPING_TOGGLE` を定義することで変更することができます -- 例えば、2回のタップだけで切り替えるには、`#define TAPPING_TOGGLE 2` を定義します。
-
-## 注意事項
-
-現在のところ、`LT()` と `MT()` は[基本的なキーコードセット](ja/keycodes_basic.md)に制限されています。つまり、`LCTL()`、`KC_TILD` あるいは `0xFF` より大きなキーコードを使うことができません。レイヤータップあるいはモッドタップのキーコードの一部として指定されたモディファイアは無視されます。タップしたキーコードにモディファイアを適用する必要がある場合は、[タップダンス](ja/feature_tap_dance.md#example-5-using-tap-dance-for-advanced-mod-tap-and-layer-tap-keys)を使うことができます。
-
-さらに、モッドタップあるいはレイヤータップで少なくとも1つの右手用のモディファイアが指定された場合、指定された全てのモディファイアが右手用になるため、2つをうまく組み合わせて一致させることはできません。
-
-# レイヤーの使用
-
-レイヤーを切り替える時は注意してください。(キーボードを取り外さずに)そのレイヤーを非アクティブにすることができずレイヤーから移動できなくなる可能性があります。最も一般的な問題を避けるためのガイドラインを作成しました。
-
-## 初心者
-
-QMK を使い始めたばかりの場合は、全てを単純にしたいでしょう。レイヤーをセットアップする時は、これらのガイドラインに従ってください:
-
-* デフォルトの "base" レイヤーとして、layer 0 をセットアップします。これは通常の入力レイヤーであり、任意のレイアウト (qwerty、dvorak、colemak など)にすることができます。通常はキーボードのキーのほとんどまたは全てが定義されているため、これを最下位のレイヤーとして設定することが重要です。そうすることで、もしそれが他のレイヤーの上 (つまりレイヤー番号が大きい)にある場合の影響を防ぎます。
-* layer 0 をルートとして、レイヤーを "ツリー" レイアウトに配置します。他の複数のレイヤーから同じレイヤーに行こうとしないでください。
-* 各レイヤーのキーマップでは、より高い番号のレイヤーのみを参照します。レイヤーは最大の番号(最上位)のアクティブレイヤーから処理されるため、下位レイヤーの状態を変更するのは難しくエラーが発生しやすくなります。
-
-## 中級ユーザ
-
-複数の基本レイヤーが必要な場合があります。例えば、QWERTY と Dvorak を切り替える場合、国ごとに異なるレイアウトを切り替える場合、あるいは異なるビデオゲームごとにレイアウトを切り替える場合などです。基本レイヤーは常に最小の番号のレイヤーである必要があります。複数の基本レイヤーがある場合、常にそれらを相互排他的に扱う必要があります。1つの基本レイヤーがオンの場合、他をオフにします。
-
-## 上級ユーザ
-
-レイヤーがどのように動作し、何ができるかを理解したら、より創造的になります。初心者のセクションで列挙されている規則は、幾つかの巧妙な詳細を回避するのに役立ちますが、特に超コンパクトなキーボードのユーザにとって制約になる場合があります。レイヤーの仕組みを理解することで、レイヤーをより高度な方法で使うことができます。
-
-レイヤーは番号順に上に積み重なっています。キーの押下の動作を決定する時に、QMK は上から順にレイヤーを走査し、`KC_TRNS` に設定されていない最初のアクティブなレイヤーに到達すると停止します。結果として、現在のレイヤーよりも数値的に低いレイヤーをアクティブにし、現在のレイヤー(あるいはアクティブでターゲットレイヤーよりも高い別のレイヤー)に `KC_TRNS` 以外のものがある場合、それが送信されるキーであり、アクティブ化したばかりのレイヤー上のキーではありません。これが、ほとんどの人の "なぜレイヤーが切り替わらないのか" 問題の原因です。
-
-場合によっては、マクロ内あるいはタップダンスルーチンの一部としてレイヤーを切り替えほうが良いかもしれません。`layer_on` はレイヤーをアクティブにし、`layer_off` はそれを非アクティブにします。もっと多くのレイヤーに関する関数は、[action_layer.h](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/action_layer.h) で見つけることができます。

 両方のタイマーがオーディオのために使われている場合、バックライト PWM はハードウェアタイマを使いませんが、代わりにマトリックススキャンの間に引き起こされます。この場合、PWM の計算は十分なタイミングの精度で呼ばれないかもしれないため、バックライトの明滅はサポートされず、バックライトもちらつくかもしれません。

+
+コンボ機能は、同時押し方式でのカスタムアクション追加機能です。同時に複数のキーを押して、異なる効果を生み出すことができます。例えば、タッピング時間内で `A` と `S` を押すと、代わりに `ESC` が押されます。もっと複雑なタスクを実行させることもできます。
+
+この機能を有効にするには、`rules.mk` に `COMBO_ENABLE = yes` を追加する必要があります。
+
+さらに、使用するコンボの数を `config.h` の中で、`#define COMBO_COUNT 1` (1を使用するコンボの数で置き換えます)と書いて、指定する必要があります。
+<!-- At this time, this is necessary -->
+
+また、デフォルトでは、コンボのタッピング時間は `TAPPING_TERM` と同じ値に設定されます (ほとんどのキーボードではデフォルトで 200)。ただし、`config.h` で定義することにより異なる値を指定することができます。例えば: `#define COMBO_TERM 300` はコンボのためのタイムアウト時間を 300ms に設定します。
+
+次に、`keymap.c` ファイルに、`COMBO_END` で終了するキーのシーケンス、およびキーの組み合わせを列挙する構造体、その結果のアクションを定義する必要があります。
+
+```c
+const uint16_t PROGMEM test_combo[] = {KC_A, KC_B, COMBO_END};
+combo_t key_combos[COMBO_COUNT] = {COMBO(test_combo, KC_ESC)};
+```
+
+これは、A と B のキーを押した場合に、"Escape" を送信します。
+
+!> このメソッドは[基本的なキーコード](ja/keycodes_basic.md)のみをサポートします。詳細な制御については例を見てください。
+
+## 例
+
+リストを追加したい場合は、以下のようなものを使います:
+
+```c
+enum combos {
+  AB_ESC,
+  JK_TAB
+};
+
+const uint16_t PROGMEM ab_combo[] = {KC_A, KC_B, COMBO_END};
+const uint16_t PROGMEM jk_combo[] = {KC_J, KC_K, COMBO_END};
+
+combo_t key_combos[COMBO_COUNT] = {
+  [AB_ESC] = COMBO(ab_combo, KC_ESC),
+  [JK_TAB] = COMBO(jk_combo, KC_TAB)
+};
+```
+
+より複雑な実装として、カスタム処理を追加するために `process_combo_event` 関数を使うことができます。
+
+```c
+enum combo_events {
+  ZC_COPY,
+  XV_PASTE
+};
+
+const uint16_t PROGMEM copy_combo[] = {KC_Z, KC_C, COMBO_END};
+const uint16_t PROGMEM paste_combo[] = {KC_X, KC_V, COMBO_END};
+
+combo_t key_combos[COMBO_COUNT] = {
+  [ZC_COPY] = COMBO_ACTION(copy_combo),
+  [XV_PASTE] = COMBO_ACTION(paste_combo),
+};
+
+void process_combo_event(uint8_t combo_index, bool pressed) {
+  switch(combo_index) {
+    case ZC_COPY:
+      if (pressed) {
+        tap_code16(LCTL(KC_C));
+      }
+      break;
+    case XV_PASTE:
+      if (pressed) {
+        tap_code16(LCTL(KC_V));
+      }
+      break;
+  }
+}
+```
+
+これは、Z と C を押すと Ctrl+C を送信し、X と V を押すと Ctrl+V を送信します。これを変更して、レイヤーの変更、サウンドの再生、設定の変更などを行うこともできます。
+
+## 追加の設定
+
+長いコンボあるいはさらに長いコンボを使っている場合、構造体があなたのしていることに対応するのに十分な大きさで無いかもしれないため、問題が発生するかもしれません。
+
+この場合、`config.h` ファイルに `#define EXTRA_LONG_COMBOS` または `#define EXTRA_EXTRA_LONG_COMBOS` のどちらかを追加することができます。
+
+`COMBO_ALLOW_ACTION_KEYS` を定義することでアクションキーを有効にすることもできます。

+| `CMB_OFF` | コンボ機能をオフにします |
