+# QMK Breaking Changes - 2021 August 28 Changelog
+
+## Notable Features :id=notable-features
+
+### Combo processing improvements ([#8591](https://github.com/qmk/qmk_firmware/pull/8591)) :id=combo-processing-improvements
+
+Combo processing has been reordered with respect to keypress handling, allowing for much better compatibility with mod taps.
+
+It is also now possible to define combos that have keys overlapping with other combos, triggering only one. For example, a combo of `A`, `B` can coexist with a longer combo of `A`, `B`, `C` -- previous functionality would trigger both combos if all three keys were pressed.
+
+### Key Overrides ([#11422](https://github.com/qmk/qmk_firmware/pull/11422)) :id=key-overrides
+
+QMK now has a new feature: [key overrides](https://docs.qmk.fm/#/feature_key_overrides). This feature allows for overriding the output of key combinations involving modifiers. As an example, pressing <kbd>Shift+2</kbd> normally results in an <kbd>@</kbd> on US-ANSI keyboard layouts -- the new key overrides allow for adding similar functionality, but for any <kbd>modifier + key</kbd> press.
+
+To illustrate, it's now possible to use the key overrides feature to translate <kbd>Shift + Backspace</kbd> into <kbd>Delete</kbd> -- an often-requested example of where this functionality comes in handy.
+
+There's far more to describe that what lives in this changelog, so head over to the [key overrides documentation](https://docs.qmk.fm/#/feature_key_overrides) for more examples and info.
+
+### Digitizer support ([#12851](https://github.com/qmk/qmk_firmware/pull/12851))
+
+QMK gained the ability to pretend to be a digitizer device -- much like a tablet device. A mouse uses delta-coordinates -- move up, move right -- but a digitizer works with absolute coordinates -- top left, bottom right.

+
+### Bootmagic Full Removal ([#13846](https://github.com/qmk/qmk_firmware/pull/13846)) :id=bootmagic-full-removal
+
+As noted during last breaking changes cycle, QMK has decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.
+
+This pull request changes the behavior of `BOOTMAGIC_ENABLE` such that specifying `full` results in an error, allowing only `no`, `yes`, or `lite`.
+
+Next cycle, `lite` will be removed, so `yes` and `no` should be used in to minimise disruption.
+
+#### Bootmagic Full Deprecation Schedule
+
+This is the current roadmap for the behavior of `BOOTMAGIC_ENABLE`:
+
+- (done) From 2021 May 29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- (now) From 2021 Aug 28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- (next) From 2021 Nov 27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.
+
+### DIP switch callbacks are now boolean ([#13399](https://github.com/qmk/qmk_firmware/pull/13399)) :id=dip-switch-boolean
+
+To match the encoder change last breaking changes cycle, DIP switch callbacks now return `bool`, too.
+
+Example code before change:
+
+```c
+void dip_switch_update_kb(uint8_t index, bool active) {
+    dip_switch_update_user(index, active);
+}
+
+void dip_switch_update_user(uint8_t index, bool active) {
+    switch (index) {
+        case 0:
+            if(active) { audio_on(); } else { audio_off(); }
+            break;
+    }
+}
+
+void dip_switch_update_mask_kb(uint32_t state) { 
+    dip_switch_update_mask_user(state);
+}
+
+void dip_switch_update_mask_user(uint32_t state) {
+    if (state & (1UL<<0) && state & (1UL<<1)) {
+        layer_on(_ADJUST); // C on esc
+    } else {
+        layer_off(_ADJUST);
+    }
+}
+```
+
+Example code after change:
+
+```c
+bool dip_switch_update_kb(uint8_t index, bool active) {
+    if !(dip_switch_update_user(index, active)) { return false; }
+    return true;
+}
+
+bool dip_switch_update_user(uint8_t index, bool active) {
+    switch (index) {
+        case 0:
+            if(active) { audio_on(); } else { audio_off(); }
+            break;
+    }
+    return true; // Returning true allows keyboard code to execute, false will tell the keyboard code "I've already handled it".
+}
+
+bool dip_switch_update_mask_kb(uint32_t state) {
+    if (!dip_switch_update_mask_user(state)) { return false; }
+    return true;
+}
+
+bool dip_switch_update_mask_user(uint32_t state) {
+    if (state & (1UL<<0) && state & (1UL<<1)) {
+        layer_on(_ADJUST); // C on esc
+    } else {
+        layer_off(_ADJUST);
+    }
+    return true; // Returning true allows keyboard code to execute, false will tell the keyboard code "I've already handled it".
+}
+```
+
+## Notable core changes :id=notable-core
+
+### Split transport improvements :id=split-transport-improvements
+
+Split keyboards gained a significant amount of improvements during this breaking changes cycle, specifically:
+
+* Extensible split data sync ([#11930](https://github.com/qmk/qmk_firmware/pull/11930)) -- rewritten data sharing between sides, allowing for data transfer only when required, as well as enabling keyboards and keymaps to define their own shared data.
+* Full-duplex ARM USART split ([#13081](https://github.com/qmk/qmk_firmware/pull/13081)) -- adds to the previous half-duplex driver and now allows for full-duplex support on ARM.
+* Make solo half of split keyboards (more) usable. ([#13523](https://github.com/qmk/qmk_firmware/pull/13523)) -- allows the slave to be disconnected, enabling one-handed use.
+* Switch split_common to CRC subsystem ([#13418](https://github.com/qmk/qmk_firmware/pull/13418))
+
+!> If you're updating your split keyboard, you will need to flash both sides of the split with the your firmware.
+
+### Teensy 4.x support ([#13056](https://github.com/qmk/qmk_firmware/pull/13056), [#13076](https://github.com/qmk/qmk_firmware/pull/13076), [#13077](https://github.com/qmk/qmk_firmware/pull/13077)) :id=teensy-4-x-support
+
+Updated ChibiOS and ChibiOS-Contrib, which brought in support for Teensy 4.x dev boards, running NXP i.MX1062.
+
+### Data Driven Improvements ([#13366](https://github.com/qmk/qmk_firmware/pull/13366))
+
+QMK's pursuit of data-driven keyboards has progressed, allowing substantially more configurable options to be specified in `info.json`.
+
+#### Tags
+
+Tags will let you categorize your keyboard, and will be used in the future to allow browsing and sorting through keyboards in QMK. Tags are free-form text identifiers that identify attributes about your keyboard. To add tags you simply add a `tags` key to your `info.json`:
+
+    "tags": ["tkl", "backlight", "encoder"]
+
+#### Dot Notation
+
+With this release we are moving towards using JSON dot notation in more places. For example, when using `qmk info -f text`:
+
+```
+$ qmk info -f text -kb clueboard/card
+  bootloader: atmel-dfu
+  debounce: 20
+  diode_direction: ROW2COL
+  features.audio: True
+  features.backlight: True
+  features.bluetooth: False
+  features.bootmagic: False
+  features.command: True
+  features.console: True
+  features.extrakey: True

+# ChibiOS Upgrade Procedure
+
+ChibiOS and ChibiOS-Contrib need to be updated in tandem -- the latter has a branch tied to the ChibiOS version in use and should not be mixed with different versions.
+
+## Getting ChibiOS
+
+* `svn` Initialisation:
+    * Only needed to be done once
+    * You might need to separately install `git-svn` package in your OS's package manager
+    * `git svn init --stdlayout --prefix='svn/' http://svn.osdn.net/svnroot/chibios/`
+    * `git remote add qmk git@github.com:qmk/ChibiOS.git`
+* Updating:
+    * `git svn fetch`
+    * First time around this will take several hours
+    * Subsequent updates will be incremental only
+* Tagging example (work out which version first!):
+    * `git tag -a ver20.3.3 -m ver20.3.3 svn/tags/ver20.3.3`
+    * `git push qmk ver20.3.3`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN svn/tags/ver20.3.3`
+    * `git push qmk breaking_YYYY_qN`
+
+## Getting ChibiOS-Contrib
+
+* `git` Initialisation:
+    * `git clone git@github.com:qmk/ChibiOS-Contrib`
+    * `git remote add upstream https://github.com/ChibiOS/ChibiOS-Contrib`
+    * `git checkout -b chibios-20.3.x upstream/chibios-20.3.x`
+* Updating:
+    * `git fetch --all --tags --prune`
+    * `git checkout chibios-20.3.x`
+    * `git pull --ff-only`
+    * `git push origin chibios-20.3.x`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN chibios-20.3.x`
+    * `git push origin breaking_YYYY_qN`
+
+## Updating submodules
+
+* Update the submodules
+    * `cd $QMK_FIRMWARE`
+    * `git checkout develop`
+    * `git pull --ff-only`
+    * `git checkout -b chibios-version-bump`
+    * `cd lib/chibios`
+    * `git fetch --all --tags --prune`
+    * `git checkout breaking_YYYY_qN`

+# Easy Maker - Build One-Off Projects In Configurator
+
+Have you ever needed an easy way to program a controller, such as a Proton C or Teensy 2.0, for a one-off project you're building? QMK has you covered with the Easy Maker. Now you can create a firmware in minutes using QMK Configurator.
+
+There are different styles of Easy Maker available depending on your needs:
+
+* [Direct Pin](https://config.qmk.fm/#/?filter=ez_maker/direct) - Connect a single switch to a single pin
+* Direct Pin + Backlight (Coming Soon) - Like Direct Pin but dedicates a single pin to [Backlight](feature_backlight.md) control
+* Direct Pin + Numlock (Coming Soon) - Like Direct Pin but dedicates a single pin to the Numlock LED
+* Direct Pin + Capslock (Coming Soon) - Like Direct Pin but dedicates a single pin to the Numlock LED
+* Direct Pin + Encoder (Coming Soon) - Like Direct Pin but uses 2 pins to add a single rotary encoder
+
+## Quickstart
+
+The easiest way to get started is with the Direct Pin boards. This will assign a single key to each pin and you can short that pin to ground to activate it. Select your MCU from the Keyboard dropdown here:
+
+* <https://config.qmk.fm/#/?filter=ez_maker/direct>
+
+For more details see the [Direct Pin](#direct-pin) section.
+
+# Direct Pin
+
+As its name implies Direct Pin works by connecting one switch per pin. The other side of the switch should be connected to ground (VSS or GND.) You don't need any other components, your MCU has internal pull-up resistors so that the switch sensing can work.
+
+Here is a schematic showing how we connect a single button to pin A3 on a ProMicro:
+
+![Schematic diagram showing a ProMicro with a wire coming out of A3, connecting to the left side of a switch. Another wire comes out of the right side of the switch to connect to the Ground Plane.](https://i.imgur.com/JcDhZll.png)
+
+Once you have wired your switches you can assign keycodes to each pin and build a firmware by selecting the MCU you are using from the Keyboard dropdown. Use this link to show only Easy Maker Direct Pin:

If a WP pin is configured, then having an external pull-up on the WP pin is recommended.

-# Bootmagic
-
-There are three separate but related features that allow you to change the behavior of your keyboard without reflashing. While each of them have similar functionality, it is accessed in different ways depending on how your keyboard is configured.
-
-**Bootmagic** is a system for configuring your keyboard while it initializes. To trigger a Bootmagic command, hold down the Bootmagic key and one or more command keys.
-
-**Bootmagic Keycodes** are prefixed with `MAGIC_`, and allow you to access the Bootmagic functionality *after* your keyboard has initialized. To use the keycodes, assign them to your keymap as you would any other keycode.
-
-**Command**, formerly known as **Magic**, is another feature that allows you to control different aspects of your keyboard. While it shares some functionality with Bootmagic, it also allows you to do things that Bootmagic does not, such as printing version information to the console. For more information, see [Command](feature_command.md).
-
-On some keyboards Bootmagic is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk` with:
-
-```make
-BOOTMAGIC_ENABLE = full
-```
-
-?> You may see `yes` being used in place of `full`, and this is okay. However, `yes` is deprecated, and ideally `full` (or `lite`) should be used instead.
-
-Additionally, you can use [Bootmagic Lite](#bootmagic-lite) (a scaled down, very basic version of Bootmagic) by adding the following to your `rules.mk` file:
-
-```make
-BOOTMAGIC_ENABLE = lite
-```
-
-## Hotkeys
-
-Hold down the Bootmagic key (Space by default) and the desired hotkey while plugging in your keyboard. For example, holding Space+`B` should cause it to enter the bootloader.

+To manipulate settings that were formerly configured through the now-deprecated full Bootmagic feature, see [Magic Keycodes](keycodes_magic.md).
+
+The Command feature, formerly known as Magic, also allows you to control different aspects of your keyboard. While it shares some functionality with Magic Keycodes, it also allows you to do things that Magic Keycodes cannot, such as printing version information to the console.

-## Additional Configuration
+It is worth noting that `COMBO_ACTION`s are not needed anymore. As of [PR#8591](https://github.com/qmk/qmk_firmware/pull/8591/), it is possible to run your own custom keycodes from combos. Just define the custom keycode, program its functionality in `process_record_user`, and define a combo with `COMBO(<key_array>, <your_custom_keycode>)`.
 
-If you're using long combos, or even longer combos, you may run into issues with this, as the structure may not be large enough to accommodate what you're doing.

 |`CMB_TOG` |Toggles Combo feature on and off |
 
+# Advanced Configuration
+These configuration settings can be set in your `config.h` file.
+
+## Combo Term
+By default, the timeout for the Combos to be recognized is set to 50ms. This can be changed if accidental combo misfires are happening or if you're having difficulties pressing keys at the same time. For instance, `#define COMBO_TERM 40` would set the timeout period for combos to 40ms.
+
+## Buffer and state sizes
+If you're using long combos, or you have a lot of overlapping combos, you may run into issues with this, as the buffers may not be large enough to accommodate what you're doing. In this case, you can configure the sizes of the buffers used. Be aware, larger combo sizes and larger buffers will increase memory usage!
+
+To configure the amount of keys a combo can be composed of, change the following:
+
+| Keys | Define to be set                  |
+|------|-----------------------------------|
+| 6    | `#define EXTRA_SHORT_COMBOS`      |
+| 8    | QMK Default                       |
+| 16   | `#define EXTRA_LONG_COMBOS`       |
+| 32   | `#define EXTRA_EXTRA_LONG_COMBOS` |
+
+Defining `EXTRA_SHORT_COMBOS` combines a combo's internal state into just one byte. This can, in some cases, save some memory. If it doesn't, no point using it. If you do, you also have to make sure you don't define combos with more than 6 keys.
+
+Processing combos has two buffers, one for the key presses, another for the combos being activated. Use the following options to configure the sizes of these buffers:
+
+| Define                              | Default                                              |
+|-------------------------------------|------------------------------------------------------|
+| `#define COMBO_KEY_BUFFER_LENGTH 8` | 8 (the key amount `(EXTRA_)EXTRA_LONG_COMBOS` gives) |
+| `#define COMBO_BUFFER_LENGTH 4`     | 4                                                    |
+
+## Modifier Combos
+If a combo resolves to a Modifier, the window for processing the combo can be extended independently from normal combos. By default, this is disabled but can be enabled with `#define COMBO_MUST_HOLD_MODS`, and the time window can be configured with `#define COMBO_HOLD_TERM 150` (default: `TAPPING_TERM`). With `COMBO_MUST_HOLD_MODS`, you cannot tap the combo any more which makes the combo less prone to misfires.
+
+## Per Combo Timing, Holding and Tapping
+For each combo, it is possible to configure the time window it has to pressed in, if it needs to be held down, or if it needs to be tapped.
+
+For example, tap-only combos are useful if any (or all) of the underlying keys is a Mod-Tap or a Layer-Tap key. When you tap the combo, you get the combo result. When you press the combo and hold it down, the combo doesn't actually activate. Instead the keys are processed separately as if the combo wasn't even there.
+
+In order to use these features, the following configuration options and functions need to be defined. Coming up with useful timings and configuration is left as an exercise for the reader.
+
+| Config Flag                 | Function                                                  | Description                                                                                            |

+| `COMBO_MUST_HOLD_PER_COMBO` | bool get_combo_must_hold(uint16_t index, combo_t \*combo) | Controls if a given combo should fire immediately on tap or if it needs to be held. (default: `false`) |

+    // decide by combo->keycode
+    switch (combo->keycode) {
+        case KC_X:
+            return 50;
+    }
+
+    // or with combo index, i.e. its name from enum.
+    switch (index) {
+        case COMBO_NAME_HERE:

+    }
+
+    // And if you're feeling adventurous, you can even decide by the keys in the chord,
+    // i.e. the exact array of keys you defined for the combo.
+    // This can be useful if your combos have a common key and you want to apply the
+    // same combo term for all of them.
+    if (combo->keys[0] == KC_ENTER) { // if first key in the array is KC_ENTER

+    }
+
+    switch (index) {
+        case COMBO_NAME_HERE:
+            return true;
+    }
+
+    return false;
+}
+
+bool get_combo_must_tap(uint16_t index, combo_t *combo) {
+    // If you want all combos to be tap-only, just uncomment the next line
+    // return true
+
+    // If you want *all* combos, that have Mod-Tap/Layer-Tap/Momentary keys in its chord, to be tap-only, this is for you:
+    uint16_t key;
+    uint8_t idx = 0;
+    while ((key = pgm_read_word(&combo->keys[idx])) != COMBO_END) {

+        }
+        idx += 1;
+    }
+    return false;
+
+}
+```
+
+## Variable Length Combos
+If you leave `COMBO_COUNT` undefined in `config.h`, it allows you to programmatically declare the size of the Combo data structure and avoid updating `COMBO_COUNT`. Instead a variable called `COMBO_LEN` has to be set. It can be set with something similar to the following in `keymap.c`: `uint16_t COMBO_LEN = sizeof(key_combos) / sizeof(key_combos[0]);` or by adding `COMBO_LENGTH` as the *last* entry in the combo enum and then `uint16_t COMBO_LEN = COMBO_LENGTH;` as such:
+```c
+enum myCombos {
+    ...,
+    COMBO_LENGTH
+};
+uint16_t COMBO_LEN = COMBO_LENGTH;
+```
+Regardless of the method used to declare `COMBO_LEN`, this also requires to convert the `combo_t key_combos[COMBO_COUNT] = {...};` line to `combo_t key_combos[] = {...};`.
+
+
+## Combo timer
+
+Normally, the timer is started on the first key press and then reset on every subsequent key press within the `COMBO_TERM`.
+Inputting combos is relaxed like this, but also slightly more prone to accidental misfires.
+
+The next two options alter the behaviour of the timer.
+
+### `#define COMBO_STRICT_TIMER`
+
+With `COMBO_STRICT_TIMER`, the timer is started only on the first key press.
+Inputting combos is now less relaxed; you need to make sure the full chord is pressed within the `COMBO_TERM`.
+Misfires are less common but if you type multiple combos fast, there is a
+chance that the latter ones might not activate properly.
+
+### `#define COMBO_NO_TIMER`
+
+By defining `COMBO_NO_TIMER`, the timer is disabled completely and combos are activated on the first key release.
+This also disables the "must hold" functionalities as they just wouldn't work at all.
+
+## Customizable key releases
+
+By defining `COMBO_PROCESS_KEY_RELEASE` and implementing the function `bool process_combo_key_release(uint16_t combo_index, combo_t *combo, uint8_t key_index, uint16_t keycode)`, you can run your custom code on each key release after a combo was activated. For example you could change the RGB colors, activate haptics, or alter the modifiers.
+
+You can also release a combo early by returning `true` from the function.
+
+Here's an example where a combo resolves to two modifiers, and on key releases the modifiers are unregistered one by one, depending on which key was released.
+
+```c
+enum combos {
+  AB_MODS,
+  COMBO_LENGTH
+};
+uint16_t COMBO_LEN = COMBO_LENGTH;
+
+const uint16_t PROGMEM ab_combo[] = {KC_A, KC_B, COMBO_END};
+
+combo_t key_combos[] = {
+  [AB_MODS] = COMBO(ab_combo, LCTL(KC_LSFT)),
+};
+
+bool process_combo_key_release(uint16_t combo_index, combo_t *combo, uint8_t key_index, uint16_t keycode) {
+    switch (combo_index) {
+        case AB_MODS:
+            switch(keycode) {
+                case KC_A:
+                    unregister_mods(MOD_MASK_CTRL);
+                    break;
+                case KC_B:
+                    unregister_mods(MOD_MASK_SHIFT);
+                    break;
+            }
+            return false; // do not release combo
+    }
+    return false;
+}
+```
+## Layer independent combos
+
+If you, for example, use multiple base layers for different key layouts, one for QWERTY, and another one for Colemak, you might want your combos to work from the same key positions on all layers. Defining the same combos again for another layout is redundant and takes more memory. The solution is to just check the keycodes from one layer.
+
+With `#define COMBO_ONLY_FROM_LAYER _LAYER_A` the combos' keys are always checked from layer `_LAYER_A` even though the active layer would be `_LAYER_B`.
+
 ## User callbacks

+# Dictionary Management
+
+Having 3 places to update when adding new combos or altering old ones does become cumbersome when you have a lot of combos. We can alleviate this with some magic! ... If you consider C macros magic.
+First, you need to add `VPATH += keyboards/gboards` to your `rules.mk`. Next, include the file `g/keymap_combo.h` in your `keymap.c`.
+
+!> This functionality uses the same `process_combo_event` function as `COMBO_ACTION` macros do, so you cannot use the function yourself in your keymap. Instead, you have to define the `case`s of the `switch` statement by themselves within `inject.h`, which `g/keymap_combo.h` will then include into the function.
+
+Then, write your combos in `combos.def` file in the following manner:
+
+```c
+//   name     result    chord keys
+COMB(AB_ESC,   KC_ESC,   KC_A, KC_B)
+COMB(JK_TAB,   KC_TAB,   KC_J, KC_K)
+COMB(JKL_SPC,  KC_SPC,   KC_J, KC_K, KC_L)
+COMB(BSSL_CLR, KC_NO,    KC_BSPC, KC_LSFT) // using KC_NO as the resulting keycode is the same as COMBO_ACTION before.
+COMB(QW_UNDO,  C(KC_Z),  KC_Q, KC_W)
+SUBS(TH_THE,   "the",    KC_T, KC_H) // SUBS uses SEND_STRING to output the given string.
+...
+```
+
+Now, you can update only one place to add or alter combos. You don't even need to remember to update the `COMBO_COUNT` or the `COMBO_LEN` variables at all. Everything is taken care of. Magic!

+## Digitizer
+
+The digitizer HID interface allows setting the mouse cursor position at absolute coordinates, unlike the Pointing Device feature that applies relative displacements.
+
+To enable the digitizer interface, add the following line to your rules.mk: 
+
+```makefile
+DIGITIZER_ENABLE = yes
+```
+
+In order to change the mouse cursor position from your keymap.c file, include the digitizer header : 
+
+```c
+#include "digitizer.h"
+```
+
+This gives you access to the `digitizer` structure which members allow you to change the cursor position.
+
+The coordinates are normalized, meaning there value must be set between 0 and 1. For the `x` coordinate, the value `0` is the leftmost position, whereas the value `1` is the rightmost position.
+For the `y` coordinate, `0` is at the top and `1` at the bottom.
+
+Here is an example setting the cursor in the middle of the screen:
+
+```c
+digitizer_t digitizer;
+digitizer.x = 0.5;
+digitizer.y = 0.5;
+digitizer.tipswitch = 0;
+digitizer.inrange = 1;
+digitizer_set_report(digitizer);
+```
+
+The `tipswitch` member triggers what equates to a click when set to `1`. The `inrange` member is required for the change in coordinates to be taken. It can then be set to `0` in a new report to signal the end of the digitizer interaction, but it is not strictly required.
+
+Once all members are set to the desired value, the `status` member needs its bitmask `DZ_UPDATED` to be set so the report is sent during the next main loop iteration.

+# Key Overrides
+
+Key overrides allow you to override modifier-key combinations to send a different modifier-key combination or perform completely custom actions. Don't want `shift` + `1` to type `!` on your computer? Use a key override to make your keyboard type something different when you press `shift` + `1`. The general behavior is like this: If `modifiers w` + `key x` are pressed, replace these keys with `modifiers y` + `key z` in the keyboard report.
+
+You can use key overrides in a similar way to momentary layer/fn keys to activate custom keycodes/shortcuts, with a number of benefits: You completely keep the original use of the modifier keys, while being able to save space by removing fn keys from your keyboard. You can also easily configure _combinations of modifiers_ to trigger different actions than individual modifiers, and much more. The possibilities are quite vast and this documentation contains a few examples for inspiration throughout.
+
+##### A few more examples to get started: You could use key overrides to...
+- Send `brightness up/down` when pressing `ctrl` + `volume up/down`.
+- Send `delete` when pressing `shift` + `backspace`.
+- Create custom shortcuts or change existing ones: E.g. Send `ctrl`+`shift`+`z` when `ctrl`+`y` is pressed.
+- Run custom code when `ctrl` + `alt` + `esc` is pressed.
+
+## Setup
+
+To enable this feature, you need to add `KEY_OVERRIDE_ENABLE = yes` to your `rules.mk`.
+
+Then, in your `keymap.c` file, you'll need to define the array `key_overrides`, which defines all key overrides to be used. Each override is a value of type `key_override_t`. The array `key_overrides` is `NULL`-terminated and contains pointers to `key_override_t` values (`const key_override_t **`).
+
+## Creating Key Overrides
+
+The `key_override_t` struct has many options that allow you to precisely tune your overrides. The full reference is shown below. Instead of manually creating a `key_override_t` value, it is recommended to use these dedicated initializers:
+
+#### `ko_make_basic(modifiers, key, replacement)`
+Returns a `key_override_t`, which sends `replacement` (can be a key-modifer combination), when `key` and `modifiers` are all pressed down. This override still activates if any additional modifiers not specified in `modifiers` are also pressed down. See `ko_make_with_layers_and_negmods` to customize this behavior.
+
+#### `ko_make_with_layers(modifiers, key, replacement, layers)`
+Additionally takes a bitmask `layers` that defines on which layers the override is used.
+
+#### `ko_make_with_layers_and_negmods(modifiers, key, replacement, layers, negative_mods)`
+Additionally takes a bitmask `negative_mods` that defines which modifiers may not be pressed for this override to activate.
+
+#### `ko_make_with_layers_negmods_and_options(modifiers, key, replacement, layers, negative_mods, options)`
+Additionally takes a bitmask `options` that specifies additional options. See `ko_option_t` for available options.
+
+For more customization possibilities, you may directly create a `key_override_t`, which allows you to customize even more behavior. Read further below for details and examples.
+
+## Simple Example
+
+This shows how the mentioned example of sending `delete` when `shift` + `backspace` are pressed is realized:
+
+```c
+const key_override_t delete_key_override = ko_make_basic(MOD_MASK_SHIFT, KC_BSPACE, KC_DELETE);
+
+// This globally defines all key overrides to be used
+const key_override_t **key_overrides = (const key_override_t *[]){
+	&delete_key_override,
+	NULL // Null terminate the array of overrides!
+};
+```
+
+## Intermediate Difficulty Examples
+
+### Media Controls & Screen Brightness
+
+In this example a single key is configured to control media, volume and screen brightness by using key overrides.
+
+- The key is set to send `play/pause` in the keymap.
+
+The following key overrides will be configured:
+
+- `Ctrl` + `play/pause` will send `next track`.
+- `Ctrl` + `Shift` + `play/pause` will send `previous track`. 
+- `Alt` + `play/pause` will send `volume up`. 
+- `Alt` + `Shift` + `play/pause` will send `volume down`.
+- `Ctrl` + `Alt` + `play/pause` will send `brightness up`.
+- `Ctrl` + `Alt` + `Shift` + `play/pause` will send `brightness down`.
+
+
+```c
+const key_override_t next_track_override = 
+	ko_make_with_layers_negmods_and_options(

+### Flexible macOS-friendly Grave Escape
+The [Grave Escape feature](https://docs.qmk.fm/using-qmk/advanced-keycodes/feature_grave_esc) is limited in its configurability and has [bugs when used on macOS](https://docs.qmk.fm/using-qmk/advanced-keycodes/feature_grave_esc#caveats). Key overrides can be used to achieve a similar functionality as Grave Escape, but with more customization and without bugs on macOS.
+
+```c
+// Shift + esc = ~
+const key_override_t tilde_esc_override = ko_make_basic(MOD_MASK_SHIFT, KC_ESC, S(KC_GRAVE));
+
+// GUI + esc = `
+const key_override_t grave_esc_override = ko_make_basic(MOD_MASK_GUI, KC_ESC, KC_GRAVE);
+
+const key_override_t **key_overrides = (const key_override_t *[]){
+	&tilde_esc_override,
+	&grave_esc_override,
+	NULL
+};
+```
+
+In addition to not encountering unexpected bugs on macOS, you can also change the behavior as you wish. Instead setting `GUI` + `ESC` = `` ` `` you may change it to an arbitrary other modifier, for example `Ctrl` + `ESC` = `` ` ``.
+
+## Advanced Examples
+### Modifiers as Layer Keys
+
+Do you really need a dedicated key to toggle your fn layer? With key overrides, perhaps not. This example shows how you can configure to use `rGUI` + `rAlt` (right GUI and right alt) to access a momentary layer like an fn layer. With this you completely eliminate the need to use a dedicated layer key. Of course the choice of modifier keys can be changed as needed, `rGUI` + `rAlt` is just an example here. 
+
+```c
+// This is called when the override activates and deactivates. Enable the fn layer on activation and disable on deactivation

+| `uint8_t negative_mod_mask`                       | Which modifiers cannot be down. It must hold that `(active_modifiers & negative_mod_mask) == 0`, otherwise the key override will not be activated. An active override will be deactivated once this is no longer true.                                                                                                                                                                                                                                                                                                     |
+| `uint8_t suppressed_mods`                              | Modifiers to 'suppress' while the override is active. To suppress a modifier means that even though the modifier key is held down, the host OS sees the modifier as not pressed. Can be used to suppress the trigger modifiers, as a trivial example.                                                                                                                                                                                                                                                                                                                                            |
+| `uint16_t replacement`                                 | The complex keycode to send as replacement when this override is triggered. This can be a simple keycode, a key-modifier combination (e.g. `C(KC_A)`), or `KC_NO` (to register no replacement keycode). Use in combination with suppressed_mods to get the correct modifiers to be sent.                                                                                                                                                                                                                 |

+| `bool (*custom_action)(bool activated, void *context)` | If not NULL, this function will be called right before the replacement key is registered, along with the provided context and a flag indicating whether the override was activated or deactivated. This function allows you to run some custom actions for specific key overrides. If you return `false`, the replacement key is not registered/unregistered as it would normally. Return `true` to register and unregister the override normally. |
+| `void *context`                                        | A context that will be passed to the custom action function.                                                                                                                                                                                                                                                                                                                                                                        |

+## For Advanced Users: Inner Workings
+
+This section explains how a key override works in detail, explaining where each member of `key_override_t` comes into play. Understanding this is essential to be able to take full advantage of all the options offered by key overrides.
+
+#### Activation
+
+When the necessary keys are pressed (`trigger_mods` + `trigger`), the override is 'activated' and the replacement key is registered in the keyboard report (`replacement`), while the `trigger` key is removed from the keyboard report. The trigger modifiers may also be removed from the keyboard report upon activation of an override (`suppressed_mods`). The override will not activate if any of the `negative_modifiers` are pressed.
+
+Overrides can activate in three different cases:
+
+1. The trigger key is pressed down and necessary modifiers are already down.
+2. A necessary modifier is pressed down, while the trigger key and other necessary modifiers are already down.
+3. A negative modifier is released, while all necessary modifiers and the trigger key are already down.
+
+Use the `option` member to customize which of these events are allowed to activate your overrides (default: all three).
+
+In any case, a key override can only activate if the `trigger` key is the _last_ non-modifier key that was pressed down. This emulates the behavior of how standard OSes (macOS, Windows, Linux) handle normal key input (to understand: Hold down `a`, then also hold down `b`, then hold down `shift`; `B` will be typed but not `A`).
+
+#### Deactivation
+
+An override is 'deactivated' when one of the trigger keys (`trigger_mods`, `trigger`) is lifted, another non-modifier key is pressed down, or one of the `negative_modifiers` is pressed down. When an override deactivates, the `replacement` key is removed from the keyboard report, while the `suppressed_mods` that are still held down are re-added to the keyboard report. By default, the `trigger` key is re-added to the keyboard report if it is still held down and no other non-modifier key has been pressed since. This again emulates the behavior of how standard OSes handle normal key input (To understand: hold down `a`, then also hold down `b`, then also `shift`, then release `b`; `A` will not be typed even though you are holding the `a` and `shift` keys). Use the `option` field `ko_option_no_reregister_trigger` to prevent re-registering the trigger key in all cases.
+
+#### Key Repeat Delay
+
+A third way in which standard OS-handling of modifier-key input is emulated in key overrides is with a ['key repeat delay'](https://www.dummies.com/computers/pcs/set-your-keyboards-repeat-delay-and-repeat-rate/). To explain what this is, let's look at how normal keyboard input is handled by mainstream OSes again: If you hold down `a`, followed by `shift`, you will see the letter `a` is first typed, then for a short moment nothing is typed and then repeating `A`s are typed. Take note that, although shift is pressed down just after `a` is pressed, it takes a moment until `A` is typed. This is caused by the aforementioned key repeat delay, and it is a feature that prevents unwanted repeated characters from being typed.
+
+This applies equally to releasing a modifier: When you hold `shift`, then press `a`, the letter `A` is typed. Now if you release `shift` first, followed by `a` shortly after, you will not see the letter `a` being typed, even though for a short moment of time you were just holding down the key `a`. This is because no modified characters are typed until the key repeat delay has passed.
+
+ This exact behavior is implemented in key overrides as well: If a key override for `shift` + `a` = `b` exists, and `a` is pressed and held, followed by `shift`, you will not immediately see the letter `b` being typed. Instead, this event is deferred for a short moment, until the key repeat delay has passed, measured from the moment when the trigger key (`a`) was pressed down.
+
+The duration of the key repeat delay is controlled with the `KEY_OVERRIDE_REPEAT_DELAY` macro. Define this value in your `config.h` file to change it. It is 500ms by default.
+
+
+## Difference to Combos
+
+Note that key overrides are very different from [combos](https://docs.qmk.fm/#/feature_combo). Combos require that you press down several keys almost _at the same time_ and can work with any combination of non-modifier keys. Key overrides work like keyboard shortcuts (e.g. `ctrl` + `z`): They take combinations of _multiple_ modifiers and _one_ non-modifier key to then perform some custom action. Key overrides are implemented with much care to behave just like normal keyboard shortcuts would in regards to the order of pressed keys, timing, and interacton with other pressed keys. There are a number of optional settings that can be used to really fine-tune the behavior of each key override as well. Using key overrides also does not delay key input for regular key presses, which inherently happens in combos and may be undesirable.

The purpose of this feature is to support cosmetic use of WPM (e.g. displaying the current value on an OLED screen). This adds overhead to the split communication protocol and may negatively impact the matrix scan speed when enabled. 
+
+```c
+#define SPLIT_OLED_ENABLE
+```
+
+This enables transmitting the current OLED on/off status to the slave side of the split keyboard. The purpose of this feature is to support state (on/off state only) syncing. This adds overhead to the split communication protocol and may negatively impact the matrix scan speed when enabled. 
+
+```c
+#define SPLIT_ST7565_ENABLE
+```
+
+This enables transmitting the current ST7565 on/off status to the slave side of the split keyboard. The purpose of this feature is to support state (on/off state only) syncing. This adds overhead to the split communication protocol and may negatively impact the matrix scan speed when enabled. 
+
+### Custom data sync between sides :id=custom-data-sync
+
+QMK's split transport allows for arbitrary data transactions at both the keyboard and user levels. This is modelled on a remote procedure call, with the master invoking a function on the slave side, with the ability to send data from master to slave, process it slave side, and send data back from slave to master.
+
+To leverage this, a keyboard or user/keymap can define a comma-separated list of _transaction IDs_:
+
+```c
+// for keyboard-level data sync:
+#define SPLIT_TRANSACTION_IDS_KB KEYBOARD_SYNC_A, KEYBOARD_SYNC_B
+// or, for user:
+#define SPLIT_TRANSACTION_IDS_USER USER_SYNC_A, USER_SYNC_B, USER_SYNC_C
+```
+
+These _transaction IDs_ then need a slave-side handler function to be registered with the split transport, for example:
+
+```c
+typedef struct _master_to_slave_t {
+    int m2s_data;
+} master_to_slave_t;
+
+typedef struct _slave_to_master_t {
+    int s2m_data;
+} slave_to_master_t;
+
+void user_sync_a_slave_handler(uint8_t in_buflen, const void* in_data, uint8_t out_buflen, void* out_data) {
+    const master_to_slave_t *m2s = (const master_to_slave_t*)in_data;
+    slave_to_master_t *s2m = (slave_to_master_t*)out_data;
+    s2m->s2m_data = m2s->m2s_data + 5; // whatever comes in, add 5 so it can be sent back
+}
+
+void keyboard_post_init_user(void) {
+    transaction_register_rpc(USER_SYNC_A, user_sync_a_slave_handler);
+}
+```
+
+The master side can then invoke the slave-side handler - for normal keyboard functionality to be minimally affected, any keyboard- or user-level code attempting to sync data should be throttled:
+
+```c
+void housekeeping_task_user(void) {
+    if (is_keyboard_master()) {
+        // Interact with slave every 500ms
+        static uint32_t last_sync = 0;
+        if (timer_elapsed32(last_sync) > 500) {
+            master_to_slave_t m2s = {6};
+            slave_to_master_t s2m = {0};
+            if(transaction_rpc_exec(USER_SYNC_A, sizeof(m2s), &m2s, sizeof(s2m), &s2m)) {
+                last_sync = timer_read32();
+                dprintf("Slave value: %d\n", s2m.s2m_data); // this will now be 11, as the slave adds 5
+            } else {
+                dprint("Slave sync failed!\n");
+            }
+        }
+    }
+}
+```
+
+!> It is recommended that any data sync between halves happens during the master side's _housekeeping task_. This ensures timely retries should failures occur.
+
+If only one-way data transfer is needed, helper methods are provided:
+
+```c
+bool transaction_rpc_exec(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+bool transaction_rpc_send(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer);
+bool transaction_rpc_recv(int8_t transaction_id, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+```
+
+By default, the inbound and outbound data is limited to a maximum of 32 bytes each. The sizes can be altered if required:
+
+```c
+// Master to slave:
+#define RPC_M2S_BUFFER_SIZE 48
+// Slave to master:
+#define RPC_S2M_BUFFER_SIZE 48
+```

+
+## Usage
+
+To enable the feature, there are three steps. First, when compiling your keyboard, you'll need to add the following to your `rules.mk`:
+
+```make
+ST7565_ENABLE = yes
+```
+
+Then in your `keymap.c` file, implement the ST7565 task call. This example assumes your keymap has three layers named `_QWERTY`, `_FN` and `_ADJ`:
+
+```c
+#ifdef ST7565_ENABLE
+void st7565_task_user(void) {
+    // Host Keyboard Layer Status
+    st7565_write_P(PSTR("Layer: "), false);
+
+    switch (get_highest_layer(layer_state)) {
+        case _QWERTY:
+            st7565_write_P(PSTR("Default\n"), false);
+            break;
+        case _FN:
+            st7565_write_P(PSTR("FN\n"), false);
+            break;
+        case _ADJ:
+            st7565_write_P(PSTR("ADJ\n"), false);
+            break;
+        default:
+            // Or use the write_ln shortcut over adding '\n' to the end of your string
+            st7565_write_ln_P(PSTR("Undefined"), false);
+    }
+
+    // Host Keyboard LED Status
+    led_t led_state = host_keyboard_led_state();
+    st7565_write_P(led_state.num_lock ? PSTR("NUM ") : PSTR("    "), false);
+    st7565_write_P(led_state.caps_lock ? PSTR("CAP ") : PSTR("    "), false);
+    st7565_write_P(led_state.scroll_lock ? PSTR("SCR ") : PSTR("    "), false);
+}
+#endif
+```
+
+## Logo Example
+
+In the default font, certain ranges of characters are reserved for a QMK logo. To render this logo to the screen, use the following code example:
+
+```c
+static void render_logo(void) {
+    static const char PROGMEM qmk_logo[] = {
+        0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x86, 0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94,
+        0xA0, 0xA1, 0xA2, 0xA3, 0xA4, 0xA5, 0xA6, 0xA7, 0xA8, 0xA9, 0xAA, 0xAB, 0xAC, 0xAD, 0xAE, 0xAF, 0xB0, 0xB1, 0xB2, 0xB3, 0xB4,
+        0xC0, 0xC1, 0xC2, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8, 0xC9, 0xCA, 0xCB, 0xCC, 0xCD, 0xCE, 0xCF, 0xD0, 0xD1, 0xD2, 0xD3, 0xD4, 0x00
+    };
+
+    st7565_write_P(qmk_logo, false);
+}
+```
+
+## Buffer Read Example
+For some purposes, you may need to read the current state of the display buffer. The `st7565_read_raw` function can be used to safely read bytes from the buffer.
+
+In this example, calling `fade_display` in the `st7565_task_user` function will slowly fade away whatever is on the screen by turning random pixels off over time.
+```c
+//Setup some mask which can be or'd with bytes to turn off pixels
+const uint8_t single_bit_masks[8] = {127, 191, 223, 239, 247, 251, 253, 254};
+
+static void fade_display(void) {
+    //Define the reader structure
+    display_buffer_reader_t reader;
+    uint8_t buff_char;
+    if (random() % 30 == 0) {
+        srand(timer_read());
+        // Fetch a pointer for the buffer byte at index 0. The return structure
+        // will have the pointer and the number of bytes remaining from this
+        // index position if we want to perform a sequential read by
+        // incrementing the buffer pointer
+        reader = st7565_read_raw(0);
+        //Loop over the remaining buffer and erase pixels as we go
+        for (uint16_t i = 0; i < reader.remaining_element_count; i++) {
+            //Get the actual byte in the buffer by dereferencing the pointer
+            buff_char = *reader.current_element;
+            if (buff_char != 0) {
+                st7565_write_raw_byte(buff_char & single_bit_masks[rand() % 8], i);
+            }
+            //increment the pointer to fetch a new byte during the next loop
+            reader.current_element++;
+        }
+    }
+}
+```
+
+## Other Examples
+
+In split keyboards, it is very common to have two displays that each render different content and are oriented or flipped differently. You can do this by switching which content to render by using the return value from `is_keyboard_master()` or `is_keyboard_left()` found in `split_util.h`, e.g:
+
+```c
+#ifdef ST7565_ENABLE
+display_rotation_t st7565_init_user(display_rotation_t rotation) {
+    if (!is_keyboard_master()) {
+        return DISPLAY_ROTATION_180;  // flips the display 180 degrees if offhand
+    }
+
+    return rotation;
+}
+
+void st7565_task_user(void) {
+    if (is_keyboard_master()) {
+        render_status();  // Renders the current keyboard state (layer, lock, caps, scroll, etc)
+    } else {
+        render_logo();  // Renders a static logo
+    }
+}
+#endif
+```

+Our next stop is `tap_dance_task()`. This handles the timeout of tap-dance keys.
 
 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.

+### QMK HID
+
+QMK maintains [a fork of the LUFA HID bootloader](https://github.com/qmk/lufa/tree/master/Bootloaders/HID), which uses a USB HID Endpoint for flashing in the way that the PJRC's Teensy Loader flasher and HalfKay bootloader work. Additionally, it performs a simple matrix scan for exiting the bootloader and returning to the application, as well as flashing an LED/making a ticking noise with a speaker when things are happening.
+
+To ensure compatibility with the QMK HID bootloader, make sure this block is present in your `rules.mk`:
+
+```make
+# Bootloader selection
+BOOTLOADER = qmk-hid
+```
+
+To enable the additional features, add the following defines to your `config.h`:
+
+```c
+#define QMK_ESC_OUTPUT F1  // COL pin if COL2ROW
+#define QMK_ESC_INPUT  D5  // ROW pin if COL2ROW
+// Optional:
+//#define QMK_LED E6
+//#define QMK_SPEAKER C6
+```
+
+Currently we do not recommend making `QMK_ESC` the same key as the one designated for [Bootmagic Lite](feature_bootmagic.md), as holding it down will cause the MCU to loop back and forth between entering and exiting the bootloader.
+
+The manufacturer and product strings are automatically pulled from `config.h`, with " Bootloader" appended to the product string.
+
+To generate this bootloader, use the `bootloader` target, eg. `make planck/rev4:default:bootloader`. To generate a production-ready .hex file (combining QMK and the bootloader), use the `production` target, eg. `make planck/rev4:default:production`.

+  * Currently, you need to either use the [Python script](https://github.com/qmk/lufa/tree/master/Bootloaders/HID/HostLoaderApp_python), or compile [`hid_bootloader_cli`](https://github.com/qmk/lufa/tree/master/Bootloaders/HID/HostLoaderApp), from the LUFA repo. Homebrew may (will) have support for this directly (via `brew install qmk/qmk/hid_bootloader_cli`).

Keep in mind that users who want this functionality can enable it in their personal keymaps without affecting all the novice users who may be using your keyboard as their first programmable board.
+[Magic Keycodes](keycodes_magic.md) and [Command](feature_command.md) are two related features that allow a user to control their keyboard in non-obvious ways.

Keep in mind that users who want this functionality can enable it in their personal keymaps without affecting all the novice users who may be using your keyboard as their first programmable board.
 
 By far the most common problem new users encounter is accidentally triggering Bootmagic while they're plugging in their keyboard. They're holding the keyboard by the bottom, unknowingly pressing in alt and spacebar, and then they find that these keys have been swapped on them. We recommend leaving this feature disabled by default, but if you do turn it on consider setting `BOOTMAGIC_KEY_SALT` to a key that is hard to press while plugging your keyboard in.

+## Tap-Or-Hold Decision Modes
 
-## Permissive Hold
+The code which decides between the tap and hold actions of dual-role keys supports three different modes, in increasing order of preference for the hold action:
 
-As of [PR#1359](https://github.com/qmk/qmk_firmware/pull/1359/), there is a new `config.h` option:
+1. The default mode selects the hold action only if the dual-role key is held down longer than the tapping term.  In this mode pressing other keys while the dual-role key is held down does not influence the tap-or-hold decision.
+
+2. The “permissive hold” mode, in addition to the default behavior, immediately selects the hold action when another key is tapped (pressed and then released) while the dual-role key is held down, even if this happens earlier than the tapping term.  If another key is just pressed, but then the dual-role key is released before that other key (and earlier than the tapping term), this mode will still select the tap action.
+
+3. The “hold on other key press” mode, in addition to the default behavior, immediately selects the hold action when another key is pressed while the dual-role key is held down, even if this happens earlier than the tapping term.
+
+Note that until the tap-or-hold decision completes (which happens when either the dual-role key is released, or the tapping term has expired, or the extra condition for the selected decision mode is satisfied), key events are delayed and not transmitted to the host immediately.  The default mode gives the most delay (if the dual-role key is held down, this mode always waits for the whole tapping term), and the other modes may give less delay when other keys are pressed, because the hold action may be selected earlier.
+
+### Permissive Hold
+
+The “permissive hold” mode can be enabled for all dual-role keys by adding the corresponding option to `config.h`:
 
 ```c
 #define PERMISSIVE_HOLD
 ```
 
-This makes tap and hold keys (like Mod Tap) work better for fast typists, or for high `TAPPING_TERM` settings.
+This makes tap and hold keys (like Layer Tap) work better for fast typists, or for high `TAPPING_TERM` settings.
 
-If you press a Mod Tap key, tap another key (press and release) and then release the Mod Tap key, all within the tapping term, it will output the tapping function for both keys.
+If you press a dual-role key, tap another key (press and release) and then release the dual-role key, all within the tapping term, by default the dual-role key will perform its tap action.  If the `PERMISSIVE_HOLD` option is enabled, the dual-role key will perform its hold action instead.
 
-For Instance:
+An example of a sequence which is affected by the “permissive hold” mode:
 
-- `SFT_T(KC_A)` Down
+- `LT(2, KC_A)` Down
-- `KC_X` Down
+- `KC_L` Down (the `L` key is also mapped to `KC_RGHT` on layer 2)
-- `KC_X` Up
+- `KC_L` Up
-- `SFT_T(KC_A)` Up
+- `LT(2, KC_A)` Up
 
-Normally, if you do all this within the `TAPPING_TERM` (default: 200ms) this will be registered as `ax` by the firmware and host system. With permissive hold enabled, this modifies how this is handled by considering the Mod Tap keys as a Mod if another key is tapped, and would registered as `X` (`SHIFT`+`x`).
+Normally, if you do all this within the `TAPPING_TERM` (default: 200ms), this will be registered as `al` by the firmware and host system.  With the `PERMISSIVE_HOLD` option enabled, the Layer Tap key is considered as a layer switch if another key is tapped, and the above sequence would be registered as `KC_RGHT` (the mapping of `L` on layer 2).
 
-?> If you have `Ignore Mod Tap Interrupt` enabled, as well, this will modify how both work. The regular key has the modifier added if the first key is released first or if both keys are held longer than the `TAPPING_TERM`.
+However, this slightly different sequence will not be affected by the “permissive hold” mode:
+
+- `LT(2, KC_A)` Down
+- `KC_L` Down (the `L` key is also mapped to `KC_RGHT` on layer 2)
+- `LT(2, KC_A)` Up
+- `KC_L` Up
+
+In the sequence above the dual-role key is released before the other key is released, and if that happens within the tapping term, the “permissive hold” mode will still choose the tap action for the dual-role key, and the sequence will be registered as `al` by the host.
+
+?> The `PERMISSIVE_HOLD` option also affects Mod Tap keys, but this may not be noticeable if you do not also enable the `IGNORE_MOD_TAP_INTERRUPT` option for those keys, because the default handler for Mod Tap keys also considers both the “nested press” and “rolling press” sequences like shown above as a modifier hold, not the tap action.  If you do not enable `IGNORE_MOD_TAP_INTERRUPT`, the effect of `PERMISSIVE_HOLD` on Mod Tap keys would be limited to reducing the delay before the key events are made visible to the host.

-Similar to Permissive Hold, this alters how the firmware processes inputs for fast typists. If you press a Mod Tap key, press another key, release the Mod Tap key, and then release the normal key, it would normally output the Mod plus the normal key, even if pressed within the `TAPPING_TERM`. This may not be desirable for rolling combo keys, or for fast typists who have a Mod Tap on a frequently used key (`RCTL_T(KC_QUOT)`, for example).
+?> This option affects only the Mod Tap keys; it does not affect other dual-role keys such as Layer Tap.
 
-Setting `Ignore Mod Tap Interrupt` requires  holding both keys for the `TAPPING_TERM` to trigger the hold function (the mod).
+By default the tap-or-hold decision for Mod Tap keys strongly prefers the hold action.  If you press a Mod Tap key, then press another key while still holding the Mod Tap key down, the Mod Tap press will be handled as a modifier hold even if the Mod Tap key is then released within the tapping term, and irrespective of the order in which those keys are released.  Using options such as `PERMISSIVE_HOLD` or `HOLD_ON_OTHER_KEY_PRESS` will not affect the functionality of Mod Tap keys in a major way (these options would still affect the delay until the common code for dual-role keys finishes its tap-or-hold decision, but then the special code for Mod Tap keys will override the result of that decision and choose the hold action if another key was pressed).  In fact, by default the tap-or-hold decision for Mod Tap keys is done in the same way as if the `HOLD_ON_OTHER_KEY_PRESS` option was enabled, but without the decreased delay provided by `HOLD_ON_OTHER_KEY_PRESS`.
 
-For Instance:
+If the `IGNORE_MOD_TAP_INTERRUPT` option is enabled, Mod Tap keys are no longer treated as a special case, and their behavior will match the behavior of other dual-role keys such as Layer Tap.  Then the behavior of Mod Tap keys can be further tuned using other options such as `PERMISSIVE_HOLD` or `HOLD_ON_OTHER_KEY_PRESS`.
+
+An example of a sequence which will be affected by the `IGNORE_MOD_TAP_INTERRUPT` option (assuming that options like `PERMISSIVE_HOLD` or `HOLD_ON_OTHER_KEY_PRESS` are not enabled):
 
 - `SFT_T(KC_A)` Down
 - `KC_X` Down
 - `SFT_T(KC_A)` Up
 - `KC_X` Up
 
-Normally, this would send a capital `X` (`SHIFT`+`x`), or, Mod + key. With `Ignore Mod Tap Interrupt` enabled, holding both keys are required for the `TAPPING_TERM` to register the hold action. A quick tap will output `ax` in this case, while a hold on both will still output capital `X` (`SHIFT`+`x`).
+Normally, this would send a capital `X` (`SHIFT`+`x`), even if the sequence is performed faster than the `TAPPING_TERM`.  However, if the `IGNORE_MOD_TAP_INTERRUPT` option is enabled, the `SFT_T(KC_A)` key must be held longer than the `TAPPING_TERM` to register the hold action.  A quick tap will output `ax` in this case, while a hold will still output a capital `X` (`SHIFT`+`x`).
 
-
+However, if the `HOLD_ON_OTHER_KEY_PRESS` option is enabled in addition to `IGNORE_MOD_TAP_INTERRUPT`, the above sequence will again send a capital `X` (`SHIFT`+`x`) even if performed faster that the `TAPPING_TERM`.  The difference from the default configuration is that by default the host will receive the key events only after the `SFT_T(KC_A)` key is released, but with the `HOLD_ON_OTHER_KEY_PRESS` option the host will start receiving key events when the `KC_X` key is pressed.
