 Many of existent projects offer keymap framework to define your own keymap easily. The following will explain how you can define keymap using this framework.
  Instead, you can also implement your own `keymap_get_action()` to return action code for each key if you want.

 ### 1. Keycode
-See `common/keycode.h`. Keycode is 8bit internal code to inidicate action performed on key in keymap. Keycode has `KC_` prefixed symbol respectively. Most of keycodes like 'KC_A' have simple action register key on press and unregister on release, on the other some of keycodes has some special actions like Fn keys, Media contorl keys, System control keys and Mouse keys.

  ***In `KEYMAP` definition you need to omit prefix part `KC_` of keycode to keep keymap compact.*** For example, just use `A` instead you place `KC_A` in `KEYMAP`. Some keycodes has 4-letter short name in addition to descriptive name, you'll prefer short one in `KEYMAP`.
 
- **`KC_NO`** indicates the key has no keycode to transmit.

+
+#### 1.3 Fn key
  **`KC_FNnn`** are `Fn` keys which not given any action at the beginning unlike most of keycodes has its own action. To use these keys in `KEYMAP` you need to assign action you want at first. Action of `Fn` is defined in `fn_actions[]` and index of the array is identical with number part of `KC_FNnn`. Thus `KC_FN0` designates action defined in first element of the array. ***32 `Fn` keys can be defined at most.***

 ### 2. Action
 See `common/action.h`. Action is a 16bit code and defines function to perform on events of a key like press, release, hold and tap. You can define various actions to use various action codes.
 
-Most of keys just register 8bit keycode as HID usage(or scan code) to host, but to support other complex functions needs 16bit extended action codes internally. But using 16bit action codes with keymap results in double size in memory against keycodes. To avoid this waste 8bit keycodes are used in `KEYMAP` to define instead of action codes. ***Keycodes can be considered as subset of action codes.*** Like `KC_A`(0x04) is equal to a `Key` action(0x0004) that transmit keycode of `A`.

+
+This C function is called every time key is operated, argument `id` selects action to be performed and `opt` can be used for option. Functon `id` can be 0-255 and `opt` can be 0-15.
+
+ `keyrecord_t` is comprised of key event and tap count. `keyevent_t` indicates which and when key is pressed or released. From `tap_count` you can know tap state, 0 means no tap. These information will be used in user function to decide how action of key is performed.
