## 3. Layer ## 4. Layer switching Example
Layer is key-action map to assign action to every physical key. You can define multiple layers in keymap and make layers active out of keymap during operation at will. There are some ways to switch layer with 'Layer' actions.
First layer is indexed by `0` which usually become `default layer` and active in initial state.
You can define **16 layers** at most in each keymaps and overlays.

`--- default_layer = 0
you can define a layer with placing keycode symbols separated with `comma` in `KEYMAP`, which is formed with resemblance to physical keyboard layout so as you can easily put keycode on place you want to map. ***You can define most of keys with just using keycodes*** except for `Fn` key serving special actions.
### 3.0 Transparency
With KC_TRNS you can define transparent key which itself doesn't have action but refer to lower valid layer. Transparent key is useful when you want to change part of layout not over all.
## 4. Layer switching
You can have some ways to switch layer with these actions.
There are two kind of layer switch action `Layer Set` and `Layer Bit` and two type of switching behaviour **Momentary** and **Toggle**.
### 4.1 Momentary switching ### 4.1 Momentary switching
Momentary switching changes layer only while holding Fn key. Momentary switching changes layer only while holding Fn key.
#### 4.1.1 Momentary Set This action makes 'Layer 1' active(valid) on key press event and inactive on release event. Namely you can overlay a layer on base layer temporarily with this.
This action makes `Layer 1` active on key press event and inactive on release event..
ACTION_KEYMAP_MOMENTARY(1) ACTION_KEYMAP_MOMENTARY(1)
It switches to destination layer immediately when key is pressed, after that actions on keymap of destination layer is perfomed. ***Thus you shall need to place action to come back on destination layer***, or you will be stuck in destination layer without way to get back. To get back to `default layer` you can use this action. After switch actions of destination layer are perfomed.
***Thus you shall need to place action to come back on destination layer***, or you will be stuck in destination layer without way to get back. Usually you need to palce same action or 'KC_TRNS` on destination layer to get back.
ACTION_LAYER_DEFAULT
#### 4.1.2 Momentary Bit
This `Layer Bit` action performs XOR `1` with `current layer` on both press and release event. If you are on `Layer 0` now next layer to switch will be `Layer 1`. To come back to previous layer you need to place same action on destination layer.
ACTION_LAYER_BIT(1)
### 4.2 Toggle switching ### 4.2 Toggle switching
Toggle switching changes layer after press then release. You keep being on the layer until you press key to return. Toggle switching changes layer after press then release. With this you can keep staying on the layer until you press the key again to return.
#### 4.2.1 Toggle Set This is toggle action of 'Layer 2'.
This `Layer Set Toggle` action is to set `Layer 1` to `current layer` on release and do none on press.
ACTION_LAYER_SET_TOGGLE(1) ACTION_KEYMAP_TOGGLE(2)
To get back to `default layer` you can use this action.
ACTION_LAYER_DEFAULT
#### 4.2.2 Toggle Bit
This `Layer Bit Toggle` action is to XOR `1` with `current layer` on release and do none on press. If you are on `Layer 2` you'll switch to `Layer 3` on press. To come back to previous layer you need to place same action on destination layer.
ACTION_LAYER_BIT_TOGGLE(1)
### 4.3 Momentary switching with Tap key ### 4.3 Momentary switching with Tap key
These actions switch to layer only while holding `Fn` key and register key on tap. **Tap** means to press and release key quickly. These actions switch layer only while holding `Fn` key and register key on tap. **Tap** means to press and release key quickly.
ACTION_KEYMAP_TAP_KEY(2, KC_SCLN)
With this you can place layer switching function on normal key like ';' without losing its original key register function.
ACTION_LAYER_SET_TAP_KEY(2, KC_SCLN)
ACTION_LAYER_SET_BIT_KEY(2, KC_SCLN)
With these you can place layer switching function on normal alphabet key like `;` without losing its original register function.
### 4.4 Momentary switching with Tap Toggle ### 4.4 Momentary switching with Tap Toggle
This changes layer only while holding `Fn` key and toggle layer after several taps. **Tap** means to press and release key quickly. This switches layer only while holding `Fn` key and toggle layer after several taps. **Tap** means to press and release key quickly.
ACTION_LAYER_SET_TAP_TOGGLE(layer) ACTION_KEYMAP_TAP_TOGGLE(1)
ACTION_LAYER_BIT_TAP_TOGGLE(layer)
Number of taps can be defined with `TAPPING_TOGGLE` in `config.h`, `5` by default. Number of taps can be defined with `TAPPING_TOGGLE` in `config.h`, `5` by default.
## Tapping ## Tapping
Tapping is to press and release key quickly. Tapping speed is determined with setting of `TAPPING_TERM`, which can be defined in `config.h`, 200ms by default.
### Tap Key ### Tap Key
This is feature to assign normal key action and modifier including `Fn` to just one physical key. This is a kind of [Dual role modifier][dual_role]. It works as modifier or `Fn` when holding a key but registers normal key when tapping.
Action for modifier with tap key.
ACTION_LMODS_TAP_KEY(mods, key)
Action for `Fn` with tap key.
ACTION_KEYMAP_TAP_KEY(layer, key)
[dual_role]: http://en.wikipedia.org/wiki/Modifier_key#Dual-role_modifier_keys
### Tap Toggle
This is feature to assign both toggle layer and momentary switch layer action to just one physical key. It works as mementary switch when holding a key but toggle switch when tapping.
ACTION_KEYMAP_TAP_TOGGLE(layer)
### One Shot Modifier ### One Shot Modifier
This adds oneshot feature to modifier key. 'One Shot Modifier' is one time modifier which has effect only on following one alpha key.
It works as normal modifier key when holding but oneshot modifier when tapping.
ACTION_LMODS_ONESHOT(mods)
Say you want to type 'The', you have to push and hold Shift before type 't' then release Shift before type 'h' and 'e' or you'll get 'THe'. With One Shot Modifier you can tap Shift then type 't', 'h' and 'e' normally, you don't need to holding Shift key properly here.
