Action is a **16bit code** and defines function to perform on events of a key like press, release, holding and tapping. Most of keys just register 8bit scancode to host, but to support other complex features needs 16bit extended action codes internally. However, using 16bit action codes in keymap results in double size in memory compared to using jsut keycodes. To avoid this waste 8bit keycodes are used in `KEYMAP()` instead of action codes. ***You can just use keycodes of `Normal key`, `Modifier`, `Mousekey` and `System & Media key` in keymap*** to indicate corresponding actions instead of using action codes. While ***to use other special actions you should use keycode of `Fn` key defined in `fn_actions[]`.*** -### 2.1 Key action +### 2.1 Key Action This is a simple action that registers scancodes(HID usage in fact) to host on press event of key and unregister on release. +#### Parameters ++ **mods**: { ` MOD_LCTL`, ` MOD_LSFT`, ` MOD_LALT`, ` MOD_LGUI`, + ` MOD_RCTL`, ` MOD_RSFT`, ` MOD_RALT`, ` MOD_RGUI` } ++ **key**: keycode + + #### 2.1.1 Normal key and Modifier ***This action usually won't be used expressly in keymap*** because you can just use keycodes in `KEYMAP()` instead. @@ -226,67 +232,72 @@ This action is comprised of strokes of modifiers and a key. `Macro` action is ne Say you want to assign a key to `Shift + 1` to get charactor *'!'* or `Alt + Tab` to switch application windows. - ACTION_MOD_KEY(KC_LSFT, KC_1) - ACTION_MOD_KEY(KC_LALT, KC_TAB) + ACTION_MODS_KEY(MOD_LSFT, KC_1) + ACTION_MODS_KEY(MOD_LALT, KC_TAB) -Or `Alt,Shift + Tab` can be defined. `ACTION_LMODS_KEY()` requires **4-bit modifier state** and a **keycode** as arguments.
