+## Translate
+**窗口风格默认为:** `cursor`
+- 动作(action):
+    - `vsplit`         水平分屏
+    - `split`          垂直分屏
+    - `float`          窗口样式又`cursor` 变为`float`
+    - `online_query`   使用在线引擎重新进行查询
+    - `history_insert` 将此次查询的单词记录到历史记录  
+    - `next`           展示下一个引擎的查询结果(如果默认设置了多个引擎)
+    - `prev`           展示上一个查询结果
+    > 如果没有设置自动保存历史的话
+
+    - `history`        查看历史查询的记录
+
+- `online_query`:
+    - `local_add`    将此次查询的结果添加到本地数据库  
+    > **如果本地已经存在该单词，会询问是否需要覆盖掉相同的字段**
+
+    - `local_update` 和*local_add* 类似, 但是不会询问是否覆盖
+    - `diff`         对比本地查询结果和此次在线查询的区别
+
+>  **注意**: 动作是任何窗口通用的  
+## TranslateInput
+**窗口风格默认为:** `float`
+- 自行得到要查询的单词
+
+- TODO: 
+    - fuzzy match
+
+## TranslateHistory
+**窗口风格默认为:** `float`
+- 查看历史查询
+
+---
+## 自定义
+
+### 可选项说明
+- 查询方式(method): `string`
+    - `input` 自行输入需要查询的单词
+    - `last`  显示上一次查询的结果
+    - `history`
+
+- 查询引擎(engine): `string | table`
+    - `offline` 离线的数据库
+    - `youcao` 有道api
+    - `baidu` 百度api
+    - `google` 谷歌api
+    - `bing` 必应api
+    - `iciba` 金山词霸api
+    - `xunfei` 讯飞api
+
+- 窗口风格(win): `string | table`
+    - 样式(style): 
+        - `cursor` 在光标附近弹出
+        - `float` 悬浮窗口
+        - `split` 在上方或者下方分屏
+        - `vsplit` 在左边或者右边分屏
+
+    - 高度(height):
+        - `value > 1` 最大高度
+        - `0 <= value <= 1` 相对高度
+        - `0 < value` 无限制
+
+    - 宽度(width):
+        > 和`高度(height)`相同
+### 示例
