## 模块简介
绑定快捷键 API可以自定义项目快捷键使用。
## 方法签名functions
### bind
绑定快捷键
**类型定义**
```typescript
function bind(
combos: string[] | string,
callback: (e: KeyboardEvent, combo?: string) => any | false,
action?: string
): () => void;
```
**示例**
```typescript
hotkey.bind('command+s', (e) => {
e.preventDefault();
// command+s 快捷键按下时需要执行的逻辑
});
```
## 使用示例
### 基础示例
```typescript
hotkey.bind('command+s', (e) => {
e.preventDefault();
// command+s 快捷键按下时需要执行的逻辑
});
```
### 同时绑定多个快捷键
```typescript
hotkey.bind(['command+s', 'command+c'], (e) => {
e.preventDefault();
// command+s 或者 command+c 快捷键按下时需要执行的逻辑
});
```
### 保存快捷键配置
```typescript
import {
hotkey,
} from '@alilc/lowcode-engine';
function saveSchema(schema) {
// 保存 schema 相关操作
}
const saveSampleHotKey = (ctx: ILowCodePluginContext) => {
return {
name: 'saveSample',
async init() {
hotkey.bind('command+s', (e) => {
e.preventDefault();
saveSchema();
});
},
};
}
saveSampleHotKey.pluginName = 'saveSampleHotKey';
plugins.register(saveSampleHotKey);
```
