# global-shortcut

The `global-shortcut` module can register/unregister a global keyboard shortcut
in operating system, so that you can customize the operations for various shortcuts.
Note that the shortcut is global, even if the app does not get focused, it will still work.

```javascript
var globalShortcut = require('global-shortcut');

// Register a 'ctrl+x' shortcut listener.
var ret = globalShortcut.register('ctrl+x', function() { console.log('ctrl+x is pressed'); })
if (!ret)
  console.log('registerion fails');

// Check whether a shortcut is registered.
console.log(globalShortcut.isRegistered('ctrl+x'));

// Unregister a shortcut.
globalShortcut.unregister('ctrl+x');

// Unregister all shortcuts.
globalShortcut.unregisterAll();
```
