# global-shortcut

The `global-shortcut` module can register/unregister a global keyboard shortcut
with the operating system, so that you can customize the operations for various shortcuts.
Note that the shortcut is global; it will work even if the app does not have the keyboard focus.
You should not use this module until the `ready` event of the app module is emitted.

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

app.on('ready', function() {
  // Register a 'ctrl+x' shortcut listener.
  var ret = globalShortcut.register('ctrl+x', function() {
    console.log('ctrl+x is pressed');
  })

  if (!ret) {
    console.log('registration failed');
  }

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

app.on('will-quit', function() {
  // Unregister a shortcut.
  globalShortcut.unregister('ctrl+x');

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