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. You should not use this module until the ready event of app module gets emitted.

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();
});
