title: Electron app: can't find where keyboard shortcut is registered
body: <p>I'm new to electron apps, and I'm attempting to modify an open source electron app.</p>
  <p>Here is the repo for the app I want to modify:</p>
  <p><a href="https://github.com/microsoft/VoTT" rel="nofollow noreferrer">https://github.com/microsoft/VoTT</a></p>
  <p>Specifically, I want to change what happens when Ctrl(+Alt or Shift)+Arrow key is pressed. I've found where most keyboard shortcuts are registered, but not this one. The app doesn't appear to use global shortcuts.</p>
  <p>Are there any other methods of registering a shortcut I should be looking for?</p>
  <p>Thanks in advance.</p>
