title: Shortcut alt+enter is not working in Android Studio
body: <p><kbd>alt</kbd> +  <kbd>enter</kbd>for importing was work normally maybe until I updated Android Studio,
  my version now is<code>2.3.3</code></p>
  
  <p>as this screenshot, I can't press <kbd>alt</kbd> +  <kbd>enter</kbd> at all, knowing that I have tested them on other programs and they are working normally
