<p>

In Android N, the user can press "Alt + /" to trigger a <em>Keyboard Shortcuts</em>

screen that displays all shortcuts available both from the system and from

the app in focus. These are retrieved automatically from the app’s menu if

available, but developers can provide their own fine-tuned shortcuts lists

for the screen. You can do this by overriding the new

<code>Activity.onProvideKeyboardShortcuts()</code> method, described in the downloadable

<a href="{@docRoot}preview/setup-sdk.html#docs-dl">API Reference</a>.
