Usher brings Gmail-like keyboard shortcuts for navigating around the various core pages of the WordPress admin.
Additionally, it includes a robust API for registering new global and screen-specific keyboard shortcuts.
To register new shortcuts, use the Usher\register_shortcut() function. For example:
Add a shortcut for the EDD Dashboard
<pre><code>Usher\register_shortcut( 'g d', array(
 'label' => __( 'Navigate to the EDD dashboard', 'textdomain' ),
 'url' => 'edit.php?post_type=download',
 'cap' => 'manage_shop_settings'
) );
</code></pre>
Add a shortcut for the Jetpack Dashboard
<pre><code>Usher\register_shortcut( 'g j', array(
 'label' => __( 'Navigate to the Jetpack dashboard', 'textdomain' ),
 'url' => 'admin.php?page=jetpack',
 'cap' => 'manage_options',
) );
</code></pre>
