About this plugin
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
post_type=download', 'cap' => 'manage_shop_settings' ) );
Add a shortcut for the Jetpack Dashboard
page=jetpack', 'cap' => 'manage_options', ) );
