How to find the List Screen ID or Key
The "List Screen ID" and "List Screen Key" can be found by opening the screen options in the top-right corner of the admin columns settings page. Enable the "List screen ID/Key" by clicking the checkbox next to it. The list screen ID (or Key) will now be visible in the right sidebar.
What is the List Screen
The `List Screen` is our representation of the WordPress List table including filters and screen options. For example: The `Page List Screen` is the `WordPress Pages List Table`. We use the AC/ListScreen object in our code to retrieve its properties/features and store its columns and settings.
What is the List Screen ID
The `ID` is a unique identifier that is assigned when the List Screen has been stored in the database. e.g. 5eeca96a61826.
The method AC\ListScreen::get_layout_id() will return the list screen ID.
What is the List Screen Key
The `Key` is a hard-coded identifier for each type of list screen. There are multiple types of list screens, such as 'Posts', 'Pages', 'Users' or 'Media.
Examples
| List Screen Label | Key | Example |
| Posts | $post_type |

| Pages | $post_type |

| Users | wp-users |

| Comments | wp-comments |
wp-comments |
| Categories | wp-taxonomy_{$term} |

| Tags | wp-taxonomy_{$term} |

The method AC\ListScreen::get_key() will return the list screen Key.
The $list_screen_id or $list_screen_key is useful when you are using our actions and filters and you need to target a specific List Screen.
Database
