Filters the title tag content for an admin page.

Filters the CSS classes for the body tag in the admin. This filter differs from the {@see 'post_class'} and {@see 'body_class'} filters in two important ways: 1. `$classes` is a space-separated string of class names instead of an array. 2. Not all core admin classes are filterable, notably: wp-admin, wp-core-ui, and no-js cannot be removed.

This action is documented in wp-admin/network/site-themes.php

Filters a specific, non-default, site-updated message in the Network admin. The dynamic portion of the hook name, `$action`, refers to the non-default site update action.

Filters available network-wide administration menu options. Options returned to this filter are output as individual checkboxes that, when selected, enable site administrator access to the specified administration menu in certain contexts. Adding options for specific menus here hinges on the appropriate checks and capabilities being in place in the site dashboard on the other side. For instance, when the single default option, 'plugins' is enabled, site administrators are granted access to the Plugins screen in their individual sites' dashboards.
