 * **Global override** [background and foreground] ⇒ This style has a series of checkboxes, which allow you to choose which attributes of the override-style will apply to everything; any that are checked will override even the per-language settings; any that are not checked will not use the global-override settings for that attribute.
    - Global override takes precedence over any other color or font defined elsewhere, and will mask any per-language settings.
    - Unless you want to turn off all syntax highlighting for all the programming languages, you likely don't want to use the `Global override` settings.

    - Starting in v8.7.1, there is a `What is Global override?` link which you can hover over to find out more about the global overrides; and new installations and new portable copies will have **Global override** at the _end_ of the list of **Global Styles** instead of the beginning, to better emphasize that **Global override** is more drastic than you usually need.

        - In such a case, or even if you are in an older version of Notepad++, you can edit [`%AppData%\Notepad++\stylers.xml` (or your active theme file)](../config-files/#highlighting-schemes-stylersxml) following the advice for [editing configuration files](../config-files/#editing-configuration-files), and move the `<WidgetStyle name="Global override" ... />` element from the top of the `<GlobalStyles>` section to the end of that section; after saving, exiting Notepad++, and restarting the app, **Global override** will be moved to the end of the list.
