ReSharper | Options | Code Editing | XML | Editor
This page allows you to adjust ReSharper's XML features in the editor. These are language-specific settings that complement the main set of editor features.
|Synchronous changing of matching tag||If this check box is selected, ReSharper simultaneously changes the closing tag when you are editing the opening tag of an element and vice versa.|
ReSharper's settings are saved in settings layers that enable you to have different settings for different solutions as well as to share your settings with your team. To learn more, study the Managing and Sharing Options section.
