Highlight Component Occurrences

When a component (for example variable or named template) is found at current cursor
      position, Oxygen XML Editor performs a search over the entire document to find the
      component declaration and all its references. When found, they are highlighted both in the
      document and in the stripe bar, at the right side of the document.Note: Oxygen XML Editor
        also supports occurrences highlight for template modes.
Customizable colors are used:
      one for the component definition and another one for component references. Occurrences are
      displayed until another component is selected and a new search is performed. All occurrences
      are removed when you start to edit the document. 

This feature is enabled by default. To configure it, open the Preferences dialog box (Options > Preferences) and go to Editor > Mark Occurrences. A search can also be triggered with the Search > Search Occurrences in File (Ctrl + Shift + U (Command + Shift + U on macOS)) contextual menu action. Matches are displayed in separate tabs of the Results view.
