This article explains how to view a document in Opus 2 using the document preview and document viewer, and outlines the key panels and tools available when reviewing a document.


The Opus 2 document viewer allows users to open, read, and interact with documents directly from the Documents page. From the viewer, users can navigate between pages, search within the document, apply annotations and actions, and review notes associated with the document.

Documents are initially previewed in the right‑hand panel, and selected pages can be opened in the full document viewer, which defaults to opening in a new browser tab for focused review.

How to View a Document

  1. Navigate to the Documents page.
  2. Highlight the document you wish to view.
    • If needed, use the Find feature to locate the document.
  3. The document preview is displayed in the right‑hand panel.
  4. Use the page numbers at the top of the preview to navigate to the desired page.
  5. Click on the page preview to open the document in the Document viewer.

By default, the Document viewer opens in a new tab, allowing uninterrupted document review. Example:
Select a witness statement from the Documents table, navigate to page 3 in the preview, and click the preview to open the document at that page in the viewer.

Understanding the Document Viewer

The Document viewer is split into three panels, each providing different functionality.

    Displays all pages of the document as scrollable thumbnails. Clicking a thumbnail opens the corresponding page.

    Provides an alphabetical list of words contained in the document.

    • Selecting a word shows all instances where it appears
    • Selecting an instance opens the document at the relevant page and highlights the word

Main (Center) Panel

The center panel displays the full document. 

  • Users can read, review, and interact with the document content
  • The toolbar at the top provides key controls:

  • Page navigation controls
  • Zoom in and zoom out tools

Right side of the toolbar

  • Tools to interact with the document
  • Quick links and selection tools
  • Options to apply preset actions and annotations to selected text or regions 

Right‑Hand Panel

The right‑hand panel displays all saved notes associated with the document. 

  • Users can filter or reduce the number of visible notes
  • Clicking on a note:
    • Opens the document on the relevant page

Example:
Clicking a note in the Notes panel opens the document directly at the referenced paragraph.


Use the document viewer panels and tools to efficiently navigate, search, and annotate documents, ensuring quick access to critical information during review and case preparation.
