 ## Opening Documents
 
-When you click **Go to** or double-click a document entry in Level 1, the document opens as it currently exists in your app. If the document no longer exists in your current state, Level 2 and 3 is shown but nothing opens in the editor.
+When you click **Go to** or double-click a document in Level 1 or an element in Level 2, the document opens in the editor. The version that opens depends on the document type, the status of the document, and the type of comparison.
 
-For text-based properties, you can double-click a property row or use the context menu to open a detailed side-by-side comparison in the [File Differences Viewer](/refguide/file-diff-viewer/). For file-type documents in Level 1, double-click or click **Go to** to open the File Differences Viewer instead of a document editor.
+### Document Types with Read-Only Versions {#read-only-versions}
+
+For the following document types, you can open the version of the document from a specific revision:
+
+* Microflows
+* Workflows
+* Nanoflows
+* Domain model
+
+These versions open in a separate tab in read-only mode. You cannot edit the document or its properties. The tab indicates whether it shows the **Older** or **Newer** version. Read-only tabs close when you stop the comparison.
+
+The table below shows which version opens when you click **Go to** or double-click a document:
+
+| Status | Compare to Current State | Compare Revisions |
+|--------|--------------------------|-------------------|
+| **Added** | The current version opens in edit mode | The version from the newer revision opens in read-only mode |
+| **Modified** | The current version opens in edit mode | The version from the newer revision opens in read-only mode |
+| **Deleted** | The version from the selected revision opens in read-only mode | The version from the older revision opens in read-only mode |
+
+To open a specific version, right-click a document in Level 1, select **View**, and then select one of the following options:
+
+| Option | What Opens | Available For |
+|--------|------------|---------------|
+| **Older** | The version from the older revision, in read-only mode | Modified and deleted documents |
+| **Newer** | The version from the newer revision, in read-only mode | Added and modified documents, when comparing two revisions |
+| **Current** | The document as it is in your app now, in edit mode | Added and modified documents |
+
+### Other Document Types
+
+For all other document types, the document opens as it currently exists in your app, regardless of the type of comparison. If the document no longer exists in your app (for example, because it was deleted), a message says so and nothing opens.
+
+### Files and Text-Based Properties
+
+For text-based properties, double-click a property row or use the context menu to open a detailed side-by-side comparison in the [File Differences Viewer](/refguide/file-diff-viewer/). For modified file-type documents in Level 1, double-click the document or click **Go to** to open the File Differences Viewer instead of a document editor. You cannot open added or deleted files.
