+### Duplicating / Copying Comments
+
+Kanvas supports two ways to reuse comments: **Duplicate** and **Copy**. Both create a new comment based on the original, but they serve different use cases.
+
+#### Why Use Duplicate?
+
+Design reviews often involve evolving threads or multiple subtopics. Duplicate is ideal when:
+
+- **Preserving Valuable Context**  
+  Long threads may include resolved and unresolved content. Duplicating preserves ongoing relevance while letting you resolve the original.
+
+- **Managing Multiple Action Items**  
+  Break down one thread into focused, actionable items. This improves clarity and prevents blockers from holding up the discussion.
+
+#### Why Use Copy?
+
+**Copy** is helpful when you need flexibility to place the comment somewhere else—either within the same design or across different ones.  
+This method supports:
+
+- **Manual Placement**: Paste the copied comment exactly where you need it.
+- **Bulk Operations**: Copy multiple selected comments at once using mouse drag.
+
+{{< alert title="Tip: Comment participants' access to designs" type="info">}}
+
+Copying a comment into another design does **not** change the target design’s sharing settings:
+
+- Participants from the original thread may not have access
+- Notifications may still be sent, but users might not be able to view or respond
+
+Learn more about [sharing settings](/kanvas/designer/sharing).

+
+#### How to Copy or Duplicate
+
+- **Right-click and Copy**: Choose **Copy** to manually paste it later.
+
+  <figure style="width:400px;">
+    <img src="./comment-copy.gif" alt="Copy a comment" />
+    <figcaption>Copy a comment</figcaption>
+  </figure>
+
+- **Right-click and Duplicate**: Use **Duplicate** to instantly create a copy in the same design.
+
+- **Keyboard Shortcuts**:
+  - <button class="kbc-button kbc-button-xs">Ctrl + C</button> / <button class="kbc-button kbc-button-xs">Ctrl + V</button>: Copy and paste
+  - <button class="kbc-button kbc-button-xs">Ctrl + Z</button>: Undo the action

+
+#### Naming Matters
+
+Kanvas auto-generates comment names, useful for quick feedback. When duplicating or copying for tracking or history, **rename the copy** to reduce confusion and aid navigation.
+
+#### What Happens When You Duplicate or Copy a Comment?
+
+- **Timestamp**: The original creation time is preserved.
+- **Threads**: All replies in the original thread are included.
+- **Name**: If the comment has a name, the clone keeps the same name.
+- **Placement**:  
+  - **Duplicate**: Instantly places the comment in the same design.  
+  - **Copy**: Allows you to paste the comment manually into the same or a different design.
+- **Notifications**: Neither duplicating nor copying sends a creation notification to the design owner or participants. However, replies to the cloned comment will notify participants unless they’ve muted the thread.
+- **Independence**: The clone is separate—editing or deleting the original does not affect the copy.

 ## Best Practices for Effective Design Reviews
 
+### Resolving vs deleting comments
+
+Resolving a comment hides it from the canvas but keeps its history, so you can always revisit or reopen it later. Deleting a comment removes it entirely — including all threads and history — and cannot be undone.
+
 ### Be specific and actionable
 
 Provide specific feedback that the designer can act on. Vague comments can lead to misunderstandings and delays in the design process. Support your feedback with examples or references. This can help clarify your point and provide the designer with tangible suggestions for improvement.
