## Bridge context between Hub panes

When [Split Panel](/getting-started/split-panel) is open in the Hub, you can copy context from one pane to the other:

* Drag context cards from the conversation—or items from the prompt **context strip**—to the other pane
* Right-click a conversation tab → **Add as Context to Other Pane**
* Type **`@`** and choose the conversation listed under **Other Pane**
* Right-click context cards, images, or documents in a message → **Add to Other Pane**
