I actually just figured out a way to do something like this.
- Make sure you have the file explorer pane open on the left with the “Open Editors” section open, and the chat pane open on the right.
- In the Open Editors pane, select the files you want to reference. You can click the first one and then shift-click the last one to select them all, or select them individually by Ctrl-clicking on Windows or Command-clicking on Mac.
- Drag them over to the chat pane.
Having a one-button shortcut to do this would be great, but this gets the job done for now.
