You need the subshell enabled for this.
1. Select a harmless script or command in either pane.
2. ^O into the subshell and play a bit to make MC think you were typing

3. Press Enter to run the script or command, then again to acknowledge
4. ^O into the subshell. If your system is like mine, you'll see a copy
