Displaying Pre-Shared Key on a Cisco ASA 55X0 Device

I recently had the task of moving four Cisco ASA 5540 devices from one location to another.  The big headache I found was that no one remembered the Pre-Shared Keys for the tunnel groups.  A simply show running-config shows only **** for the PSKs.  A bit of digging on the Cisco site resulted in the following command:

more system:running-config

This will show all hidden entries in the running config as clear text.
