This command is only available from within the interactive report and its behavior is dependent on the type of display from which it is invoked:
Event Details
Use this command to select the next event. For example, if you are currently displaying event number 2, entering this command displays event number 3, if available.
Dump Storage
The storage address displayed prior to entering a PREV command is shown again.

This command is usually assigned to the PF11 function key.
