This means: go one step back. Repeatedly tapping the F3 key leads to the exit: the end of a session. I noticed that the PF3 command is also labeled as &#8220;End&#8221;. This means that if you read : &#8220;enter end command to return to the primary option menu&#8221; should be interpreted as press F3 to return.
