Auditman - how to unblock the client index

Does anyone know the key combination to unblock a client in the auditman index. I was working on a client in auditman when the laptop power went and when i restarted the laptop auditman thinks there is another user in that client and has therefore blocked that client (has a star next to it), i know there is a key to unblock it i.e. control alt and F10 or such like but can't quite remember it. Can anyone help?
