PRO-91 Help put in trunking mode

[huricane]

I got my 5 freqs. programmed into bank 2 and im just scanning that bank to listen. Iv been away from the scanner for awhile and forgot how to set bank 2 into trunking mode. It would just display the Talkgroup# when someone keyed up. Now i just see freqs flying by conventional style. Thankful for any help, Dave.
