BCD996XT Quick Keys

Hello all.....I have a quick question about accessing the syste quick keys and quick keys within a group....First off, the system quick keys after 0-9......How do you access them after 0? Obviously I know how to do 0-9....You just hit the approprate number for that system you program for that key(i.e. Omaha is set for 0, so when I am ready to listen to Omaha, I just hit 0 to add it to my active scan list, and vice versa when I am ready to turn it off....But I do not know how to access any systems after 9. If someone with the knowledge can help me out, that would be greatly appreciated.
Secondly, how to access a quick key for a certain group within a system.
