Silence text notification while ringing

[hemertwv]

Hello, I have searched the forums and didnt find an answer and i am new to android, on my bb when a notification is happening I can just hit the volume key and it silences it for that instance, on this note 4 I have I can't figure how to silence a notification while it is happening. I know how to turn them off all together, but sometimes I get into a conversation and I get a message and need to silence it right then. Help
