MC Mix channel mode

Hi All,
I'm still just trying to learn how to navigate around the MC Mix. I can't seem to get the MC Mix out of channel mode to go back to mix mode. It was working fine but then I pushed some mysterious button combination that has now put me into a stubborn channel mode.

In the Euphonix tutorial videos the left hand buttons appear red when lit. Mine remain yellow and I only see the track that I have selected in Logic as the first channel with it's related buses going to the right. I know that this is an option but I can't seem to return to the channel mix mode.

And it's odd that my buttons remain yellow. The record button turns red. Is there anyway to return to the default settings? I'm in a jumble:)
