What are these buttons for?

On the Vista EX console there are three buttons that seemingly don’t have any function…

I’ve tried figuring out what they do, and I’ve also searched this forum, and whatever documentation there is about the console, but I can’t figure out what they do… Does anyone have any idea?

Hovering over that button on the left in the software tells me that the button is for direct mode. But what is that?

P.S. I’ve figured out that the expand button makes the list of the cues larger, but does it have any other functions besides that?

They are for future use, they currently do not do anything.

The expand button does only what you have already found at this time.
