solo/unsolo all channels

I can’t find a way in Cubase 9 to unsolo or unmute all tracks.
In previous versions I think I recall there use to be a universal ‘S’ and ‘M’ above the first audio channel.
Any help?
Thanks

It’s there. Make sure your mix console tool bar (the bar on top) shows it. In the mix console tool bar set up it’s called “state buttons” If you don’t see the S and the M…as well as the L, R , W, and A make sure your tool bar is set up with it shown and not hidden.

The tool tip is “deactivate all solo states”

Found it, thanks for advice!
