Analagous to CTRL-Z and SHIFT-CTRL-Z for the “old” history that works for everything but the mixer.
if the left zone is focused on any of the 3 mix consoles, and the history tab is open, you can use the up/down arrows just like the history window.
when the left zone is focused, pressing tab should rotate through the 3 tabs in the left zone.
remember whatever tab you left open in the left zone, for example mix history, then when you re-open the left zone, mix history should open.
I hope this is all correct…Alexis correct me if I’m wrong.
