This is a “I can’t believe I didn’t know that” kind of observation:
"In the history window, you can go up and down using the arrow keys. "
All these years I’ve been using the mouse which is really hard to do accurately in that window for some reason.
Thanks to greggybud for pointing this out in another post.
Also: can close the history window with a CTRL-W (Win), as long as it’s in focus. Can’t be brain-dead about that though, if it’s not in focus Cubase wants to close the whole project. But it won’t without a 2-step confirmation.
