Mixer full screen and cannot be resized

I accidentally somehow made my mixer window full screen, and I can’t resize it to be smaller because all of the window “chrome” is off screen. It’s “ok” because I can still use the Windows taskbar to switch back to the application window, but there doesn’t seem to be any way to make the mixer smaller again, and it persists in all projects across relaunches and reboots.

How can I get it back to a non-maximized size?

I figured it out. In Windows, WinKey + → or WinKey + ← will snap the window to one side of the screen and resize it to show the titlebar, etc. I thought I’d tried this, but I guess not!
