Every so often, I accidentally activate .... what ever this is... I can't seem to find any info on what it's called, or exactly what hotkey makes it happen. It kinda bugs me because tonight I wanted to turn it on, because I wanted to access something from my history that it would have been tedious to up arrow to. I thought windowsKey + , did it, but when I tried it in a new tab, it didn't work. Someone must know what this is and how to toggle it.
Pretty sure powershell had a F7 key to show a history window. Looks like that might have carried over to Windows Terminal.
