how do i turn on this history search in windows terminal?

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.
