Help to disable black console

[Ganspe]

Please help to disable thr black console in Mac loin mountain. I dont know what is this. It has appeared since kinds played with the keyboard😀
It is always on top. Can be resized. It is commenting my actions e.g "you are currently on a Folder". It is annoying when you dont know how to use it. Thanks

Sounds like some sort of accessibility type of feature that you should check in settings under universal access or something of that sort.
