Shortcut Shift+T move texture space pressed in error

I pressed Shift +T instead of Ctrl+T and now have a rectangular selection box on the screen -how do I remove it. After googling nothing comes up.

thanks

Ken

In the Object Properties (cube icon) / Dsiplay, turn off the ‘Texture Space’ display

Thanks Richard
