I have a box that appeared and I cannot get rid of it I accidently fat fingered my keyboard and a box appeared around my object...I guess it's a bounding box or something but I have no clue how to get it to disappear. When I select all objects in edit mode and move the objects the box doesn't move.  I can't edit, or resize it and if I copy my object to another scene, the stupid box goes along with it. Does anyone know how to turn this thing off?  Help would certainly be much appreciated.
Okay, I stumbled on it by accident.  I guess there is a hotkey for it somewhere.  This is a texture space.  In version 2.7x it was a yellow dotted box, but in 2.8 it looks like a bounds box.  I removed the texture space tick from Viewport Display and the box disappeared.
