Part of the Interface disappeared while I was sculpting today a part of my interface disappeared while accidentally hitting a key combination I don't remember. The interface only changed in Sculpting mode and it only changed in this project, it's back to normal when I open a new project. Is there a way to fix this?
I think you pressed CTRL + SPACE. The shortcut maximizes the view of the window you are hovering over.

Note : If you emulate a 3-button mouse, the shortcut is ALT +  CTRL + SPACE.

Press this combination again to go back to normal.
