3.14. Fill with BG Color

This command can be accessed from an image menubar as Edit->Fill with BG Color, or by using the keyboard shortcut Ctrl-..

"Fill with BG Color" causes the image's selection to be filled with the solid color shown in the Background part of the Color Area of the Toolbox. (The color is also shown to the left of the menu entry.) If some areas of the image are only partially selected, they are filled in proportion to their degree of selectedness.
