GNOME Bugzilla – Bug 461096
Can't deselect selection

When you are playing gnome-sudoku and some box is selected, you can't deselect it, unless if you select other box. When click in a blank space, the selection should be deselected :). If you are playing with "colorize" mode, it would be useful to deselect the actual box to take a look at all other boxes.
You can deselect by shift-tabbing so that focus ends up on the toolbar. However, since there's no widget that can grab the focus in the blank area and since there's no way to move focus to the toolbar via the mouse, there's no way to move the focus off of the board using the mouse.
Colorize mode is going away in 3.14, so I don't think there's any more reason to fix this.
