I wonder if this may help.
1. Open a greyscale image
2. bring up the Adjust Threshold dialog and move the boundary thresholds.
This will show in red the threshoded areas.
3. select the Wand tool and click on the image where you want to select
the area.
The wand selects the thresholded area (it appears with a yellow perimeter.
Now you have 2 options
4a. Fill the area (the connected area will be in the foreground colour)
4b. Go to Edit Selection Make Inverse and fill (this will leave the
connected area as original and fill the rest with the foreground colour.
