The Auto Shrink Selection checkbox will make your next selection automatically shrink to the nearest elliptical shape available on the image layer. The algorithm for finding the best ellipse to shrink to is "intelligent", which in this case means that it sometimes does surprisingly sophisticated things, and sometimes does surprisingly strange things.
In any case, if the region that you want to select has a solid-colored surround, auto-shrinking will always pick it out correctly. Note that the resulting elliptical selection does not need to have the same shape as the one you sweep out.
If Sample Merged is also enabled, then the Auto Shrink will use the pixel information from all the layers of the image. For further information regarding Sample Merge, see the glossary entry Sample Merged. This menu allows you the option of constraining the shape of the ellipse in three different ways. Fixed Size. This will allow you to manually specify a size for the selection using the Width, Height, and Unit controls.
Antialiasing: helps to prevent jagged edges. Feather edges: softens the edge of the selection. Expand from center: expands outwards from start point.

This tool is also used for rendering a circle or ellipse on an image. To render a filled ellipse, create an elliptical selection, and then fill it using the Bucket Fill tool. To create an elliptical outline, the simplest and most flexible approach is to create an elliptical selection and then stroke it. However, the quality of anti-aliasing with this approach is rather crude. A higher quality outline can be obtained by creating two elliptical selections with different sizes, subtracting the inner one from the outer one; however this is not always easy to get right.
By clicking on the tool icon in the ToolBox,. See Selection Tools for help with modifier keys that affect all these tools in the same way. Only effects options that are specific to this tool are explained here. Pressing the key after starting your selection, and holding it down until you are finished, causes your starting point to be used as the center of the selected ellipse, instead of a corner of the rectangle that may contain it.
Note that if you press the Ctrl key before starting to make the selection, the resulting selection will be subtracted from the existing selection. Pressing the Shift key after starting your selection, and holding it down until you are finished, constrains the selection to be a circle.
Note that if you press the Shift key before starting to make the selection, the resulting selection will be added to the existing selection. Pressing both keys combines the two effects, giving you a circular selection centered on your starting point. When this tool is selected the mouse pointer comes with a circle icon as soon as it is over the image.
