The Zoom Tool is used to change the zoom level of your working image.
If you only click on the image, the zoom is applied to the whole image.
But you can also click-and-drag the mouse pointer to create a zoom
rectangle. Then, the action of this rectangle is better understood if the
“Allow window resizing”
option is unchecked: you can see that the content of this rectangle will
be enlarged or reduced so that its biggest dimension fit the corresponding
dimension of the image window (if the biggest dimension of the rectangle
is width, then it will fit the width of the image window).

level. For example, you can easily choose an exact magnification
level from this menu.
