How to work with the Selection Tool
To work with the Selection Tool
Click the Selection button on the Tool palette.
Place the mouse on the image at one of two places:
To create a rectangular, square, or rounded rectangular or square selection, place the cursor at a corner of the area you want to select.
To create a circular or elliptical selection, place the cursor at the center of the area you want to select.
To create a selection using the other shapes, place the cursor at a point that would form the corner of an imaginary rectangle enclosing the shape.
Click and drag the mouse until the selection is the size you want. As the mouse moves, a line appears to indicate the border of the selection.
Release the mouse button. The selection border will become a marquee.
