The Lasso Tool
is a free selection tool that lets you draw your own selection outlines instead of clicking by shape or using the default dragged-square selection outline created by the Arrow Tool
. With the Lasso Tool you can click and then drag to draw any shape selection that you want; if you release the mouse, the shape will automatically close itself by connecting the open ends with a line, or you can connect the ends yourself by dragging all the way to your starting point. You can use the default tool for a rather "wiggly" selection, or you can use one of the three options at the bottom of the toolbar to help refine your selection.
