Creates a select area in a raster image by drawing a rectangle around pixels that you define.
A select area is a user-defined area of individual pixels or groups of pixels within an image. You can create a select area for editing purposes.
When you drag the crosshair to define a rectangular select area, a solid rectangular outline dynamically appears as you drag. When you reach the desired size, release the mouse button to create the select area. The solid select area outline then becomes a dotted outline.
As you create a select area with the Rectangular Select Area command, you can use the following modifier keys to change the default behavior of your selection:
