It is a common exercise in Photoshop to make a selection and then need to add to or delete from that selection instead of starting from scratch. While you can always use the Add and Delete buttons in the Options bar for selection tools, it's must quicker and easier to use the keyboard commands to do so.
TRY IT To use a keyboard command to add to or delete from a selection, first click any of the bitmap selection tools—Marquee, Lasso, or Magic Wand—and make a selection in an open file in Photoshop. Then, follow these instructions:
1. To add to the existing selection, hold down the SHIFT key and use the selection tool again on your image. You'll notice that when holding down the SHIFT key in this instance, the cursor has a plus sign next to it.
2. To delete from the existing selection, hold down the ALT key (Windows) or OPTION key (Mac) and use the selection tool again on your image, somewhere inside the existing selection. You'll notice that when holding down the ALT key in this instance, the cursor has a minus sign next to it.
