(ItвЂ™s a little confusing, but donвЂ™t worry-youвЂ™ll rarely use this mode.)The keyboard shortcut is Shift-Option (Shift+Alt on a PC).

If you click the Options barвЂ™s вЂњIntersect with selectionвЂќ icon after you make a selection, Photoshop lets you draw another selection that overlaps the first the marching ants then surround only the area where the two selections overlap. Mouse over to your document and draw a box (or oval) around the area you want to deselect. A tiny вЂ“ sign appears beneath your cursor to let you know youвЂ™re in this mode. Clicking the вЂњSubtract from selectionвЂќ icon (also labeled in FigureВ 4-3) or pressing and holding the Option key (Alt on a PC) has the opposite effect. Instead of starting over, simply switch to this mode and draw around that area as if you were creating a new selection. This mode is handy when you need to select areas that donвЂ™t touch each other, like the doors in FigureВ 4-3, or if youвЂ™ve selected most of what you want but notice that you missed a spot.

When you click the Options barвЂ™s вЂњAdd to selectionвЂќ icon (labeled in FigureВ 4-3) or press and hold the Shift key, Photoshop puts a tiny + sign beneath the cursor to let you know that whatever you drag across next will get added to the current selection. When youвЂ™ve got the selection where you want it, release the space bar-but not your mouse button-and continue drawing the selection.ДЄdd to the selection. In this mode, you can move a selection as youвЂ™re drawing it by moving your mouse while pressing the mouse button and the space bar. When you start drawing a selection, Photoshop activates the Options barвЂ™s вЂњNew selectionвЂќ icon (see FigureВ 4-3).
