Adding, Subtracting, or Combining Selections

Once you've made a selection, you can modify it by adding, subtracting, or combining. Here's a refresher of the options at your command.

• Choose a selection tool and add to an existing selection by holding the Shift key while you drag. You can also click the Add To Selection icon in the Option bar to temporarily make adding to the selection the default action.

• Choose a selection tool and subtract from an existing selection by holding the Alt/Option key while dragging. Or, click the Subtract from Selection icon in the Option bar.

• Click the Intersect with Selection icon in the Option bar, then create a selection that overlaps the original selection. Only the portion that overlaps the two will be selected. This useful technique can help you do things like create a particularly shaped selection. Figure 5.8 shows the results of adding, subtracting, and intersecting selections.
