Smart Selection Brush Tool

Settings

The following settings can be adjusted from the context toolbar:

• Mode—sets the way in which your selection develops as you paint:
  • Add—the brush stroke adds areas to the current selection. If there is no selection in place, you will create a new selection by painting.
  • Subtract—the brush stroke removes areas from the current selection.
• Width—the brush (stroke) size in pixels. Type directly in the text box or drag the pop-up slider to set the value.
• Snap to edges—selection is expanded to the edges of content underneath the brush stroke.
• All layers—if this option is off (default), the selection is only applied to the current layer. When selected, the selection applies to all layers in your image.
• Subtract—(on-screen modifier key) when pressed, switches from Add to Subtract selection mode.
• Toggle snapping—(on-screen modifier key) when pressed, toggles selection snapping to edges.
