To add to a selection in Photoshop using a keyboard shortcut, hold down the Shift key while making your selection.
This works regardless of the selection tool you are using (Lasso, Marquee, Magic Wand, etc.). Holding Shift will allow you to add the newly selected area to the existing selection. Let's break this down with specific examples:
- Using a Selection Tool (e.g., Lasso Tool): Select your initial area. Then, press and hold the Shift key. Use the same selection tool to draw another area. The second area will be added to the original selection.
- Clicking to Add (e.g., Magic Wand Tool): Select an area with the Magic Wand. Press and hold the Shift key, and click on another area you want to include. This adds the new area to your existing selection.
- Adding Entire Layers to a Selection (using a layer mask):
- Mac: Command + Shift -click the layer mask thumbnail.
- Windows: Control + Shift -click the layer mask thumbnail.
In summary, the primary keyboard shortcut for adding to a selection in Photoshop is the Shift key. Keep it pressed while making subsequent selections. The additional shortcut mentioned above refers to adding an entire layer to a selection based on its mask.
