Selecting with the Marquee Tool in Photoshop

Adobe Photoshop

• Holding the Option (Mac) / Alt (Win) key while dragging with the Marquee tools creates a selection from the center.
• Holding the Shift key will constrain the Marquee to a square or circle.
• After starting to draw a selection using the Marquee tool, holding the spacebar (while still holding the mouse down) allows the repositioning of the origin of the selection. Releasing the spacebar (while still holding the mouse down) allows continuation of drawing of the selection.

    On my Mac, the Option and Shift keys have no effect on the rectangular marquee tool, (3 different versions of Photoshop.) It works as described on the elliptical marquee tool.

      Do you have MouseKeys enabled in the OS preferences?
