Moving
a selection border repositions just the border without altering
the photo.
Using any selection tool, click New Selection in
the options bar, and position the pointer inside an existing selection
border. The pointer changes to indicate that you can move the selection .
Note: The New Selection option appears in the options bar
when any selection tool is selected—except the Selection Brush tool.
Switch to another selection tool temporarily, if necessary, to select
this option.
Do one of the following:
Drag the border to enclose a different
area of the photo. You can drag a selection border beyond the canvas
boundaries; however, this makes it hard to get back. You can also
drag the selection border to another image window.
To move the selection in 1‑pixel increments, use
an arrow key.
To move the selection in 10‑pixel increments, hold
down Shift, and use an arrow key.
To constrain the direction to multiples of 45°,
begin dragging, and then hold down Shift as you continue to drag.
