rotation “handle” in the centre of the transform to produce an arc rotational
movement rather than rotating around the area’s centre (by default).
TIP: Holding down the Shift key whilst rotating will cause a movement in
15 degree intervals.
Making the selection larger or smaller
If the selection you've made isn't quite the right shape, or doesn't quite include all
the necessary pixels (or perhaps includes a few too many), you can continue to use
the selection tools to add to, or subtract from, the selected region.
To add to the existing selection with a selection tool:
• Select the tool and drag while holding down the Shift key. The newly selected
pixels don't have to adjoin the current selection—it's possible to select two or
more separate regions on the active layer.
To subtract from the existing selection with a selection tool:
• Select the tool and drag while holding down the Alt key.
Pressing the Ctrl key changes the tool temporarily to the Move Tool, so you can
move the selection’s content.
Modifying the selection
If you right-click (or choose the Select menu) while you have a selection on your
page, a series of selection-related commands can be used:
• The Invert command selects the portion of the active layer outside the current
selection. Unselected pixels become selected, and vice versa.
• The Modify item on the Select menu provides a submenu with several
functions that can save you the trouble of hand-drawing to change the
selection boundaries:
• Choose Contract... to shrink the borders of the selection, or Expand... to
extend its borders. Each command displays a dialog that lets you enter a
specific pixel value.
• Choose Border... to create a new selection as a "frame" of a specified pixel
width around the current selection.
