l Multiple graphic objects can be selected by constructing a bounding box in the
display window. If you press a mouse button in an open area of the display
window (i.e., not on a graphic object) and drag the mouse without releasing the
mouse button, then a bounding box or “rubberband box” will be shown, where
one corner of the box is fixed at the location where the mouse button was
initially pressed, and the opposite corner tracks the current mouse position.
When the mouse button is released, all of the objects that intersect the
bounding box will be selected. Any objects that are outside the bounding box
will be deselected.
l A graphic object's selection state can be toggled between selected and
deselected, without affecting the selection state of any other objects, by
pressing the “Ctrl” key when clicking on the object. With this action, graphic
objects can be individually added or removed from the current group of
selected objects.
l A graphic object can be selected, without affecting the selection state of any
other objects, by pressing the “Shift” key when clicking on the object. When an
object is selected by this action, it becomes the “reference object” (see
Layout
Dialog
on page 194) for the group of selected objects. The primary purpose of
this action is to change the reference object in a group of selected objects prior
to invoking one of the “Layout” operations.
l All graphic objects can be deselected by clicking the mouse in an open area of
the display window, that is, not on a graphic object.
Sizing Graphic
Objects
A graphic object's size can be changed by first selecting it, and then using the
mouse to change the size of the object's selection box. As you move the mouse
over an object's selection box, the mouse pointer changes to reflect the type of
sizing operation that will be performed. If you press a mouse button while the
mouse is over an object's selection box and drags the mouse without releasing the
mouse button, then a bounding box or “rubber-band box” is shown. When the
mouse button is released, the object's size is changed to match the size of the
bounding box. There are eight possible sizing actions depending on which part of
an object's selection box is dragged. Each corner of the box will allow only its
adjacent sides to move, each side of the box will allow only that side to move.
