Chapter 8 Working with Shapes, Graphics, and Other Objects 159
For shapes, you can set opacity for fill and stroke colors separately from object opacity. If
you move the Opacity slider in the Colors window to modify a fill or stroke color, that
opacity value becomes maximum object opacity. Then, when you change the object
opacity in the Graphic Inspector, you are changing it relative to the opacity you set in
the Colors window.
If you change an object's opacity and then can't restore the object's fill color to 100%, it
may be because the opacity was set to less than 100% in the Colors window. To fix it,
select the object, choose View > Show Colors, and then set the opacity in the Colors
window to 100%.
Grouping and Locking Objects
Group objects you want to keep together, and lock objects you don’t want to
inadvertently move.
Grouping and Ungrouping Objects
You can group objects (except tables) together so that they can be moved, copied,
resized, and oriented as a single object. You can edit text associated with a shape or
text object in a group, but you can’t modify other attributes of individual objects in the
group.
To group objects:
1 Hold down the Command (or Shift) key as you select the objects you want to group.
The objects can’t be locked.
2 Choose Arrange > Group.
To ungroup a grouped object, select the group, and then choose Arrange > Ungroup. If
the group is locked, unlock it first.
