Chapter 2 Creating and Managing Projects 241
When you have more than one group, you can move layers back and forth between
them, changing their nested relationship in your project.
To move a layer from one group to another:
1 Select one or more layers.
2 Do one of the following:
 Drag the selected layers to a new position underneath another group.
A position indicator appears to show the new position the selection occupies when
you release the mouse button. If you drag the selected layers within a nested group,
the length of the position indicator shows which position the selection occupies
within the group hierarchy.
 Select one or more layers, choose Edit > Cut (or press Command-X), then select the
group you want to paste into, and choose Edit > Paste (or press Command-V).
You can also copy a layer from one group to another.
To copy a layer from one group to another, do one of the following:
m Option-drag one or more selected layers from one group to another.
m Select one or more layers, choose Edit > Copy (or press Command-C), then select the
group you want to paste into, and choose Edit > Paste (or press Command-V).
Nesting Groups Inside Other Groups
In addition to nesting layers inside groups, you can also nest groups inside other
groups. You might do this if you’re creating a layer hierarchy to control the relationship
of one group of layers to another, or if you’re grouping layers to which you want to
apply a single set of behaviors and filters.
Nesting a group works the same way as nesting a layer.
To move a group inside another group:
1 Select one or more groups.
2 Do one of the following:
 Drag the selected group onto another group.
 Drag the selected group to a new position underneath another group.
 Select one or more groups, choose Edit > Cut (or press Command-X), then select the
group into which you want to paste, and choose Edit > Paste (or press Command-V).
Grouping and Ungrouping Layers
You can also nest layers together within a new group using the Group command. You
can group layers that appear within the same group, or you can group groups that are
all nested at the same level relative to the hierarchy of your project. You cannot group
groups that appear at different levels.
