Choose a target layer from the Choose Destination Layer drop-down menu. 3
Click OK. The visual indicators for the merged items display the color of the 4
layer to which you merged, and the layers that you selected for merging are
deleted.
Layers cannot be merged when one of the selected layers is locked. 
Items may be merged from the Default layer, but the Default layer is never 
deleted by a merge operation.
Locking items on layers
To avoid inadvertently making changes to items on a layer, you can use the
Layers palette to lock the entire layer.
Layer locking is independent from item locking. Items locked using Item > Lock
can still be selected and edited; items on a locked layer cannot be selected at
all. If you lock an item on a layer using Item > Lock, and then lock and unlock the
layer, the item retains the item lock even after the layer is unlocked.
The Lock column in the Layers palette controls the locking of layers. To lock
layers, use one of the following methods:
To lock or unlock a layer, click in the Lock column to the left of the layer’s ●
name. You can also double-click the layer to display its Attributes dialog box,
check or uncheck Locked, and then click OK.
To lock all but one layer, press Command/Ctrl and click in the Lock column ●
next to the layer you want to edit.
To lock all layers, choose Lock All Layers from the palette menu. ●
Using master pages with layers
You can also use layers on master pages. Remember that items that come from
a master page that reside on the same layer will always be positioned behind
items on the document page.
If you downsave to QuarkXPress 9 (which did not support layers on master 
pages), all items on the master page will be put on the default layer and this
might create a different stacking order than existed in QuarkXPress 10.
Suppressing printout of layers
Just as you can suppress the printout of items such as picture boxes, you can
suppress the printout of layers. To suppress the printout of a layer, double-click
that layer in the Layers palette. In the Attributes dialog box, check Suppress
Output, and then click OK.
