Choose Window > Layers.
From the Layers palette menu, choose Locate Object. The name of a clipping path 
appears in the palette with a solid underline. Clipping groups appear with dotted-line 
separators.
Note: You can also select all masks in your artwork by using the Clipping Masks command 
in the Select menu. (See 
.)
Creating masks
A masking object can consist of a single path or a compound path. 
To mask objects: 
Draw or use the selection tool to select the object to use as a mask. 
Make sure that the object is on top of the objects you want to mask. 
When you mask objects on different layers, keep in mind that objects on intermediate 
layers become part of the masked artwork. 
Select the mask and the objects you want masked. 
Choose Object > Clipping Mask > Make. The mask loses its paint attributes and is 
assigned a fill and stroke value of None. 
To undo the effects of a mask:
Use the selection tool or drag a marquee to select the objects you no longer want to 
use as a mask. 
Choose Object > Clipping Mask > Release. 
Because the mask was assigned a fill and stroke value of None, it is not visible unless you 
select it or assign it new paint attributes.
Modifying and selecting masks
Once you create a mask, the mask and the masked objects can be selected and modified 
as any other object. Masked objects are unlocked by default. You can lock the mask so that 
mask objects are secured together. By locking the mask, individual objects cannot be 
unintentionally moved with the direct-selection tool.
The Clipping Masks command in the Select menu finds and selects all masks in the 
document. If objects are selected, the command deselects any objects that are not masks.
When you rasterize a mask, the full stroke value of the mask is displayed. 
To select all masks in a file:
Choose Select > Object > Clipping Masks.
To find out which objects are affected by a mask:
Select the group-selection tool.
Click the mask once to select it, and then click once more to select the objects in the 
corresponding clipping group.
To add an object to masked artwork:
Use the selection tool to select the object to add to the masked artwork, and drag it in 
front of the mask.
