Use the color worksheet in the Design Panel, and the Hide Object Types filter buttons in the Edit tab to show and hide the desired blocks of colors and object types in the design. You can also use the Draw Range slider bars on the Edit tab and the FilmStrip to change the view of the design.
Use any combination of color block display, object filters, draw range and FilmStrip options to hide objects. Hiding objects leaves the visible objects available for other functions without affecting the hidden objects. Use this to help when you need to select a particular set of objects that might be difficult to isolate directly with the Select functions. For example, you may wish to change the pattern in all fill areas of one type using Global Properties, or select a number of objects to copy them.
