You can hide any objects in your scene and you have the option to hide any selection of objects or to hide anything except your current selection of objects. Hidden objects differ from frozen objects in that they disappear from the viewport instead of turning dark gray. If you are working on a scene that includes many objects or you have many objects in a very tight area, hiding some of them gives you more access to the unhidden objects and speeds up redraws.

You can hide an object that includes a target (such as target cameras, tape helpers, or suns) by choosing either the head or the target object and then selecting hide.

Hide and Unhide are accessible from the Display panel or from the Display quadrant of the Quad Menus.
