Center pivot points and hypershade

One thing that i found useful is the center pivot point feature. i notice everytime you combine and seperate an object the pivot point will always change and so i found out how to center pivotpoint by clickin on a key. this is accessable through:

Toolbar# Modify > Center Pivot

another thing i found useful is that when assigning a object to an existing material. it is easier to select all your multiple objects and then go to hypershade right click select the material then "assign to selection". i do this because i found out you can't do it in perspective view. when you muti select and assign to existing lambert. only one objects gets assigned. not all that is selected.
