Deselect Inactive
Selection > Deselect Inactive
 

Description:

      The Deselect Inactive (Selection > Deselect Inactive) command will deselect all objects which are currently selectable but have no components selected. For example, if a cube's vertices are selectable, but none of the vertices are selected, then that cube is an inactive object. This command allows you to narrow the selected (i.e. editable) objects to those you are currently working on.


Notes:

-Deselect Inactive has no effect in object selection mode.

-This command has the same effect as switching to object selection mode, deselecting the objects you want to make uneditable, and returning to the current selection mode.
