Default Shortcut: None
Menu Path: Display > Focus Selection
The Focus Selection command will center the current selection in the active viewport. This is useful for times when you may have rotated the camera to a position where you cannot find the object you're working on, or to quickly center a new selection in the viewport.
If you have chosen to use Framed Selection for the View Rotation Center setting in the General Settings window, then a call to Focus Selection will cause the center of the view rotation to be updated to the position of the manipulator on the current selection, where it will stay until a subsequent call to Focus Selection or Frame Selection is made.
