Expands the current selection to include all directly connected geometry. Geometry is considered connected if the graph of faces can be traversed from one point to another.

Note that you can also perform a [link]Flood Fill Selection by mousing over a face and pressing Ctrl+F, which will select all contiguous unselected faces that can be reached from the face currently highlighted by the mouse. In contrast to Select Connected, Flood Fill Select will not continue its search beyond faces that are already selected, so a region to be newly selected can be contained by first selecting an unbroken boundary around it.
