Extend the selection to the last cell down

Windows shortcut 
CtrlShift
Mac shortcut 

If the active cell is empty, Excel will extend the selection to the first non-empty cell below the active cell. If the active cell is non-empty, Excel will extend the selection on the last non-empty cell below the active cell. On a Mac, the command key (⌘) can be used instead of the control key.
