About This Shortcut
This shortcut extends the selection from the active cell to the cell immediately below. If multiple rows are selected, Excel will extend the entire bottom edge of the current selection by one row.
About This Shortcut
If the active cell is empty, Excel will extend the selection to the first non-empty cell to the right. If the active cell is non-empty, Excel will extend the selection on the last non-empty cell to the right. On a Mac, the command key (⌘) can be used instead of the control key.
