This question already has an answer here:
If I press CRTL+Down I move to the cell before the empty cell.
If I press CTRL+SHIFT+End I end up selecting everything between the active cell and the next empty cell.
Now if I want to auto fill the same range of cells, what is the keyboard shortcut for that? (Autofill; also known as clicking the handle in the lower right hand corner of the cell and dragging)
