Also, "=[Left-Arrow]" (or whatever) gives a neat and easy value to copy down into a lot of cells, if he actually has a whole column of values he wants to change(*). Oh well, a matter of taste, I suppose; YMMV.



(*): Get a correct value/format into the topmost one, Al, and then "paint" (i.e, multi-select) the rest of them by click-dragging with the mouse, or pressing shift-[Down-Arrow]; then finally press Ctrl-D.
