Good instructions...one thing to note is when you are wanting to a cell by including "$", for another shortcut you can use the F4 key to lock the referenced cell in. Try it...1st time keying F4 locks the whole cell reference (e.g. $C$4), 2nd time locks only the row reference (e.g. C$4), 3rd time locks only the column reference (e.g. $C4) and 4th time unlocks the cell reference (e.g. C4).
